[Galaxy S III General] TotallydubbedHD:
Hey guys,

I'm on LF2 - rooted

I do my listening with the PFE232's

After reading here, I did some testing.

I can hear a random crackling sound for less than a second.

Goes out to both channels (left and right).

I've tried testing it with screen on and screen off, and it seems when the screen is off, is when I can notice it.

I've tested it with poweramp, and the stock music player, it happens on both players.

It is very faint....but this is actually shocking, how I never paid attention to it.

Now I'm looking out for it.

I'll report back with any more details.

Let me know if I can test by any means.
[Galaxy S III General] gavinfabl:
Can confirm I have heard the noise via my Bose AE2i.
[Galaxy S III General] crimper:
Hey, if you're rooted why don't you try changing your governor to "performance". This trick has worked on early X10 Gingerbread and early Galaxy Nexus firmwares with the same problem.
[Galaxy S III General] goody_23:
good its seems a lot more ppl are experiencing this crackling sound its a shame really because the audio quality is very good ..i will keep my phone but i need this problem sorted pronto....can more ppl test and confirm on here i want to send this link to samsung to get their finger out and sort it...
[Galaxy S III General] Haunther:
Unfortunately I didn't come across this thread until today. I bought my phone roughly about 2 weeks ago and was experiencing the crackle sound once every 30 seconds or so. At first I was thinking "maybe it was the headphones?" so I tried a few other pairs and had the same problem still. Then today, I finally decided to get a brand new replacement however my new phone has the exactly the same issue. I tested it in store and it was fine, however I had the display on whilst I was tested it, so I definitely think it's a power issue. I've let Samsung know via Facebook and they usually pass on the message...
[Galaxy S III General] omersak:
random crackling confirmed on my hifiman RE0's and the now dead RE252's. it isn't very frequent though, maybe once every 4-5 minutes. Still, unbearable when it does happen.

Thank god for the E7.
[Galaxy S III General] TotallydubbedHD:
I don't know where I could set that...without having a custom rom on it, or kernel.
[Galaxy S III General] ama3654:
all my music are in 24/96 flac and they sound awesome and pure clean using poweramp sennheiser
[Galaxy S III General] studiominal:
Lets hope we will hear the answer to this problem next week from Samsung, and keep your eyes on samsung-updates.com for hotfix :D
[Galaxy S III General] knights.JayTana:
i wonder when can we have Supercurio's Magic?
[Galaxy S III General] crimper:
No need for custom rom, any CPU control tool, SetCPU or its free alternatives. OSMonotor can do it too.

Custom roms provide additional governors, but interactive (the default) and performance are part of stock android kernel.
[Galaxy S III General] Haunther:
It doesn't matter about the quality of the song, it's most likely a power/resource issue whenever the screen is turned off. Although, the power-amp thing is interesting though; If power-amp demands more resources and the stock kernel is happy to give it then maybe that's worth a shot.

I do however think that most/all Galaxy S3's are affected by this as I exchanged mine yesterday thinking mine was faulty, only to realise the new one has got the exact same bug.

@ama3654 Turn your screen off and listen to some softer/classical music and let us know if yours is still fine. I find it's more noticeable when I listen to the Jeremy Soules Oblivion & Skyrim soundtracks; it crackles/pops every 45 seconds or so.
[Galaxy S III General] TotallydubbedHD:
good shout, didn't think of the apps.
[Galaxy S III General] knights.JayTana:
So the crackling issue is just noticeable when screen is turned off? just to make it clear.
[Galaxy S III General] TotallydubbedHD:
yes, and you have to really listen carefully to hear the crackling.
[Galaxy S III General] knights.JayTana:
ill test and make feedback shortly... are you guys rooted or completely stock? i mean those who who have the said issue?
[Galaxy S III General] plosch:
It seems that Samsung went busy reading some forums on the Internet.

Yamaha is wonderful to manufacture motorcycles. I love their motorcycles.

Knowing that the SGSIII may sound even better than the SGSI is priceless.

supercurio, super thank you!
[Galaxy S III General] Kendoji:
Hearing this (and even just a glimmer of hope for USB audio) is enough to start swaying me back to the SGSIII. :)
[Galaxy S III General] ph00ny:
Yamaha actually makes solid audio products but the SGS2 was a disappointment in that department

As for Samsung reading up on forums and comments, it's nothing new

There was an article about how the design team for samsung series 9 laptop read up on the comment sections of these tech blogs and used it for the second version

Here is a quote from engadget
[Galaxy S III General] plosch:
This attitude seems to me obvious. Let's hope other manufacturers do the same.

Thanks for the info.

Cheers,

Peter
[Galaxy S III General] varunkumars:
I am very glad. This is the only point why i would get this phone. Hopefully it supports USB DAC too.
[Galaxy S III General] lgkahn:
very glad will definately get one now
[Galaxy S III General] Caladbolg:
Pretty much every smartphone coming out now supports MHL, if I'm not mistaken, especially these halo phones. So I'd say 95% chance.
[Galaxy S III General] supercurio:
MHL is HDMI (meaning: SPDIF) not USB Audio.
[Galaxy S III General] varunkumars:
Like WM8994 in Galaxy S / Nexus S, except:

1x stereo DAC instead of 2x.

WM1811(Galaxy S3):

ReTune™ Mobile 5-band, 4-channel parametric EQ

WM8994(Galaxy S):

ReTune™ Mobile 5-band, 6-channel parametric EQ

So, does it (WM1811(Galaxy S3)) not result in lesser Sound quality as compared to WM8994 in Galaxy S ??

I see the dimensions of WM1811 are compact as compared to WM8994 though.

WM1811 : 80-ball W-CSP package (4.148 x 3.866 x 0.596mm) vs WM8994: 72-ball W-CSP package (4.511mm x 4.023mm x 0.7mm)

Specs:

http://www.wolfsonmicro.com/products/audio_hubs/WM8994/

http://www.wolfsonmicro.com/products/audio_hubs/WM1811/

I don't see how Galaxy s3 can sound better than Galaxy s. At most it can be on par.
[Galaxy S III General] habylab:
Hmm, that's true.

Sent from my Galaxy S running Slim ICS 3.5 and Midnight kernel from my XDA Premium app.
[Galaxy S III General] supercurio:
You know, on mobile its even more flagrant than on other platform hardware implementation and external parameters have a huge impact on the resulting sound quality.

Take Optimus 2x for instance. Same WM8994 as others but because of several shortcomings it doesn't sound as Samsung devices.

Not to mention stability of SoC PLL clock generators, power headroom for headphone and speaker amp etc.

Which means nobody (including me of course) can pretend to know anything certain about sound quality of a device before listening and measuring its output,
[Galaxy S III General] ph00ny:
Any word on APT-X support?
[Galaxy S III General] NZtechfreak:
Yes, official confirmation came from CSR yesterday in their Twitter feed :)
[Galaxy S III General] ph00ny:
Awesome because 7.7 sounds awesome with apt-x headsets. I'm still waiting for the right one but the demo unit i tried at the local J&R sounded amazing
[Galaxy S III General] nikzDHD:
Nice, using aptX with my HOX and it sounds fine however the SGS Voodoo'd still outshines it. Very tempted now to get the SGS3 as it's gone back to roots on the dac which means less devices for me to carry.
[Galaxy S III General] brent8577:
What is wrong with the thread I made? Sometimes I wonder how you people manage to operate computers. My thread started before this. I guess anyone can be a mod.
[Galaxy S III General] NZtechfreak:
Are you the same guy who was crying about his spurned thread in the One X forum too?
[Galaxy S III General] ph00ny:
Which APT-X headset did you use?
[Galaxy S III General] NZtechfreak:
I have the HS3000 from Samsung, Apt-X works well with that and my One X. Sounds as good as wired for up to ~370kbps is CSRs claim, I tried some 320kbps mp3s and it seemed the same as wired (just shame that the One X output isn't that good to begin with). I like the HS3000 since I can use whichever headset I like with it, or even connect it via 3.5mm-3.5mm to any speaker/stereo with a 3.5mm input (also the HS3000 is pretty cheap).
[Galaxy S III General] nikzDHD:
Samsung HS3000, as mentioned above it allows any 3.5mm headphones to be attached.
[Galaxy S III General] krypton_the_slayer:
Hello again you lucky S3 users.

I have a Galaxy note, with a kernel that supports USB audio devices. It's working but its not quite recognised in the same way that the S3 is.

Trying to implement sound output using ALSA, I wonder if any you could post a copy of your /system /etc/asound.conf file?

Thanks:)
[Galaxy S III General] goody_23:
well i am using stock firmware ,i heard the crackling sound immediately i started using the s3, and its good that a lot of ppl are picking it up ..i suspected it was an issue with all the phones that's why i never tried to get a replacement.. somebody just confirmed that a few posts ago... Samsung we are waiting for your hotfix!!!
[Galaxy S III General] chouck:
I just got 4.0.4 on my Xperia Ray, How to see if USB Audio is supported by it?

Is there any option in settings to enable ?
[Galaxy S III General] Aimara:
those having cracking issues can try good old winamp player , i didnt notice any cracking sound from winamp

those who have tried winamp, do update
[Galaxy S III General] knights.JayTana:
you're in the wrong board.
[Galaxy S III General] chong81:
Anyone using CM9 already? Is the crackling issue still present?
[Galaxy S III General] chouck:
my question is general how to see in Android OS that is supports USB Audio?

is there any extra option in Sound settings etc?
[Galaxy S III General] Haunther:
Just tried the Poweramp trial myself and it's not fixed the problem. :(
[Galaxy S III General] goody_23:
Looks like only samsung can fix this and i bet you all the handsets have the crackling sound but ppl dont just notice it enough ..
[Galaxy S III General] kurama.k:
I don't know if this is a good idea but I think we should notify techsites like gsmarena and others about this problem so more and more people will try and notice this issue, and hopefully Samsung will fix this for us and future handset's :D
[Galaxy S III General] NZtechfreak:
Samsung added their own USB audio drivers, apart from the Archos G9 no other Android devices I'm aware of have USB audio on stock fimrwares/kernels. It isn't inherent to Android 4.0 and I very much doubt your Sony has it.
[Galaxy S III General] omersak:
Listening with CM9 for around 10 minutes (screen off etc.) and no crackling yet.. the output EQ seems a bit different though - the highs are harsher
[Galaxy S III General] TotallydubbedHD:
I'm rooted on stock.

---------- Post added at 10:31 PM ---------- Previous post was at 10:30 PM ----------

Interesting - highs might be due to DSP - check EQ settings.
[Galaxy S III General] omersak:
No DSP and EQ disabled in in CM9 music player. I should add a disclaimer that most of my listening through the GS3 has been done with the E7 - but i don't that signature wolfson warmth that i heard before and the treble is sibilant
[Galaxy S III General] TotallydubbedHD:
E7 doesn't count for this problem, please test via headphone out!
[Galaxy S III General] omersak:
What i'm trying to say is that i may not properly remember the sound out of the headphone out because i've almost exclusively used the E7!

I think it might be safe to say that 'that' particular crackling is gone. However, there are occasional pops when operating through the system with the screen on.

Needless to say, the E7 doesn't work in CM9.
[Galaxy S III General] knights.JayTana:
Im on Indie's build with r2, cant hear any crackling.

Anyway, those who are reporting with issues, can u try other Custom Kernel.
[Galaxy S III General] studiominal:
Maybe some users may have reported this issue already, and I really hope Samsung is working on it for the next firmware update. But guys, please do spread this issue over people around you who are using SGS3 and then we can be freed from this irritating noise much quickly.

Screen off AND USB disconnected - The most prominent conditions where random pop noise occurs regardless of music players apps. It lasts for a lot less than 0.5s but really irritating once you notice it. Only when either of the two conditions is broken, I mean when the screen is on or USB is connected, you may not hear it.

By the way, I will test if the voodoo sound driver could fix the random noise as soon as supercurio releases its prototype version.
[Galaxy S III General] ama3654:
perfect sound

Honestly i listened to so many soft tracks with screen off, and i dont hear anything, my earphones are quite descent and if theres anything i would've heard, only if there is a away i can play some music for everyone to check. Observation using stock player
[Galaxy S III General] knights.JayTana:
I contacted 2 of my friends who also got S3, they have no crackling issue... they were both @ stock DXLE9 and used the supplied ear buds.
[Galaxy S III General] studiominal:
OK I just got a reply from Samsung Korea regarding the random pop noise. They seem to have reported this to engineering department and said they'll get me the response as soon as possible.

Even now listening to music on my SGS3 with Sennheiser HD 650, I sometimes notice the noise seems to have gone away, but it still does happen unexpectedly. For those who want to know what firmware I'm on, I used to run XXALE9 and then flashed XXALF2. On both of which was there the noise.
[Galaxy S III General] omersak:
Moment of reckoning - Voodoo sound cometh:

http://xdaforums.com/showthread.php?t=1708763

Franco implemented some of it into his great kernel. we need someone to test this ASAP! i'm at work or i'd have been first in line.

EDIT: Just to clarify, it isn't THE supercurio GS3 specific voodoo: "This is not Voodoo, I just rebased a few functions from a very old Voodoo implementation, re-arranged and re-formated them, I need to clarify this or people will go berserk soon." - Franco
[Galaxy S III General] kanemari:
on it right now!!

as much as i know supercurio will get around to this (and i bought his paid voodoo app in anticipation of it coming) sometimes perfectionism frustrates the hell out of the plebs in waiting :p

EDIT: volume increase is very noticeable. quality not sure, but probably because i dont have any flacs or lossless audio to test with. have had a few random reboots though while tinkering with the software equaliser built into the stock music player. will stop tinkering and see if i have stability on the way home on the train...
[Galaxy S III General] TotallydubbedHD:
is it voodoo sound, or something like it, that's inside?

I'll flash it soon enough!

EDIT:

Problems include people not hearing phone calls - I'll stay away for the time being.
[Galaxy S III General] TotallydubbedHD:
Guys...

"ah we have that prob with the sgs on ics :) you need to raise the screen of min to 200mhz instead of 100 :D get set cpu and raise it from 100 to 200 or from 200 to 400 try it doesnt hurt"

[Galaxy S III General] gandalf027:
I am using the Paranoidandroid rom, and i had a lot of pops.

Set the min to 400mhz (was 200) and the pops are out :D

Going to get back to 200mhz and see if it happens again.

Good news :)
[Galaxy S III General] TotallydubbedHD:
hehe!

400mhz didn't work for me though.

1.4ghz seems to be doing the trick

EDIT:

Great news:

[Galaxy S III General] total.destroyer:
I just made a diy usb otg/data charging cable and tried to connect my Fiio e10 to it. The led comes on and i hear a pop in my headphones but no sound comes out. Is it possible because of my rom/kernel combination (on omnia 5.0) ? or the dac isn't getting enough juice, or it simply won't work with this model?
[Galaxy S III General] kurama.k:
That's amazing :) but won't running all 4 cores at 1.4 ghz drain the battery fast, also I think the wolfson chip that's in the SGS3 is supposed to use less power than the wolfson chip that's in the sgs1 :D
[Galaxy S III General] TotallydubbedHD:
See that' what I've been trying to ask curio about :p!

And yeah all 4 cores at 1.4ghz lol - battery didn't drain as fast as i thought

I'm back to 500 and testing.

more people testing the better.
[Galaxy S III General] studiominal:
For me, SetCPU is working like a charm in terms of eradicating the random pop noise. It's sort of ridiculous to see how the noise is gone when I pulled the minimum frequency up to 400MHz and then revert back to 200MHz(default).

As long as it's just a workaround, however, upgrading to a firmware that has fixed the issue or applying voodoo sound to your SGS3 will be the ultimate solution. Since there are bunches of people who don't even know what rooting is, I think the approach to the issue should be like the former - Official hotfix from Samsung :)
[Galaxy S III General] gandalf027:
Same happening here. Set to 400Mhz and then to 200mhz and it's gone.
[Galaxy S III General] goody_23:
is this on rooted handsets you are getting setCPU
[Galaxy S III General] taylord1984:
Not read all the post here so don't know if what I'm about to say is been said. Sorry if it has.

I had the sound problem with stock rom then switched to Omega_v4.2 and the problem was gone. Then updated to Omega_v5.1 and now its back. Not looked into the differences of the three as of yet. About to have a look now. Will share my findings.
[Galaxy S III General] TotallydubbedHD:
indeed.

On CF root, but this also happened on STOCK, no root apparently.

please do so - seems power related.
[Galaxy S III General] danba:
If my theory is correct, it won't work, because the FiiO E10 contains a USB controller Tenor TE7022.

The SGS3 may interwork with the USB DAC/amp FiiO E10 via a powered High-Speed / Full-Speed USB 2.0 hub.

For the moment all USB DAC with known USB controller, which interwork with SGS3, contain a Full-Speed transceiver:

. AMB Labs Gamma2 with USB controller TI Burr-Brown PCM2707

. FiiO E7 with USB controller TI Burr-Brown PCM2706

. Go-Vibe Mini USB DAC with USB controller TI Burr-Brown PCM2702

. HifiMan Express with USB controller TI Burr-Brown PCM2702

. iBasso D12 with USB controller TI Burr-Brown PCM2906B

. Topping TP30 with USB controller TI Burr-Brown PCM2704

The following USB DAC with known USB controller, which don’t interwork with SGS3 for the time being, are:

. FiiO E17 with USB controller Tenor TE7022 (FiiO E17 does work with Android-powered Archos G9)

. iBasso D6 with USB controller TI TAS1020B

. Grant Fidelity TubeDAC-11 with USB controller Tenor TE7022

SGS3 Full-Speed / High-Speed switching issue?

http://www.gfec.com.tw/TE7022L

http://www.ti.com/lit/ds/symlink/pcm2706.pdf

SGS3 USB driver issue?: some parameters are not well-adjusted?

"The host controller directs traffic flow to devices, so no USB device can transfer any data on the bus without an explicit request from the host controller. In USB 2.0, the host controller polls the bus for traffic, usually in a round-robin fashion. The throughput of each USB port is determined by the slower speed of either the USB port or the USB device connected to the port."

http://en.wikipedia.org/wiki/Universal_Serial_Bus

Powered USB 2.0 hub containing Full-Speed and High-Speed transceiver workaround?

http://www.ti.com/analog/docs/microsite.tsp?sectionId=590&tabId=2211&micrositeId=11

"High-speed USB 2.0 hubs contain devices called transaction translators that convert between high-speed USB 2.0 buses and full and low speed buses. When a high-speed USB 2.0 hub is plugged into a high-speed USB host or hub, it will operate in high-speed mode. The USB hub will then either use one transaction translator per hub to create a full/low-speed bus that is routed to all full and low speed devices on the hub, or will use one transaction translator per port to create an isolated full/low-speed bus per port on the hub."

Anyway, dmesg log output and lsusb log output could detail what is going on.

[Galaxy S III General] taylord1984:
I cant work it out. Maybe it is a power problem as all of roms used was a different kernel with different voltages(I think?). I cant change kernel as not got a windows pc.

Did some tinkering on Omega_v5.1

Got setcpu on

1400max 200min

governor ondemand

scheduler sio

Not had any staticy sounds for ages.Only change is the scheduler from cfq.

Edit so maybe a bug in the scheduler cfg? what is every one else using?

Surely the HD650 headphones cannot be driven by the S3?
[Galaxy S III General] ma10:
I just received NwAvGuy's ODAC in the post today, just tested it along with the O2 amp and it is confirmed working on the S3:

@danba, not sure if this throws a spanner in the works but I believe the ODAC uses a Tenor TE7022 USB controller.
[Galaxy S III General] TotallydubbedHD:
It won't be able to fully drive it, but listening to low volumes, shouldn't be a problem, like listening to my PFE232's or D2K's

sweeet!

EDIT:

Been doing some more tests.....and I think that min cpu freq has something to do with it.

When moving higher, ie. im at 500 now, the frequency at which the noise comes is reduced.

I'm constantly moving up to see when I won't hear it no more.

I could be wrong, but that's a theory.
[Galaxy S III General] studiominal:
Stock S3 can drive HD 650 at the comfortable level for me, but I guess it would not be loud enough for many people. However with Voodoo Sound, volume can be massively boosted enough to blow your ears out. More options like 128x oversampling, Anti-jitter, and DAC direct are to come, say, within this week :)

If you're talking about some damping or something, yes, GS3 still is capable of driving most of hard headphones because it's got low output impedance. Listening was the first I've done to check it out though. :D

---------- Post added at 09:24 AM ---------- Previous post was at 08:46 AM ----------

You were right that I should reboot my device to get the noise back :) After ticking some options in SetCPU (as I mentioned in page 42) I noticed the noise was gone, but the battery drained much faster during last night. Taking a look at the battery usage on my phone, I just noticed that my phone turned itself on while I was sleeping! (not screen, I mean 'Awake' on battery history details) But there was no SetCPU on the list of applications which ate up the battery most.

At this stage I can't confirm any of what I've found so far, so I'd better return to the very beginning, and then iterate the procedure. One thing I guess is that it might have something to do with the scheduler, not the CPU frequency itself because I checked if the CPU frequency changes significantly if I plug the USB cable into my SGS3, or turn the screen on. No change.
[Galaxy S III General] fc4ever:
yes, quality of sound in s3 is realli not that good.
[Galaxy S III General] goody_23:
I think it is very good it just needs some tweaking that's all..
[Galaxy S III General] Kendoji:
Yeah sound quality is great. I only noticed a pop yesterday, but that probably says something about the kinds of music I generally listen to.
