[Xperia Z1 General] KWOKSFUNG:
If u guys are serious in music playing, u may found that the Z1 usually got some terrible static noise in the background during music playback, especially if u use flac file. (damn even older xperias dont have such stupid problem!! hate it right??)

U may flash dreamingonmusic for better quality, but it wont really eliminate all the noises.

I guess that the noise was made because our CPU arent captable to process the music at the default volume requested by the kernel. But since it's forced to do so, it wasnt done so well and noise was made

(I'm not saying the volume we normally control by pressing the +/- button. It's believed that the max volume you can get was requested by the kernel, then u pick a volume between mute and the given max value)

So what do we have to do?? That's to turn the max volume lower!!

*Custom kernel might be required*

Steps:

1. Open Pimp My Z1

2. Sound Control

3. Turn "Headphones Digital Gain" to a value below zero. (A value that's suitable for you)

The volume will become significantly lower by then, the lower the volume the less noise there will be.

Since everyone needs different volume, i cant tell which one you should get. But at least you can get to a volume that you'll actually need.

Well I know many of you claim that the stock volume is already too low and u guys have to boost it with the mixerpath. This method may not suit you then.

This method is actually discovered by [MENTION=5191347]Chocolatetrain[/MENTION] , thank him if you find it useful :)

When the hell will Sony give us a dedicated audio chip?? HTC got it and Samsung got it!!

Come on Sony starts up their business by Walkman!! So they really want to give us such crap on the "Best of the Sony in an Xperia smartphone" ??
[Xperia Z1 General] Chocolatetrain:
Nice guide, also, I'm pretty sure it's not the CPU, it's the amplifier, which in our case, is fairly low quality compared to other flagships or maybe even some mid-range phones. ;)
[Xperia Z1 General] KWOKSFUNG:
Is it? I thought sound was amplified by CPU as well since we dont have the legendary s-master chip
[Xperia Z1 General] Chocolatetrain:
Not sure tbh, just a guess lol ;)
[Xperia Z1 General] zigory:
CPU cant generate noise...

It may be generated betwen Hexagon DSP (trought the amplifier) and headhone output. I bet on amplifier too.
[Xperia Z1 General] KWOKSFUNG:
Wait bro could u explain a bit more?

I thought everything was done by CPU since we dont have dedicated sound chip.

Sorry i'm a noob
[Xperia Z1 General] zigory:
Most of snapdragon SoCs have the DSP co-processor which one of it's tasks is to handle encoding digital stream to analog signal. However audio data is processed by the ARM CPU, not dedicated audio chip. Interference may bring on way from Hexagon (where signal is weak) to amplifier. Also amplifier can add something bad to headphones ;)

simple example

CPU>Hexagon>Digital to-analog (DAC) converter>Amplifier>audio output
[Xperia Z1 General] KWOKSFUNG:
Maybe that's why flac got more noise then aac since it's more complex codec?

btw is it possible to reduce the noise by software method? maybe identify the noise and eliminate it before audio out?
[Xperia Z1 General] zigory:
It's strange but I didn't notice any huge noise on lossless codecs were it will be bigger than non-lossless. Maybe you have ****ty FLAC files with recorded noise or player have bad libs or your device have damaged amplifier. It shouldn't matter what data is processed. What player do you use?

And FLAC is simplest than AAC, it's only carry more data and it's real-time decoded (unlike AAC).
[Xperia Z1 General] KWOKSFUNG:
I use Walkman player with dreamingonmusic mod

I'm thinking maybe the flac files I got sucks becoz they are encoded by people who bought the disc and AAC might be higher quality becoz they are official version encoded by iTunes.

(well I'm those bada** who keep download and never perchase a disc.)

But seems I got zero noise no matter AAC or flac after I lower the kernel volume gain
[Xperia Z1 General] taranfx:
sorry OP but i've audiophile grade headphones and i dont hear any hiss. Sound is crisp and quiet good, just like samsung flagships. I use stereo speaker mod, it increases headphone volume too. Even at high volumes theres little to no hum while playing FLACs with PowerAMP.
[Xperia Z1 General] richmaster1o2:
Doesnt work for me
[Xperia Z1 General] KWOKSFUNG:
Good for you.... actually the noise is most obvious in the silent part of songs. It wont really mute on those part but some s**tty noise might be made. Yes, the noise seems much less significant if u use headphone with high resistance. Or maybe your headphone is so good that it can cancel noises.

Btw EX650AP is my primary earphone for this phone and I'm pretty sure this method cancel most (if not all) noises i heard in silent part of music
[Xperia Z1 General] KWOKSFUNG:
U on stock kernel?
[Xperia Z1 General] Tikaroz:
Won't it like, decrease anything else?

Cause that noise is driving we crazy sometime.

And it worse when I increase bass, clearity, etc.

Ps.I thought I was the only one having this problem cause in samsung

It doesn't have this "thing".but, the sound quality is not so good
[Xperia Z1 General] KWOKSFUNG:
So samsung actually has worse quality in music but it got no noise?

yea i was also pretty disappointed in the music when i first got the Z1. Need audio mod to reduce it before (even it doesnt kill them all)

Sometimes i really get mad when i hear those "shilishaglag" sound.

Seems to be the problem of the amplifier. We were supposed to be given with S-Master Amplifier but they cut it off in the final product.

Maybe sony mis-calculated it will cause noise

sucks to be guys who dont root or use custom kernel
[Xperia Z1 General] Tikaroz:
Camera is the first thing in sony that doesn't get mess up with hardware itself

(well, instead we got the the software to mess it up for us anyway..you know [over-compression])

Orther than that they just pretty much rune everything

Good screen with yellow hue and touch problem.

Nice hardware on board with vibration issue

Out standing sound quality with weird noises, etc.

I hope Z4 will turn out good cause I really like their firmware and sony xda forum.

A lot of thing to mod
[Xperia Z1 General] KWOKSFUNG:
Exactly what i think

I really cant get what those guys in xperia software department are thinking :confused::confused:

Xperia Z1 is so under performed without mods

btw i really think they should add a better amplifier if they insist to produce such loud sound in earphone mode
[Xperia Z1 General] Tikaroz:
They might have done something good with Z3 already cause I heard the only "WoW!" thing is

The new chip for sound enhancement

But I won't get this one expensive device that should have been called "Z2"

They should just release flagship every year and that's it.

I'll wait for Z4 or Z4 compact.

Will not give up on them yet.
[Xperia Z1 General] KWOKSFUNG:
wait wait there's finally dedicated audio chip??

is that true?

Calm down.... I'll use the Z1 for 1 more year at least
[Xperia Z1 General] Tikaroz:
My bad, that was a leak

http://au.ibtimes.com/articles/5653...lusive-features-available-z2.htm#.VBH2CHButmc

This is the official one

Now it has 3 features just for sound

DSEE HX, Hi-Res Audio and Digital Noise Cancellation.

S-chip won't come to xperia anytime soon, I think
[Xperia Z1 General] KWOKSFUNG:
Ok, there's still probability to port all the 5h1t (except DNC) to our Z1 :D:D

(or is it possible to port DNC someday??)

I'm happy now

Well next time i may leave Xperia family if they cant bring something that's really cool
[Xperia Z1 General] Tikaroz:
dontbelive has ported the first feature already, try it out :cowboy:

[Xperia Z1 General] KWOKSFUNG:
lol I installed it few days ago

pretty good, voices feels much thicker now
[Xperia Z1 General] Tikaroz:
Which version have you use?

Mono or Stereo?

Mine speaker acting weird after using stereo.
[Xperia Z1 General] KWOKSFUNG:
i use stereo myself but yes thats pretty weird

the speaker is limited from being vs optimized becoz the earpiece will crack very easilly when u touch low freq sound

stereo has its advantage, but its too strange since the earpiece cant perform well (as isnt supposed to) and it gives different sound compared to the speaker. I'm thinking about moving back to mono.
[Xperia Z1 General] olokos:
I never had any issues with any noises and I have an album full of flac songs and they are played perfectly fine, without any noise.
[Xperia Z1 General] KWOKSFUNG:
Are u using earphone that has high resistance?? coz it seems to be less noticible on high resistance earphone

http://xdaforums.com/xperia-z1/themes-apps/true-real-stereo-sound-earpiece-t2822691

Anyone have used both of them can give me a review, compare between them?
[Xperia Z1 General] KWOKSFUNG:
DOM is more focused on optimising the headphone experience while stereo mod aim to make stereo with the earpiece and the speaker

if u use stereo mod, u may experience a bit more noise on headphone (as u know we have bad amplifier so maybe a bit hard to push it well)

Well since headphone can always be better than the speaker(with earpiece), i use dom

but stereo mod usually do experiment on the speaker( with earpiece) and it's pretty fun becoz sometimes there's surprise on the performance the earpiece.

(I havent tested the newest v10 of stereo mod yet, not sure if good or not but)
[Xperia Z1 General] olokos:
Koss PortaPro's that are 60 Ohms, but I didn't have this issue even with stock earbuds.
[Xperia Z1 General] KWOKSFUNG:
Oh lucky u

My main headphone is MDR EX650 AP which has 16ohm (will definitely feel the noise normally)

will also feel it on stock mh750 or mh650c

seems to be no noise on XD150
[Xperia Z1 General] E620se:
I have no static noise with the Z1 and my Ultimate Ears Triple.Fi 10 (32 Ohm).

On a previous firmware (I guess 4.3) I had this background noise directly after plugging the headphones in. It disappeared after a few seconds. Now with 4.4 it's gone completely.
[Xperia Z1 General] KWOKSFUNG:
Yeah there seems to be less noise on newer firmware, but i still feel there's some

maybe each of us have slightly different hardware??
[Xperia Z1 General] E620se:
Maybe, but as I said, on previous firmware version there was noise.

There was really loud noise for a few seconds.

Now on 4.4.4 there is no recognizable noise anymore.
[Xperia Z1 General] KWOKSFUNG:
for me, it's less noise on 4.4.4 but there's some still here (noticible for me at least)

since i know that the min volume in 4.2/4.3 is higher than that in 4.4.4, i'm pretty sure sony decided to turn the kernel volume a bit lower by deafult = =""

I think your connection is configured as "always on". You can change it in the registry....

Indeed, or if you're not confident about changing registry use something like Tweaks2k2 to make the change for you along with lots of other little tricks.

[8525, TyTN, MDA Vario II, JasJam General] drbrains:
You could try a less drastic approach:

Check:

Settings, Connection-tab, Connections, Advance-tab.

(hope this is correct, I don't have an english rom-version)

There you should be able to select which connection is automatically used. I have this on T-Mobile default connection since I have an unlimited dataplan and use direct-push.

When using the phone as modem, I have to switch this "off"/different setting eg. work connection to avoid conflicts.

Hope this helps
[8525, TyTN, MDA Vario II, JasJam General] MikeChannon:
We like drastic, drastic is sooooo gooood!!

Seriously though the originator does not say he does not want to use GPRS only that he does not want it starting automatically. So the connection type maybe correct only it needs its bottom smacked for running off without daddy. We have ways in the registry to control such dis-respectful behaviour and baby Hermes must be punished or else get sent to bed with no active sync with Mummy.

[T-Mobile Samsung Galaxy Note 3] sixk:
Hey guys specially those who are using their phones on the ATT network.

What is a good 4.4.4 ROM that I can use with minimal issue?

Looking for a ASOP feel but looks of the TW. (but can be customized and themed)

Any suggestion is appreciated.

:good:
[T-Mobile Samsung Galaxy Note 3] sixk:
Noone?
[T-Mobile Samsung Galaxy Note 3] Anonymously_Unknown:
I know what you are saying, but it is still conflicting. You really can't have them both. True AOSP will not support the framework for the sPen. Leaving out the TouchWiz framework (not just the launcher) cheapens your Note3 down to a boring Nexus device. A Note3 without the functionality of the sPen might as well be a paperweight or a boring non-Samsung device.
[T-Mobile Samsung Galaxy Note 3] quickbird144:
I have to agree. Of course many will have their own opinions and there are AOSP and TouchWiz ROMs for whatever you prefer, but to me AOSP is half and half. Great features, but lacking some other things obviously as a AOSP ROM is a few hundred mbs while a TouchWiz ROM is a gig or two. I run Vision X on my Tmo Note 3 and I'm on ATT network. No problems, fast ROM, and awesome battery life and I still have all the features of the Note.

Thanks will give that one a try haha.

Also are you using the Tmo version or the international version?

Can anyone help me please!!!!!!!
[Galaxy Tab 2 Q&A, Help & Troubleshooting] BoneWithABeagle:
You are not reading what you are typing.

Obvious answer: If you end up in the STOCK RECOVERY you simply do not have a custom recovery installed (Clockworkmod as you wrote). Get yourself a copy of a recent recovery from AndroidAndi's download repository (TWRP, Clockworkmod Swipe, PhilZ Touch), and flash the .tar.md5 of the recovery with ODIN in download mode.

Obvious question: How did you flash a ROM, other than some OTA Stock Samsung update on the device itself, in the first place when you don't have a custom recovery installed in order to do so?

EDIT: What exactly do you mean by "factory reset"? Did you re-flash your tablet with a Stock ROM? If that's the case, then any custom recovery you had installed was wiped and replaced with the stock recovery. Hence why you now don't have a custom recovery anymore.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] yolo squad dodo:
Odin won't recognise my tablet in Odin mode neither does my computer is there another to install a CWM recovery. By the the I do have back up on the phone if that helps.

By the way I am a noob
[Galaxy Tab 2 Q&A, Help & Troubleshooting] BoneWithABeagle:
Just to recap on the steps you should have done...

1. You downloaded the .tar.md5 of the recovery you want to install, from Android Andi's filehost, on your PC

2. You installed the Samsung USB drivers on your computer

3. You installed ODIN on your computer

4. You unplugged the tablet from the charger and powered it off

5. You took your tablet and HELD VOL-UP while you powered it back on (to get into bootloader mode)

6. You plugged the tablet in to the computer and waited for a moment while Windows was installing the driver

--- Here the story ends, according to what you wrote as you say ODIN does not find the tablet.

Well, are you sure you did the steps so far in that order? Can't be that ODIN doesn't detect the tablet when it's operational (read: no a total dead brick) and it's in download mode.

The ONLY problem possible: You installed Samsung KIES, and not just the USB drivers, on your computer. KIES interferes with ODIN. You need to exit ODIN, bring up the Task Manager (press CTRL+ALT+DELETE and select "Task Manager"), find "kies" and end the running process(es) - ignore any warning message.

If that's too complicated: Uninstall KIES and then find the "Samsung Mobile USB drivers" installation package ... with a bit of searching (just to assign some homework to you) you will the links right here in this forum section more than just once.

Once KIES is terminated, or uninstalled and just the USB drivers installed, start ODIN again ... now it should detect the tablet.

Once ODIN confirms that the tablet is detected...

7. Select the .tar.md5 of the recovery as the "PDA"

8. Flash the recovery. Once complete the tablet rebooted into the newly installed recovery.

As for on-device flashing. That's possible...

- Your installed ROM must be ROOTED (no root, no fun)

- You need Chainfire's "MobileODIN" (the free version from the Play Store would suffice), and you need to let MobileODIN install the "p311x flashkernel package" (I think with the free version you need to download it manually from Chainfire's thread and install it manually) - jump into Chainfire's thread and read on

Once you have Mobile ODIN installed it is just a matter of:

- Download the .tar.md5 of the recovery on your tablet once more (or transfer it over from your PC)

- Start Mobile ODIN

- Select the .tar.md5 of the recovery (should automatically be set as a "PDA")

- Flash and reboot into the recovery

However, as a fair warning ... as with every flashing of your device ... keep in mind something could go wrong (just to straighten it out that there's always room for user mistakes or murphy's law getting into the way ("Everything that can go wrong will go wrong";)))

Thanks a lot by the way for the tips
[Galaxy Tab 2 Q&A, Help & Troubleshooting] BoneWithABeagle:
For future reference: keeping VOL DOWN UP held while powering on/rebooting the tablet takes you into the recovery in case you borked the system and selecting "Reboot" -> "Recovery" from within the _custom_ ROM's power menu is not an option (the Stock Samsung ROM does not have that option by default). Though keep in mind that this only works when the tablet is _NOT_ connected to the charger/computer ... when the USB cable is plugged in it seems to ignore the hardware keys.

Great you got your recovery and custom ROM installed. Have fun.
