I spent about an hour and a half researching this so far, but I can't find a clear answer since the information is so spread out.

I'm running a T-Mobile GSIII on [ROM][4.2.2] AOKP MR1 Kang Project - d2tmo. I have the option to turn dock audio on within Device settings, but the audio keeps coming out of the phone speaker.

What is the easiest way I can get this working? If there's a specific ROM or kernel I need to flash, what it is?

Thanks!
[Galaxy S III Accessories] CZ Eddie:
It's only available on a couple AOSP 4.1.X ROM's and stock 4.1.1 stock ROM's right now.

None of the 4.2.X AOSP ROM's are working with this yet.
[Galaxy S III Accessories] zinite:
CM10?

JellyBam?

Any tips are appreciated.
[Galaxy S III Accessories] themadproducer:
Works on my Stock ICS but when phone rings, media stream skips until dialer is closed.
[Galaxy S III Accessories] CZ Eddie:
For the 4.1.X AOSP ROM's, only LiquidSmooth and Xylon work. If you can find them anymore. All stock based/rooted ROM's work.

LiquidSmooth ROM never skips, it had flawless audio performance. But you lose the headphone jack on LiquidSmooth. And the 4.1.X Xylon ROM was a WIP ROM with various bugs.

The 4.1.2 LiquidSmooth ROM was fantastic. Never once had any cd-skipping type sounds. Sounded excellent and was a flawless, bug-free ROM. Perfect if you didn't need the headphone jack, which was the only issue. BUT, I can't find that ROM download anymore. I have a nandroid and if someone bugged the hell out of me, I might be talked into uploading it. But it was a nandroid from a dirty flash so I can't guarantee it will work perfectly.

Stock ROM's skip sometimes when initially connecting audio and also when taking calls or other events occur. Otherwise they work great.
[Galaxy S III Accessories] CZ Eddie:
Yeah, until 4.2.X AOSP ROM's start working with USB-DAC's again, I've decided to go another route.

APT-X Bluetooth.

Sounds better than headphone, analog USB and regular Bluetooth.

Does not sound as good as USB-DAC, but it's close enough.

The only problem is with finding an APT-X receiver that is turned on 100% of the time. I got a Saturn receiver and plugged it into my car stereo and made sure it had an always-on USB power connection. But the stupid thing turns itself off after a couple hours.

But, it does connect semi-quickly.. And if as mfg's start giving us more APT-X receiver options, we may find one that works well for us. MFG's are also working on bluetooth latency issues these days as well. Google "APT-X Low Latency" for more info. Not sure if that means it will connect faster or just give quicker response after it connects.
[Galaxy S III Accessories] themadproducer:
Sounds good.

Please let us know if you or anyone...finds an APT-X BT that stays awake with full time power.

I am not familiar with this connection.

Is it a BT receiver that you plug into AUX in of the car Stereo?

Could you give me a description. (be as detailed as you like)

Thanks CZeddie
[Galaxy S III Accessories] CZ Eddie:
Yep, you plug an APT-X qualified Bluetooth receiver into the AUX input on your car stereo. Then you pair the phone with the Bluetooth receiver. It works pretty well. Music audio from the phone goes to the car stereo's AUX input. Phone does not need to be docked.

Phone call-audio still works through normal Bluetooth on the car stereo.

Alienz says he has a working solution already. It just requires an extra component for volume increase. My Saturn device doesn't need any volume assistance, but it does turn itself off after a couple hours (of non-useage) which is annoying. So if I'm away from the car for a couple hours, I just have to press the power button one time on the receiver. No big deal. But a small annoyance I'd rather not have, since it means I can't hide the receiver behind my dash. It needs to be within arms reach so I can turn it on every morning.

Here is the Saturn I just got:

[Galaxy S III Accessories] themadproducer:
Thanks CZeddie.

Is the Saturn capable of transmitting phone call audio as well?

I am guessing not.

What I do like about using the headphone out, is that I can answer a call through my car stereo...if I don't have my BT earpiece with me, or charged or if it is out of reach. So I can manage a short call on the stereo speakers or even switch on my BT earpiece and it takes over. So I am wondering if the Saturn can do the same.
[Galaxy S III Accessories] CZ Eddie:
Nope, the Saturn is music-audio only. No phone-audio options available.

But when a call comes in while I'm listening to music with the Saturn, my phone & car stereo both automatically switch over to normal Bluetooth. So there are no problems with taking calls on my end. I don't use any earpiece things, so I can't comment on how well those will work?

Thanks for the information so far. I'm actually unable to find any reference to a v3.2 of 4.1.2 LiquidSmooth.

Here is an example search that I used to try and find the ROM you're referencing. It's not coming up with anything. I understand you said you can't find it - but is it possible that you have the version number wrong?

You remember that SoundAbout app I mentioned?

There was an updated today...ohhh and it comes so close to fixing my audio stream issues. I don't have the time to test this wknd because I am away, but it gives promise of hope!

I am glad I have not installed my CraigsDock yet. I will have to try to contact the dev about it. In pieces, I have seen everything work. It just needs to be refined as a whole. There are various scenarios that may cause the audio routing to not switch properly as I have just witnessed. STAY TUNED.
[Galaxy S III Accessories] CZ Eddie:
TheMP, hope that works out for you!

I made a great breakthrough with the APT-X stuff today.

$55 OTD from Best Buy.

Splice a USB cable.

Audio + Dock + Car Stereo ---everything is working great together finally, and I get to keep my AOSP ROM's. I just set it up though, so I'll wait a few days to test out the kinks before I start a thread on it.

Sorry guys, I just tested the 5/5/13 release of LiquidSmooth and USB-DAC functionality is still NOT working yet.

I'm able to plug my phone running the 5/5 release into my car setup with a Behringer UCA202 and have it work - is this different than what you're talking about?
[Galaxy S III Accessories] CZ Eddie:
Well, yeah... the UCA202 is what I have also.

But I'll be darned if I can get it to work.

I'm on the 5/5 LiquidSmooth "Official" release with the stock kernel that comes with it.

I get no audio output when connected to my UCA202.

And my USB port gets disabled if I attempt to reboot the phone with the UCA202 plugged in.

Glad it's working for you though! :good:
[Galaxy S III Accessories] themadproducer:
That is definitely usb digital out.

Tell me zenith, if you have an incoming or outgoing call while using your uca202 and listing to power amp, or YouTube etc, what happens?

I have full control over the phone from the touchscreen in the dash. Phone sits in a compartment while driving. It doesn't slide or fall out while driving because of the rubber inner part of my case.

The phone charges when connected through mhl?
[Galaxy S III Accessories] Soupskin:
Yes. It's connected to the proprietary Samsung MHL adapter that is necessary for the S3 and Note 2. Both of them have an 11 pin MHL port as opposed to a standard 5 pin. The other end of the adapter has an HDMI port and a micro USB port for charging. I have a high amperage hard wired micro USB charger behind the dash that is plugged into the adapter. The charger is able to power the adapter and charge my device with GPS, streaming media and the screen on all the time. The only other "odd" thing involved is the parking brake relay that simulates the parking brake being applied, released and applied again in order to display the HDMI video source on the screen.
[Galaxy S III Accessories] Zero722:
I'm looking for some advice. I'm currently playing music from my phone through my car using a bluetooth FM transmitter (specifically this: amazon (dot)com/Motorola-Bluetooth-Portable-In-Car-Speakerphone/dp/B0030BZ7HM). I know I'm probably getting the worst quality possible. My '03 Prius doesn't have an AUX in, so I've been very limited in my options. I've read through this thread, learned a lot, and am thinking about trying this setup:

I want to try to install the iSimple IS32 (amazon (dot)com/iSimple-IS32-Universal-Integration-Smartphones/dp/B004613FCE/ref=pd_cp_e_0) that pitcherj mentioned earlier to give my car an AUX in port. Then hook up something like this Bluetooth Apt-X receiver (amazon (dot)com/Kinivo-BTC450-Bluetooth-Hands-Free-Input/dp/B009NLTW60/ref=sr_1_1?ie=UTF8&qid=1372689831&sr=8-1&keywords=aptx+aux+in)

I don't care about ugly wires or anything like that, mostly just trying to get really good sound quality. You guys seem to be avoiding plugging from headphone out to AUX in directly. Is this for audio or aesthetic reasons? Is this a good solution or is there a better/easier/cheaper solution for me?

Additional info: I have a Galaxy Note 2, rooted but stock OS, and I've installed the Viper 4 android sound mod.

CZ Eddie, I'm like you. I've been waiting for a stereo dock with bluetooth apt-x to come out. I can't believe there still isn't anything.

*Edit: eff, still can't post links yet
[Galaxy S III Accessories] OnTheEdge:
In theory a true "line out" will provide better sound quality than the headphone jack ever can.

In practice, it seems different for every situation. In my car, I actually have two AUX jacks (one built into the stereo and one as part of an aftermarket iPhone adapter). They each sound different when used.

I use my headphone jack to the aftermarket aux in and I feel it sounds great, but every listener has to make their own decision.

The problem is that you can't ever really know until after you invest time and money into some sort of "line out" out solution so that you can hear both options in your car with your phone, and then most people convince themselves it is better, since they spent the money and time. Or they post a glowing review ten minutes after they do it, and then quit using it a week later but don't tell anyone.

I'm also not happy with the need for an external DAC, which adds another variable. The DAC itself could end up being worse than what is inside the phone. The later Samsungs (Note II, Galaxy 3, and later) have very good DACs built in.

However, it sounds like your first job is to get a proper AUX in on that car anyway. I would look into aftermarket options. there are a lot of products for cars that just plug right into the back of factory stereos to provide a very good AUX jack.

Then you can play with "headphone out" vs. "line out".

EDIT: P.S. I just looked at that iSimple you mentioned. Too bad it still uses FM, but it sounds like the '03 Prius doesn't have a lot of options for some reason. The unit I had for my car hooks into the Satellite radio plug, so it is very high quality. (It sounded awesome with my iPhone) That would give you an AUX port though, but I'm thinking it would still be limited to FM radio quality, wouldn't it? Maybe just less "fiddly" than a transmitter and more reliable?
[Galaxy S III Accessories] Zero722:
I was thinking FM radio quality comes from the wireless signal, not from the physical antenna connection. The iSimple would physically connect to the FM antenna to make use of that input (I imagine it's almost exactly like the old RF modulators of the NES days). So I imagine that the iSimple would have superior quality to the actual FM radio. I could be completely wrong though; I know next to nothing about all this stuff.

Is bluetooth apt-x more like a true line out than a headphone out? I'm wondering if there's value to using a bluetooth apt-x adapter over just plugging directly into the aux in from headphone out.

Update: Did a little more research. Seems other Prius owners have been adding aux inputs using the CD changer input. It seems even the standard stereos come with the port even if they're only a single CD stereo. It also seems using this input yields higher quality than using an FM modulator (seems the modulator does create a loss of quality). Fun fact: you have to remove EIGHT dash panels to get behind the stereo in a Prius....
[Galaxy S III Accessories] jasonbtx:
International S3 has Wolfson dac= good. US S3 has Yamaha dac=bad. FM modulator compresses music=bad. At least thats how I read it.
[Galaxy S III Accessories] xdstx:
Are there any AOSP roms that still support USB DAC? I'm on d2vzw but I'm willing to downgrade just to get USB DAC to work T.T. Using OTG-Y adapter with FiiO e17

Not that I know of. I tried CM and it didn't work. Went back to Beans.
[Galaxy S III Accessories] dan04103:
Op thanks for this mod. Much improved. Dandroid/faux/acid with the external DAC is a perfect combo for the i747. Cheers!
[Galaxy S III Accessories] nbaj2k:
I've followed this for awhile when I had the S3, but never pulled the trigger. I recently received the S4 as a warranty replacement.

Would this have the same benefit with the S4? I purchased the new Mountek Snap Magnetic mount (the mounts to the car CD player) and I think this would be perfect.

I was hoping when I get into the car to use this, to only need to plug 1 cable into the actual phone (MicroUSB) that would take care of the audio and charging, and not have a need for using the 3.5 connection.

If anyone has any thoughts or could provide any input that would be greatly appreciated! I currently have stock S4, but am looking to switch to an AOSP ROM in the future (after the Safestrap workaround is finalized)

Thanks!

-J
[Galaxy S III Accessories] CZ Eddie:
I have the S4 now. I went ahead and tried the Behringer DAC on my AT&T S4 just now with Slim Bean AOSP 4.3 and it worked great.

Yes, you'll get benefits using the external DAC over the internal Samsung DAC, which isn't all that awesome in S3 or S4.
[Galaxy S III Accessories] nbaj2k:
Thanks for the reply! So just to confirm, this would strictly use the MicroUSB slot of the phone( for both audio and charging) and not the 3.5? Does charging work well? I currently have the stock ROM so hopefully it would work well with that.

I was hoping to plug into the Aux of the stock head unit in my Accord, but does doing that lose any of the benefits? I'm hoping to not have to pop open the head unit if I don't have to.

Thanks again! Am looking to possibly place an order for this tomorrow.

-J
[Galaxy S III Accessories] CZ Eddie:
Yeah, when I had my S3, the charging worked great after I set it up with the right type of cable. Which I'm sure I detailed in my OP somewhere.

It would work identical in the S4 with the exception that the S4 can handle a higher rated charger. 2A in fact, which delivers almost twice the charging rate than the S3 could handle.

I dunno. I'm sure it does but I'm not going to flash back to stock just to find out. :D

But typically the AOSP ROM's are the only ones that have trouble with USB-OTG and USB-DAC.

As long as the Accord head unit has decent circuitry on the AUX-input then it should work the same as any other head unit's AUX input.

Use a decent shielded dual-male RCA to single-male 3.5mm cable for the connection.
[Galaxy S III Accessories] nbaj2k:
I bought all the parts and after receiving them in the mail today was all excited to try this on my S4. I checked 'audio output' mode under 'Accessory' and tried to play some of the music on my phone. For some reason the any audio file does not play. (I'm using the stock S4 Rom).

I get the error ' Couldn't play the track you requested' when trying to play a file in Google Music, and when trying to play any file in PowerAmp, it stays on 0:00 and never starts. I even tried the same with YouTube and videos don't even play until I unplug it. As soon as I unplug the OTG, everything plays fine out of the phone speaker.

This is definitely frustrating. Does anyone possibly have any suggestions how I could get this working with my Galaxy S4? Now that I have everything, I'm not sure what else to try, unless somehow the OTG I bought from Amazon is faulty.

The phone it looks like doesn't charge with it since the cable doesnt seem to go in all the way. I figured that this shouldn't matter though and that even without the car charger plugged in it should still work

Any thoughts would be greatly appreciated.

[Galaxy S III Accessories] jgqb16:
This is incredible but I could never do it
[Galaxy S III Accessories] CZ Eddie:
That's weird. When I was testing ROM's that didn't work with USB-OTG, the music ALWAYS played. You just couldn't hear anything. Never once did I get any errors.

No, you don't have to be charging. But if your cable is capable of both USB-OTG and charging (some cables are) then I would be worried that it is not charging.

I know for a fact this setup works on S4 using an AOSP ROM, at least the 4.3 SlimBean Beta 5 ROM. I have not tested stock ROM.
[Galaxy S III Accessories] nbaj2k:
The OTG I bought doesn't seem to allow the charging cable to be plugged in all the way so I'm not sure if it's making a connection. But either way the phone is plugging in fine. Could the OTG maybe be effective? I'm trying to figure this out quickly in case I need to return anything.

If you have any suggestions I'd greatly appreciate it!

Worst case scenario, if I'm not able to get the DAC to work, is there such thing as just a MicroUSB cable that will allow me to plug in a car charger to charge the phone and also have a 3.5 mm connection for an aux so I can plug it into my car? My goal is to just have 1 wire coming out of the phone. (so I don't have to use both the MicroUSB and aux plugs)

Thanks,

[Galaxy S III Accessories] nbaj2k:
My hope is to get the DAC working with my S4 (although that hope is unfortunately fading). If not, this looks like it could work perfect. I'm guessing the usb end would just go into one of the cigarette adapters to charge?

With this cable, would I have to still turn on the 'Audio Output' mode under the Accessory menu?

Canicula, do you have this working on an S3 or S4 and are you using a stock ROM by chance?

If anyone else has any ideas on how to get my S4 working with the OTG and the DAC that would definitely be preferred.

Thanks!

UPDATE : I was looking around online and haven't found one of those cables that someone has had success with on their S4 (only their S3). Not sure if anyone that knows for sure of one that works with the S4
[Galaxy S III Accessories] CZ Eddie:
Confirmed, S4 with stock AMDL ROM does not work with Behringer USB-DAC. Just tried it. There may be other DAC's it works with, I dunno. You'd have to check the USB-DAC mega thread on that other forum.

But S4 did with with USB-DAC on SlimBean 4.3 AOSP ROM.
[Galaxy S III Accessories] CZ Eddie:
That cable is for analog USB audio output. iBolt sells one.

The same cable would work for S3 or S4.
[Galaxy S III Accessories] nbaj2k:
Thanks a ton for this information! I'll definitely look for that other thread and check to see if there are others that work (probably more expensive though)

I'm sure it's a stupid question, but how should the quality of using that cable compare to using an AUX cable? I'm going it would be about the same.

Again thanks to both of you for your help!

[Galaxy S III Accessories] canicula:
I am using this cable on my S3, and after installing a noise remove filter i can say that the audio quality is better then the AUX from the headphone jack.

I try'ed this cable on a friends S4 and it work exactly like on my S3. You have to check audio output in settings/accesory. Works with stock rom on both the S3 and S4.

Like someone mention it in a post above this is USB analog not USB digital.

You can get USB digital only with a OTG cable and a compatible DAC.
[Galaxy S III Accessories] nbaj2k:
This is great info, thanks! I'm deciding between either doing this, or buying a Himediy Sabre Tiny DAC which I guess supposed will work with the S4. Since I hope to load Cyanogen or another AOSP ROM on my S4 whenever Hashcode is able to finish the Safestrap to circumvent the bootloader, going with the iBolt cable may make the most sense (since Cyanogenmod has some issues I guess with DACs) .

Since I'm not an audiophile, with the noise filter on the cable I might not be able to tell the difference between this and that DAC.

Just wondered, for that noise filter, do you find the sound to be lot quieter? I had read some negative reviews on this iBolt cable, but that's great if the noise filter helps that much. Also, just wondered is the MicroUSB end of the cable made out of rubber or hard plastic? Since my S4 Neo Hybrid case has issues with anything more than a slim came (like oem) I'll probably need to cut it a bit.

Thanks again !

[Galaxy S III Accessories] canicula:
I installed the noise filter on the power circuit of my car (vw golf mk4) to remove the cirps an squeak noises coming from the ground. After that, the sound was much cleaner and deeper than before. I also use Neutron music player because it better it has a better quality than other players. Before that i was using Poweramp but Neutron is much much better. Also the cable i am using came from China after i found it on ebay. Tomorow i will post some real pictures with the cable so you can figure it out if it fits your case.
