USB audio out - Galaxy S 4 Q&A, Help & Troubleshooting

Hi all, I recently upgraded to 4.4 ( tried several roms, on omni now) however I can't find an audio out option anymore... I use my ibolt dock in the car a lot so really missing it!
Does anyone know how I can get this back without going back to 4.3?

1.6 stopped headphones

after the 1.6 update i can no longer use my headphones. i was able to use them with toggle headset widget before. anyone know how i can fix this?
anyone have a solution, i cant listen to music
Me too
I'm having this exact problem. It was odd; when i first installed 1.6 the headphones flicked on and off for all of 5 minutes and then stopped working fully. I have the standard usb to 3.5 converter that came with the phone, and it seems to work in another device.
I tried a couple of fixes that had been suggested to people having a similar problem when they had upgraded to cupcake but neither of these worked.
Halp would be appreciated
What radio version you guys have?
First thing i read on your reply was about cutting throuats and spreading cheese which totally threw me...
Anyway, am using CyanogenMod 4.1.999, and if i'm right in thinking radio and baseband are the same thing..... 62.50s.20.17H_2.22.19.261
I just updated to the latest mod 4.1.9999 and still it won't recognise the headset. It is the original one that came with my G1.
Have searched fairly extensively and can't find anything.
Any pointers or suggestions would be very useful.
theres an app called sound route switcher, its updated and i heard it works, but i dont have a credit card, wish someone would update headset toggle widget

LiquidAUX Bluetooth Car Kit & 2.1 ROMs

This isn't supposed to be some sort of complaint or anything, but was just wondering if anyone had any suggestions/ideas why my K33428US LiquidAUX Bluetooth Car Kit stopped working with ANY 2.1 ROM (FRESH & Damage)
it worked great with 1.5 but honestly I am not rolling back now, will just have to use the headphone jack for now.
At first I thought it was an issue with AD2P in general but then i started to see posts where people had success with it, so now i am disappointed.

Problems with Audio on Car Dock

Okay Ive been looking for about an hour now and have given up on the search for this. But I'm trying to get my cardock to play music through the 3.5mm jack on the back of the dock when its plugged in. I've found a bunch of useful posts that fix it in Froyo but I can find any fix to work on Gingerbread. Specifically I'm running latest CM7 and using the regular CM kernel. If there is another kernel I can download to fix the problem or anything please let me know.
Thanks!
are you in the right forum? (Samsung Vibrant).
I don't know of a car dock, and there's no port for it. The USB port is on the top.
I have the desktop dock and I couldn't get the sound to route through the external speakers either. There is a setting in CM7 but it doesn't seem to work. I also had an app that would re-route sound for the car and desktop dock that works great on 2.2 and 2.2.1 but it would not run in CM7.
To my knowledge, and this is running with Froyo, the only way to get the audio to come out of the car dock 3.5 mm jack is to use the Samsung Car Dock application. I May be wrong, but this is what I have discovered so far, which sucks as I really prefer the Google Car Home app.

My Continued Bluetooth Nightmare

OK,
So I'm trying to get some help regarding this issue. I will continue to try different ROM's and what not to see if it can be resolved. I'm simply at a loss to where the issue lies though, however as of today, every custom ROM has been giving me trouble. My plan for today is to flash a stock ROM via Odin and then if that works go for Imperium, however I'm hoping with your help I may be able to solve it on something like CM12 or what not because I prefer the flexibility of a proper custom ROM.
OK, so the issue I have:
I have a car head unit which has bluetooth built-in. Music plays fine through Bluetooth, no jitters or issues. However, when I try and call someone and I'm listening to the radio or something non-Bluetooth, the phone does not send the signal (?) to the head unit to switch to Bluetooth. This means the call will be made via the dialer app and while the audio IS being routed through the bluetooth channel, the head unit does not know about it because it hasn't received the signal to switch to Bluetooth. I can switch it manually to Bluetooth and make and receive calls, but this isn't convenient at all and probably quite dangerous when I'm driving a car. The same applies when receiving a call.
Here's the thing, if I go into Bluetooth, select CAR KIT and go configuration, if I disable Media Audio, then it works fine! The phone correctly sends the signal to switch to Bluetooth and the head unit does so. The call goes through and it all works fine. This is repeatable.
Therefore, the issue I'm having lies in the fact both Media and Phone Audio are enabled at the same time. Has anyone else had this issue and does anyone have a suggestion to fix it?
Before someone suggests "just disable media audio". My answer is no, this isn't convenient at all. I use Bluetooth media quite a lot, and simply disabling and re-enabling it everytime simply isn't an option.
So far, I've had this issue on:
CM12.1 Optimized
CM12.1 Nightly
Mokee ROM
DirtyUnicorns
CM12 Nightly
I'm yet to try a stock Lollipop ROM. I know for a fact however, that stock KitKat DOES work.
I really could do with some help here, so any suggestions would be awesome.
all the roms you have tried are aosp....aosp is not designed for the s4 as its not an officially supported device (its not a nexus) so things like bluetooth and the camera will always be broken as the required stuff needed is proprietary to samsung
go back to stock and your problem will be solved

The Bluetooth itself is fine. Audio quality is fine. Call quality is fine. It just seems like a tiny little thing that's causing all these issues for me, because if it could trigger my car head unit to switch, I wouldn't even dream of stock. Also the camera seems fine to be fair?
I'm not keen on going back to stock.... at all, so I'm thinking Imperium. It's a shame though because apart from this BT issue, CM12 is fantastic on this device. Takes a 2 year old phone and makes it feel like a brand new phone.
I really hope someone can fix that Bluetooth bug in CM12.1. I may even look myself, it must be something pretty small from a coding perspective because as I said, the functionality is clearly there as evidenced by the fact it works with Media audio turned off.
Regardless, thanks anyway
Changing the modem did not solve my problem.
When did you try the Optimized and the nightlies? There have been a lot of fixes lately regarding bluetooth.

Bluetooth issue i9505

Dear forum,
really looking for some help with the bluetooth connection and/or some pointers into the right direction.
Before anyone asks, yes I have searched the forum(s) and googled days in a row, tried several builds and found a lot of bluetooth questions/issues but not this specific issue nor a solution.
Have a S4 i9505 which has a perfect bluetooth connection with my Renault Carminat system using the stock rom. As I had other issues with the stock rom, I rooted and upgraded the phone to Optimized LineageOS 14.1 (7.1.2). When pairing the phone to the car, it all works fine (it doesn't disconnect - which is a commonly reported issue). media streaming works fine, the car audio system also responds to the phone (and vice versa), contacts are imported etc. The big issue is however that there is no sound (nor receiving nor sending) when a call is received and/or intitiated.
In my quest to resolve this issue I let the dealer upgrade the firmware of the car audio system, tried with at least two different (but similar) S4 i9505 phones on custom roms, tried several other custom builds (from CM12 to CM14), tried an older but also the latest modem/BL for my region (XXSPQA1), tried some nightly builds but in all cases the exact same issue remains. Only when I go back to the stock rom, I have again a perfect bluetooth connection. A S5 (with stock Android 6) can connect to my system without issues as well.
So my thoughts are that the issue lies within custom roms as even a custom rom based on the same Android version as stock rom doesn't work properly.
Any thoughts what I can do more? Is it possible to copy the BT files from the stock rom and copy it to the custom rom? Any ideas? If it can help to post certain logs I will absolutely do so. Phone is on stock rom again now.
Thank you for your support!
I have exactly the same issue on my I9505, every time i connect to bluetooth (previous car, new car bluetooth speaker calling seems to work , but ther is no sound (only the end of call beep. and also, after disabling bluetooth, the sound is still not working ... i have to reboot my mobile to be able to call again. i hope this issue can be resolved
( when connecting to a bluetooth device for playing media blutooth works )
Same here. I hear a distortion sound when a call is made though. Worked fine with 5.X and broken in 8.0 and 8.1. I tried various modems as well. I even changed codecs in the developer options and didn't find one that worked. i9505
