Android USB audio output NOT working in my car - Android Q&A, Help & Troubleshooting

Hi People!
Here's the story.
I have a Fiat 500 with a 2015 Fiat original USB radio. It does not support bluetooth audio streaming. Only AUX through 3.5mm jack or USB AUX. Or well, I should buy one of those bluetooth aux dongles.
If I plug an iPhone via USB, I can listen to Spotify though my car hifi with no hassle, using a normal micro USB (+thunderbolt adapter) to USB cable.
I have tried to do the same with 3 android phones:
- Samsung Galaxy S6 NOUGAT stock 7.0 rooted
- Samsung Galaxy S7 OREO stock 8.0 rooted
-Samsung Galaxy S3 NEO Nougat AOSP 7.1.2 rooted
No chances to tell the phone to send the audio through the mini USB port. I am using the same cable that I used for the iPhone, without the thunderbolt adapter, obviously.
My phones are all rooted and I have tried to modify the usb functionality inside the Android developer options. I have also tried an app (Audio Router 2.2 updated on 2018-01-22) that sould force the usb audio routing, but with no luck.
Is there anything I am missing? I have tried android auto but it did not let me add Spotify to the dashboard.

All Car Stereos won't recoginize S4 over USB!!!

I just got a new Chevy 2014 Silverado Truck that has USB and Bluetooth connectivity for Music/Podcasts/Pandora etc....
My wife's iphone 5c works through the USB for music on the phone and pandora/spotify. She can plug in the phone to the usb and control all audio right from the truck Stereo.
But my Samsung S4 won't work at all. Just through Bluetooth and that is kind of flaky too. I have tried to change the settings on the USB connection in the phone when I connect it. I change it MTP and still doesn't work.
I don't think its the truck because my wife's phone works and USB thumb drives work with music also.
Update:
I even just bought a new head unit for my Car. 2014 Pioneer x8600BH that claims it works directly with Android through USB with MTP....
Wrong! It doesn't work with my freaking S4! Why is it so hard for Samsung to work through USB with other devices?!
Bump....
Anyone have any luck with Chevy Silverado or even what Aftermarket radio's to buy?

That's because it doesn't push sound through USB...just Bluetooth and headphones Jack... There probably is no remedy for this but maybe there is...I just use aux cable from headphones jack to jack on my stereo

I am assuming that he is looking to use his s4 as a hdd that his head unit can read the data on when in MTP. I also was in a Chevy vehicle with stock cord and stock room and this was an issue that I never got solved.
Sorry I can't help more.

Is the phone it works with also a Verizon S4?
I think the problem is likely Verizon and not Samsung. Verizon put a ridiculous "installer mode" on their S4 that afaik isn't possible to disable and automatically activates first each time you plug your phone into something with USB. So the device you're plugging it into will see just a CDROM, and then 30s later it will change to MTP. If the device isn't able to handle that change it won't be able to work with a Verizon S4.
You can fix that by flashing a non-TW/non-VZW rom, but if you're not on MDK that's not an option...
There MAY be a way to disable the installer mode or enable UMS mode with a Safestrap rom, but I'm not sure on that.
What ROM are you on? I have an slightly older Kenwood deck that didn't work on stock 4.1.2 with USB but now that I'm on a non tw ROM it works fine. Its a touchscreen Bluetooth deck and my Bluetooth connection was OK. But not ideal the USB works much better.
I have a Canadian s4 sgh i337m that I flashed to look like a gt-19505 can't tell you which Roms worked for me but I'm on dandvhs Google rom now and it works for me. Hopefully you find some luck with a different rom

I have a 2013 Malibu with the same radio software and I'm pretty sure the USB only works with iOS. The music app on the stereo is called "iPod" after all.
I have an American Verizon S4 with a 64gb Samsung SDcard... I am running HyperDrive 15 on MK2 safestrapped.
My new Radio in my car is a Pioneer DEH-x8600BH and I can't get the USB to work with it... It says MTP is supported but I think it doesn't support the change in the settings after being plugged in.

[Q] Galaxy Alpha and Car Stereos?

Hey all I'm just wondering if anyone knows of any aftermarket car stereos that will work with the galaxy alpha running 4.4.4 via USB connection I know the newer pioneer stereos connect via USB to android devices with MTP I'm not a fan of having to use the Aux port of my stereo or bt audio
Sadly that is why I'm having to getting rid of this phone as it doesn't have MHL and won't work with my Kenwood Excelon DDX8901HD radio. I would check out Crutchfield, they are helpful.

USB-C Audio adapters

Hey all,
I'm looking to buy an tab S3 but I want to use it in a very specific use case where I need to use a USB-C to audio adapter (yes, I know it has a 3.5mm jack plug).
We have the tablet at work but because it's for a client I can't just tinker around with it.
I tried the USB-C adapter that came with the Google pixel 2 XL but that didn't work. The Tab S3 didn't play the sound over the speakers and paused when I plugged out the adapter as if it recognized it but I could hear anything. Does anyone have experience of a adapter that does work?
Also, does it work with the cheap passive adapters without a DAC? (USB-C audio can be analogue if the device supports it, other only do digital and require a DAC)

Hidizs Sonata HD USB-C to Jack 3.5mm DAC not working on S20 with USB-C connection

Hi all,
I bought the Hidizs Sonata HD USB-C to Jack 3.5mm headphone adapter with integrated DAC.
When I connect the dongle to my Galaxy S20 (Exynos CPU) USB-C port, the device is not detected and audio output goes to phone speakers.
The strange thing is that if I connect in this mode: SONATA HD USB-C PORT to USB-C to USB-A adapter to USB-A to USB-C OTG adapter, the device is recognized by phone and works good.
It seems that the phone detects the device only if OTG (and then usb host mode) forced by hardware adapter (SAMSUNG OTG ADAPTER).
Do you think it is a problem with the S20?
Thank you!
I have the same adapter, and works for me without problems. My phone is S20 ultra 5g european version. The installed Hidizs firmware version is audio priority, software for playing music is poweramp.

thank you serafko! I just tried on my friend phone (Samsung Galaxy S8) and the adapter works (some disconnections but works).
I have the audio priority firmware also.
I think there are some settings on my s20 that blocks the activation of the usb host mode

Activate Developer options>default USB configuration and see if mucking with the USB settings perk it up.
The S20 may not be supported by it,same issues on the 10+ with some dongles.
It must have a built in DAC chipset if the S20 doesn't provide one. I'm not sure if it does or doesn't.*
If others say it works on the S20, it should otherwise get one that's known to be compatible.
*edited, my bad

I tried to change default usb configuration in developer mode but not solved. Tried all options.
The Sonata HD has an integrate Hi-Res DAC.
In addition, after about 70 connect/disconnect attempts, my s20 detects the DAC, works for 1-2 min and then stop working. After that, the phone has not detected the DAC anymore.
The strange thing is that if I connect the DAC via an OTG adapter, all works good without any issues.
I tried "USB Host Diagnostics" App, but no device is detected.
Furthermore I enabled USB debug to view the logcat via ADB. When I connect the device on USB-C port I can see a "BATTERY CHANGED" event on the USBProvider module, but android not detects any device connected on USB-C port.
If I connect the same DAC on a s10 (with same android and EMUI version of my S20) or on a s8, device is detected and works, so I think that isn't a defective device. It seems that Android not activate USB OTG mode when device is connected on the USB-C port.
@serafko has my same phone and the same device (with the same firmware version) and he has no problems. This makes me think that more than a compatibility problem with the S20 is some Android setting that causes the problem.

Settings>sound and vibrations>advanced sound settings>sound quality and effects
Is the UHQ upscaler enabled when you connect the device?
Could power management be killing the apk(s) needed?
Power management (other than the power setting, Optimize is best) causes nothing but trouble.
Developer options>stand by apps, all app buckets should show as active, if not power management is active and probably running amuck, as usual.

The UHQ upscaler is disabled (greyed out) with both the connected and unconnected device.
In the Stand by apps I have some apps greyed out with different states (RARE, FREQUENT ,EXEMPTED, etc).
Do you think this could be the problem?
In this case how can I solve?
I have currently enabled "Optimize" in power management.
Thank you so much for your help!
EDIT: I just disabled the "Risparmio energia applicazione" (I think Energy saving app in english) and now all the apps in the Developer options -> stand by apps are in the "ACTIVE" state....same issue! Device not detected and UHQ upscaler greyed out.
EDIT2: Also tried to enable the developer option "Disable automatic audio routing": same issue!
I think this is doable but you're going to have to play with it. Contact the manufacturer if all else fails.

I contacted technical support but they replied after 4 days with a classic standard email.
Also I tried to flash all 3 firmware (now the device is with "D - Pure Music" firmware, the same as the other user.
Finally I did all the tests both with the app they recommend (HybyMusic) and with USB Audio Player PRO, setting the BitPerfect option and exclusive access to the USB port. This way the app bypasses the android usb stack and uses an optimized driver.
I also tried to clear the data and cache of the system application "Usb settings", but despite all these attempts I could not solve it in any way.
At this point, considering that the manufacturer's assistance is practically non-existent, I believe that I will return the product directly through Amazon.
I am very sorry because the DAC quality of this device is amazing and I do not know if I should order another one as I honestly have not yet understood if it is a defective product or compatibility problem.
Anyway thanks again for the help!
As soon as I plug in the Samsung dongle it recognize it and the UHQ upscaler options are available.
Poweramp shows the Samsung 3.5mm adapter with 24bit 48khz sampling rate being outputted.
For whatever reason the phone isn't recognizing the device.
I don't know what the communication protocol is for the linkup. Sorry.

I have the Samsung dongle too and works like a charm with all apps (Spotify, PowerAmp, etc).
I'm considering to buy an bluetooth DAC like the Fiio BTR5. It works both as Bluetooth or USB-C DAC, so I would be sure not to have compatibility problems.
Thanks again for the help!

You mean you want to transmit the audio in the bt realm with the BTR5?
Even using the LDAC or AptX-HD codec the resolution and quality will be inferior to the Samsung dongle DAC to 3.5mm audio output.
BT lacks the bandwidth to support 24 bit 96khz resolution.
If the device you're coupling by bt doesn't support AptX-HD it won't do anything the phone bt chipset can't do*.
I believe that phone support the Sony LDAC bt codec, unfortunately only Sony headphones use it.
If you want to use bt headphones with the best easily available HQ audio I go with Sony.

This is a more reasonably priced LDAC headphone set than the top shelf Sony WH-1000XM4. For almost $200 less it doesn't sound as good but pretty close. Compare all the features first if you decide to go this way.

Lol I have a 10 yo pair of Koss Porta Pros, the still work and sound damn good using the Samsung dongle. Not bad for the $29 I paid for them back then. There still around and a classic for good reasons.

I am sorry, that i missinform you. My Sonata firmware is not "audio priority", but is "pure audio (D)". When i plugin DAC into USB port, Poweramp start automaticaly.

The Fiio BTR5 supports all Bt codecs, LDAC included. In Bt mode supports up to 96Khz 24bit but in USB mode supports up to 384khz with DSD256 native. The dongle has 2x ES9218P DAC by Sabre.
The Samsung dongle.
The samsung dongle actually has very high quality, in fact I was surprised, but it has a hard time driving my 150Ohm Shure headphones. No problem with my Bose QC20 instead.

Sorry, my mistake. The firmware I loaded is "SONATA _HD-D_Pure".
Hi Guys.
Just tried the Sonata 2 on S10+ and I'll let a fried try on S20 soon.
This product looks like useless and malfunctioning.
Talking about S10, it integrates a great DAC, it's just heavily limited by software, I don't want to know why...
I rooted it and, modding the mixer_gains.xml, installing Viper4Android and using dynamic driver based headphones it's absolutely unbelievable.
Anyway, Google just improved SafetyNet, they'll soon close the door to any root solution, Magisk included, in a short time we'll have the most of apps refusing to run on rooted phones.
That's why I'm searching for a decent type-c DAC cable.
Coming to the Sonata 2, its volume is just acceptable, but bass frequencies are too weak.
Moreover, its connector is unstable, there's frequent disconnections
Also the game of the 3 firmwares is absurd.
I flashed the sound priority firmware, honestly this firmware increases sound quality a little bit, but it shockingly fails to manage the microphone: on outgoing and incoming calls microphone doesn't work at all.
Finally, reverting to call priority firmware, the microphone still doesn't work.
In my opinion this product looks like the usual chinese bull****, do you confirm?
I'm actually looking to something better, but it prefer it in the "cable" form, using it for work and sport a big device wouldn't be so comfortable...
Regards
Ok the provided cable is not bidirectional the one with the logo should go into the phone.

Question Mi mix 4 USB audio

Hello I would like to see if anyone here could kindly help me. Basically I have a mi mix 4 on miui 13 eu rom I have a usb c cable that connects to 2 pin iems the cable has a dac built into the usb c housing the cable works fine on my old phone but with the mi mix 4 occasionally there is a subtle static sound. My old phone doesnt support passive usb audio so a digital signal gets sent to the dac where it turns into analogue since it works on that phone the cable itself isnt the problem however I know xiaomi phones support passive analogue out the usb to 3.5 mm adapter it comes with doesnt have a dac in it and works fine with earbuds with a 3.5mm jack so I was wondering what I can do to fix this issue could a software update to miui 14 eu rom help or should I try pixel experience? Is there someway to make the phone not detect the external dac and bypass it because id be fine with using the internal dac basically by forcing audio adapter accessory mode. I wish I could find a cable that as usb c to two pin that didnt have a built in dac but it seems like it is such a niche thing. All this to avoid having to use a adapter lol
