S100 car avn system no sound - Android Head-Units

Hi. I am not sure if this is the correct platform to ask this, but I have a S100 car avn system that does not play any music via USB , it counts down the songs but no sound at all. Any ideas? I tried all sorts of formats and different USB sticks and it looks on the screen like it is playing but no audio. If I write the same songs to cd of DVD it is fine.

I have exactly the same problem...Did anyone find a solution to recover sound when it plays via USB or SD card?

Tomtom Bluetooth audio

you can't (AFAIK) choose which apps audio goes over Bluetooth, it's a system wide function.

[Q] shoutcast radio stream to USB car stereo

hey guys,
i was wondering if there is a way to listen to shoutcast radio via 3G to usb using my i5800. i have alpine cda-117 with imprint installed in my car. it has a usb connection. i want to use alpines usb to charge my i5800 and at the same time to hear sound on my car speakers using the same usb connection. is it possible?
the closest thing i did was i opened opera, pasted a link to a m3u playlist and opera asked me if i would like to save it as a mp3 file on my sd card. in other words it was saving the stream to a mp3 file but my car stereo couldn't see the sd card because it was already in use by opera. any solution ppl?
i wan't to do this because:
1. phones DAC (digital audio codec) wouln't be used. this means the sound quality would be way much better*.
2. less cables.
*the sound from my phone would be sent directly to the imprint sound processor in digital format and then decoded to analog.
thanks in advance.
Sorry but i think there is no way to do so atm... you however could do it using Bluetooth if your car stereo supports this.
my car stereo doesn't have bluetooth that is why i was asking about the usb option. thanks anyway
what app should i use to be able to play shoutcast streams via bluetooth?

Streaming Audio via USB

Hi Guys,
Tell me, is it possible to play streaming audio (Spotify/Play Music/Apple Music) via the USB cable to the car stereo? Reason I'd like this over AUX is that I get to skip using the steering wheel. Worked fine with my old iPhone but can't seem to get it to work with the S8. It happily plays any music stored on the phone, but streaming audio doesn't work at all.
Tried setting the USB mode to 'audio source' in the developer options but this way my car (Ford with SYNC) just says 'USB device not supported'.
Any way around this?

Digital Audio Out via USB

The amp in my car (BMW E39) has a S/PDIF coaxial input that will only work at a sampling rate of 44.1khz. At the moment, I have the RCA analog line-level outputs of my head unit (Dasaita Max6, Android 9) running directly into an ADC that I have mounted on the back of the head unit, and from there I just run a single coax cable to the back of the car that then plugs into the amp. This sounds great to my uneducated ears, however it bugs my OCD-ness that the head unit is converting from digital to analog, and then I am converting this straight back to digital again. It would be better if I could just run a digital signal al the way through.
So, as an experiement, I bought a cheap USB to S/PDIF sound card off ebay (PCM2704), which I hoped that I would be able to plug into one of the USB outputs on the head unit and instantly get digital audio. Only it didn't work. I tried a heap of things and I could not get the head unit to output audio via USB. I did a bit of sniffing around the file system, and found all of the audio-policy configuration files (all are XML) in the /vendor/etc directory. There is a USB Audio policy file there, however the main audio policy file makes no reference to it. The main file recognises a heap of audio outputs (bluetooth, headphones, speakers etc), but neglects USB.
This is as far as I have gotten so far. There is very little info available on this that I could find. I few people managed to get this sorted on Android 6, but all of the audio policy files changed between Android 6 and 9. My next step is to see if I can add USB to the main audio policy file and see if that works, but before I do that, I thought I would post here and see if anyone else had tried this before.
I'm aware of things like USB Audio Player Pro, which uses it's own proprietry drivers to send audio out via USB, but this is not really suitable to me as it won't work with other audio sources, like Youtube, youtube music etc.
So has anyone had any experience with this? Has anyone gone down this path before? Any suggestions or ideas would be much appreciated
Have you get this resolved? i have the same question about it.
