Hi Guys
I have been searching and researching for hours but can't get this to work the way that I want, although I don't see any reason why it shouldn't work.
I recently purchased one of my dream cars, and promptly changed the headunit to a more modern unit, to allow me to have spotify, google maps, etc etc. I purchased the Eonon GA8150A for this purpose, and it sounds OK.
I was always planning to upgrade the sound, namely using a Helix DSP and amplifier, upgrading the speakers, etc etc.
Since the helix has an optical input, I figured I could maximise quality by running a digital signal to the unit - to this end I purchased a Behringer UCA202, as its a class compliant USB DAC which has optical out.
I connected via USB, and went into developer settings, and changed the "Select USB Configuration" to Audio. I plugged in some headphones for testing, and....nothing.
After some research, I downloaded the Onkyo player, and this worked! I was getting audio via my USB dac, through the headphones. But spotify, bluetooth, radio, nothing else worked.
Was wondering if what I am trying to achieve is possible?
The only other alternative it to sell the uni, and purchase an AVIN Avant 3 unit - this comes with high quality 4V pre outs but its a lot more expensive and i really dont want to do this. I could use the RCA outs on the Eonon to feed the processor, but as mentioned, these leads to many stages of A/D D/A conversion that will markedly reduce quality.
Thanks

Ok updates - it now works - the inbuilt audio player via USB, spotify, both work, however the radio doesn't send audio via the DAC, and nor does it send audio to the dac from my phone via bluetooth.
Not sure why this works now, maybe I had to turn off the car a while so the unit could properly reset?
The head unit volume control however doesn't work to adjust the volume of the audio coming from the dac.
Any way to get radio and bluetooth working via the dac?
Cheers

Need a little help, I bought a unit but it's locked the Bluetooth to the phone and music streaming so I can't pair it to my OBD bluetooth dongle.
Other issue are the crap built in eq for sound control for the Audi bose system. Ran poweramp to get better music control and the eq in that sorted my music quality issue but it plays music at a low volume so when you switch to radio all he'll goes on due to the massive difference in volume levels.
so any help or suggestions would be great
I believe that PowerAmp has its own volume and balance controls that are independent from the unit's "generic" controls. What I recomend you do is set the unit's EQ to flat and use the PowerAmp to set the EQ the way you want. For the volume it would be the other way around; leave PowereAmp at max volume and use the system's volume to control it.
As for the bluetooth issue, how do you know it's "locked" for phone and music? It may say that on when you pait your phone, but that's only because that's what your phone supports but it doesn't mean you can't pair an OBDII device. In fact, I have that same hting on my phone but I'm still able to pair with my OBDII at the same time.
Are you using a custom ROM or are you still stock? I believe some people have had problems with some OBDII devices which are corrected with an Xposed module (I never had any problems so I don't have much more info).

I am curious what unit you purchased. I purchased an Audiosources unit for my A3 and after the initial test fit, I have no sound. I unhooked the unit and ran some wiring and now no sound from the radio, stored music, streaming, Bluetooth or even video. Everything powers up and seems to work though. I have not tried to pair a second device yet so I cannot help with that issue. When the sound did work, I did have the low rear volume issue that you appear to of had as well. Thanks.
When I hooked mine up as I have full Bose there was zero sound, I had to use a hi/lo converter which did the trick. The low sound I nailed down to the crap built in eq as I downloaded a great app that overrides it for everything bar the radio for some reason (app viper4android). My unit is going back due to a faulty volume knob, I will be ordering a different unit from some other supplier.
Thanks for the info. I have Bose as well. Can I ask what year and model your Audi is and the brand of the unit you returned and the new one you are considering?
Hi All,
I need some help getting my Sabre 9018 USB DAC to work with the Joying Headunit.
I have recently purchased a Joying 7" 5.1.1 headunit. The sound quality of this unit is terrible, and after hearing the 9018 DAC connected to my phone, I simply cannot go back to the Joying sound. I'm quite good at troubleshooting/mods for Android but not an expert at all.
I've managed to get sound out of the DAC when using HibyMusic player installed on the Joying without Volume control. Spotify/Poweramp/android music player simply do not work.
My Samsung s5 using Xstrolite rom played everything flawlessly through the DAC plug and play.
I've reviewed some threads regarding DAC support but nothing really helps with the 5.1.1 units. Hence why I need help from you guys,
Thanks in advance

the "workaround" for this is to get an external DSP, and then use the remote control of the DSP to control the volume.
Several of us here use the C-DSP 6x8 and it works well. It also includes SPDIF in, so you can go full digital all the way to the DSP. It is not a cheap solution, but if you can manage to find a good deal on a used one, it will allow you to control volume in the apps that have a dedicated USB driver. For non-critical listening, you can use your normal joying pre-outs, so you effectively get a fully functional system without having to heavily modify the HU system files.
Also there is a cheaper DSP available from minidisp called the 2x4, and you can connect an external potentiometer to control the volume. This would be the cheapest method of doing what I described above, and you still get the huge benefit of able to EQ your system with a real DSP.
Okay, thanks for the feedback. So even using neutron player, you still can't control the volume? I would try this, but Im away for work atm. Thanks again
Inside the app, yes, by attenuating the output. But you still get no sound outside of apps without a USB driver. That's why I like the dsp option. If sq is high priority it's the optimal choice regardless. Especially if you get one with digital in like the cdsp 6x8.
Do you hear FM radio and Bluetooth sound through USB ?
Hi all-
I'm using this usb type C to usb connector inside my audi for playing music off of the Nexus 6p through the car's Android Auto:
https://www.amazon.com/gp/product/B010VFFSL4/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
I specifically got this one since it meets USB-C spec as many cables out there that boast high transfer rates can ruin your equipment. I'm using the latest WETA ROM and have tried a myriad of combinations by turning off/on Viper mod, configuring its settings, also tuning the eq in my car, etc.
What's weird is that music over bluetooth sounds like much better quality than wired with this USB type C connection. I got an awesome aftermarket sub and amp installed in the car but it seems to bring out the deeper issue. It's when music (mainly rock) has all instrumentals blending that the sound becomes distorted and overloaded. Because our phones already have poor max volume output, I'm having to max out the volume in the car. Also with android auto, you can't use the volume rockers on the phone it seems...seems to override the sound volume.
Anyone have any idea? In this car I can't seem to play music with aux cable (maybe an iPhone would work) and USB stick doesn't mount songs. Don't know if it's the cable I bought, the ROM (has the A.R.I.S.E. mod built in), or the DAC in the AUDI?
Thanks
Hi guys, I am looking to put an android head unit into my BMW X1 (e84) and would like some thoughts/advice on the audio side of things.
TLDR; The unit requires the use of the aux port, which is low powered and too quiet - what are my alternatives?
Best I can tell all the android units for the e84 are essentially an extra side unit, as the original OEM HU stays in the car, take the following for example: AVIN BAVE84-1025 (I can't post the link as I don't have enough posts).
My only problem is the audio from the android needs to be looped through the cars aux port, which just seems wrong, as the aux port is low powered I'll never be able to get loud good quality audio through to the car speakers?
As it is at the moment, when I plug my android phone into my aux port, I turn the cars volume to maximum (including the extra aux volume) and it's still incredibly quiet. Is this because it's low powered aux, or is it my phone causing the quietness? (My phone is also turned up to max volume)
I'm worried that if I purchase one of these android units and utilise the aux port for the audio, I'll have the same volume/quality problem that I have when using my phone.
I used to have a 1 series (e87), where the android unit just hooked straight into the cars audio system, no need for utilising aux.
I have read that some people have left the aux unplugged in an F48 and the audio still worked (I'll see if I can find the thread for that) but obviously that's a newer model, so I'm not sure what's different.
I've also read a little about using a USB DAC, but I don't fully understand the process. Am I right in thinking the android device would need to be told to output audio to the USB, and the USB would then be hooked into the cars RCA audio?
At that point it's just another tablet, but with worse specs
See if connecting via bluetooth instead won't help. And try another device, maybe your phone is just being weird.

I'm still running the OEM head unit at the moment (professional head unit) but it doesn't have music over Bluetooth.
I'll try another device to see if it'll go louder, but as far as I'm aware the aux port is generally quiet anyway because its low powered.
I have a small amp that I thought could probably help but I wouldnt want to put too much power through the aux port in case it blows.
I thought if I could get the android unit to use a USB DAC, I could then hook into the cars standard audio rather than a low powered aux. I'm just not sure whether it's possible to have these android units output to a USB instead. Does anyone have any experience with this?
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.
