I would like to purchase a new cd head unit for my car and use my Zune Pass on my WP7 to play all my music via USB.
Why USB and not 3.5mm aux cable?
I would like to be able to charge my WP7 device and control volume/play/pause/etc from the car CD head unit rather than my WP7 device
Right now, the only CD head units I know of that are capable of this with Zune devices is 2 head units from Kenwood:

Has anyone tried this or have another method to get this to work?
thanks
I'm not sure what you are trying to accomplish is doable, and it's unlikely that it will be. The Win7 phones, at this time, don't have a standard Zune connector, which has specific pinouts for different functions, such as, passing audio, charging, basically controlling functions, etc. (much like the pinout on the iPods/iPhone)
Since all of the phones, at this time, have just USB mini/micro connectors, there has to be a driver associated on the receiver/computer/other device that knows how to communicate with the phone, process what you're trying to accomplish, and basically have digital two-way communication.
The more likely way, is to have a bluetooth enabled head deck, that allows two-way control (I'm pretty sure these are out, not sure about the two way), and a separate car charger...
Anyone else have any input that might help?
I have a kenwood BT-900 car stero that suports the zune hd through the USB port
it works awsome
I now have the WP7 and my kenwood does not see the phone at all only thorugh bluetooth but still does not do music streaming like to should
I beleave the will be testing the new phone out but as you know they don't tell me very much, all I know is the 2 of the support reps ordered WP7s and thought it would work fine but in fact it does not
I'm sure they will have some fix soon I'm hoping

thank you for posting this, I was researching to buy that particular kenwood strictly for this reason. you just saved me a couple hundred dollars.
My car is a Peugeot, about 2 years ago i installed an Extension Box so I can use an USB-Stick to listen to my music. (It uses the external CD-Case Port on the Radio.)
The small box also enabled to connect I-Pod and I-Phone and was able to browse & play from them.
When I connect my WP7 it beeps all the time and can't even load the battery.
As I know, the box writes a playlist on any USB drive which is connected so I suppose WP7 simply doesn't allow this =(.
Hopefully this will be changed by some kind of driver.
I have a KDC-BT8041U in my truck. I connect to it via Bluetooth and use a usb charger when needed. I usually just hit the random play button (the two music notes in a circle on main screen) in Zune Music and then I can use the remote or on dash controls of my Kenwood to skip forward and backward through the songs. I can also pause and mute. The only down side is it does not show song title, artist, etc. on the screen of the stereo and I can't search for specific songs using the stereo. But it is still much better sound quality then AUX jack and you wont have to get caught with your phone in your hands while driving. (illegal where I live)
Another cool feature about this is the music fades out when you get an incoming text or call then resumes after your done. Be sure to go to settings, speech and enable speech recognition over the network, then at the bottom turn Read aloud incoming text messages to bluetooth so you can respond to your text messages using your voice. Work really good.
Guys, you are searching unreal things. It's not a Zune player, it a diffirent device at hardware and connectivity too.
Only one way to use our phone in car is a Bluetooth. It work good, as headset and throught A2DP for hearing music and control playback from car hi-fi.

Are there any Android head units that support optical audio out?
I've been researching the last few nights (hours!) for a WIRED way to get a toslink optical cable to a Audison Prima AP8.9 Amp/DSP.
Are there any electrical engineers out there who have thought about bypassing the onboard DAC to get digital output?
Or.... is my only option to provide <96kHz optical audio to get an AptX lossless Bluetooth receiver like the Neet AptX lossless bluetooth receiver. Can anyone share experience on how well the Android units perform constantly connected to a BT receiver for all car audio? Esp. if you have the new Pumpkins with the Parrot BT card, in case that improves things.
Thanks!
I'm looking for the same answer, i've installed the neet receiver, but unfortunate for me, the head unit does not connect. I don't think it can be used as transmitter.
I've found this, but I don't know if it works...

You all may be overthinking this. Turns out plenty of modern android devices can use standard USB audio hardware. You just need an OTG cable, and the kind of USB audio output device that doesn't need a specialized driver under Windows or Linux. I've hooked up many different USB audio dongles you my Galaxy S3 and S4. The S4 wouldn't charge while hooked through the particular OTG cable, but the S3 does. As a matter of fact, I've been using it as the media player in my car for years.
Admittedly, I've only used the optical out on some of my devices occasionally, but I imagine it would still work for most.
Update: Not all supposed "OTG" cables work. This is the one I bought in Jan 2014 that works for both audio and charging on my S3 with CyanogenMod 11: https://www.amazon.com/gp/product/B009YPYORM/
Today I received an Android 6.0 Head Unit from A-Sure for an Audi A3. I connected a Terratec Aureon Dual USB DAC. I got sound, but couldn't control the volume. Changing the android system volume had no effect.
I am considering spending a couple of bucks on the app "USB Audio Player PRO" and test it again. If this doesn't work, i will have to return the unit.
Greetings from Germany
So i had to return the Head Unit. I tried a different one by "Skandinav", with this one there was no sound at all from the USB DAC

Hi,
You need to connect to DAC with digital volume control like Helix DSP Pro

yes, you can connect to the DAC, thereby outputting digital audio from applications and transport flash drive.
this can be done not only with android devices, but also with conventional tape recorder, some installations you can look at my YouTube channel

Well, don't fall into this hole. (warning to new users)
I have the Prima dac/amp, and the sound is amazing, and it can be connected to an Android phone via OTG to Toslink adapter, or via Bluetooth adapter with Toslink out, but it has one very nasty issue: when the amp is starting, and there is no Toslink signal, it won't register the connection. So if you later connect your phone, you have to cycle through the input sources Digital->Aux->Master->Digital to again register your connection.
So unless you connect your phone or turn on your BT receiver _before_ you start the car up, you will need to fiddle with cycling the source (while also driving the car). (That is if you also have the optional control unit with a display.)
Why they designed the device this way is just beyond me.
I hope its all right to join an old discussion.
I have a similar problem, I want to connect an android head unit in my car to an external digital amplifier. The amplifier itself have SPDIF input (mosconi GALDEN Pico 12 channels https://mosconi-system.it/product/gladen-pico-812-dsp/) but I can't find an android head unit running Android 10 with SPDIF output for my car. I've found converting card USB->SPIDF (for example: https://www.amazon.com/Douk-Audio-C...1&keywords=usb+to+spdif&qid=1617899902&sr=8-3) but I still missing some points:
-In Android 10, how do I switch all audio outputs to the converting card? Is it a part of the Android or external application?
-What happen when playing multi channel media (such as 5.1)? does each channel transfer on each on?
-Is it possible to use the same method to BT? The Pico have an optional BT card.
Thanks in advance, Haim

Android usually automatically switches to USB audio when found, but many implementations do not. Sometimes there's a setting in the developer menu for prioritizing USB audio, but sometimes that doesn't do anything.
USB audio of any kind is not supported on my Sony X800D Android TV.

Multichannel USB sometimes works, and sometimes doesn't. Certainly it can work, such as on many Android TV implementations like NVIDIA shield.

Multichannel Bluetooth is not a standard, although some implementations like enhanced aptX can support it.
Have you also considered that SPDIF surround is always encoded, and thus is output at a fixed volume? Your head unit would not be able to control the volume; it would have to be done after decoding, like at the power amplifier stage.

Do you know of if it's possible to allow the headunits to play higher than 48khz resolution through the optical or coax outputs ?

The unit forces 24b 48khz audio, coaxial can output 192khz tracks and optical upto 96khz . Higher resolution audio output.
Neutron or UAPP will allow higher resolution, but you'll probably lose Navi directions as those programs bypass the android audio layer and mixer.
Basically you need a high resolution non- Android media player, with a navi input and mixer, that also has an spdif output.
The Alpine UTX-A09 looks like it can do that, assuming it isn't Android based /doesn't force 16/48 output from all sources when the mixer is enabled (in non "Alpine Direct" mode). Looks like the Alpine pxe-x09 has a mixer, so it should also be able to mix in navigation instructions.
Some of the Helix DSPs may mix or prioritize different inputs - the documentation isn't clear.
If you use spdif connection vs optical you run the risk of creating a ground loop unless the source is floating ie running on its battery power.
You can blow out all your high frequency drivers in a second if the ground loop creates feedback oscillations.
A common ground point may or may not prevent it. Using toslink to couple eliminates this potential issue.
For car hookups best practice to use heavy gauge wire for positive* feed, preferably coming directly from the battery for high wattage amps, source auxiliary equipment from the same end point. Do not daisy chain.
Same is true with home hifi, avoid using spdif cables to couple amps, preamps, receivers, cable boxes, etc. Amps, recievers are designed to be floating and not connected to ground. Do mix earth grounded and floating equipment unless connected by toslink only ie a tower PC with a 3 prong plug and a reciever (2 prong plug, floating).
*if you use a chassis grounding point, use only one and do not daisy chain!

Sorry for the delay.
DTS has had 96kHz/24 bit for many years, and they work through any SPDIF interface... as you wanted. They don't actually change the hardware interface speed, but rather encode the extra data into the sales 48kHz stream.
I've never bothered to encode anything with it, because I'm guessing it actually makes compression worse. You're squeezing much more data through the same early 90s compression algorithm, and DTS is already lossy enough. Factor-in that higher sample rates are not detectable in blind tests, and it just seems like a bad idea.
Hmm... Unless the 96kHz/24 bit extension algorithm is much more efficient at compression, considering it was introduced much later than the base DTS algorithms in 1991, and may have leveraged more recent technologies. In that case, it would definitely be the better choice. Unfortunately, I haven't read anything about this possibility.
Good reading on the 96kHz/24 bit topic:

Bumping an old, but good, thread. I have exactly the same amp (well, the 5.9), and an Android unit with a TOSlink port - but it seems to be turned off as I can’t see any light coming from the TOSlink cable. Any idea how to turn it on?
I have a FiiO as a backup but prefer not to do SPDIF because I need another device for the Audison to take SPDIF input …

Toslink can support 24 bit/192 khz.
Optical coupling is preferred as it carries no risk of creating ground loops; optical isolation.
A ground loop can smoke (literally) all your tweeters and maybe the power amp in a second.

I think you accidentally replied to the wrong post. My topic was about the quality of the DTS 96kHz/24 bit encode, which is completely independent of which of the two physical SPDIF interfaces is used.
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
Daniel
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 ?
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.
