Android CarPC audio Out - Android Q&A, Help & Troubleshooting

Hi,
I would really like to build a carpc using Android x86 and maybe an intel nuc or zbox.
I'm just hanging at some question:
I need 3 Channels "left / right / bass" is there a way to get android to send a 2.1 Signal on the Audio out ?
I would need a Hardware with 2 jack outputs 1 for stereo and the second one for bassline.
Is there a way to map the outputs to the channels ?
Is it hard to get the other devices like gps and w-lan work ?
Thanks in Advance
Simon

Android as a2dp bluebooth receiver?

I know its possible to send audio from an Android phone via bluetooth to a PC using the a2dp profile. But I want to do it the other way. Connect the phone to my amplifier and send audio via bluetooth a2dp from my laptop.
I've searched but not found. Anyone know it it's possible?
I think the standard BlueZ stack can't do this. I think the Broadcom BTLA stack might be able to do this ... IF you have the Broadcom Bluetooth chip inside.
Hi Pananza,
did you have success to use an android device as a2dp receiver? I'm looking for a solution but I didn't find anything useful.
The only solution that I have found is to use the NDK to access the BlueZ stack, but I'm not sure if this is the right way.
Thanks

Using phone as A2DP receiver
Hello
I would like to do this too, have a Sony MW600, and it works perfect with laptop or my HTC Desire, but it can not be charged and used at the same time..
Will it be possible to do this on an Android that is not rooted?
Did anything ever come of this? I'm looking for an app that would allow android to receive bluetooth a2dp or whatever the basic format is (mono ok), and output audio on the headphone jack of the phone. Bass ackwards to what all other apps i've found are doing. I've always been a "special needs" user

any update on this?
Wanting to use Android OS in the dash of my vehicle hooked to the audio system and use bluetooth a2dp to connect to mobile phones to play media through the system.
I'm looking for a similar setup. Has anyone found a way to turn android into an a2dp receiver?

You can transform your device into a wifi music receiver with the app called soundwire, you must install a server on your pc to stream audio from your pc to your android device. I didn't find anything with bluetooth.

Same here. More and more people are going to have "last years" android phone lying around doing nothing and this would be an awesome way to re-purpose it.
Whether it uses BT, Wifi, I don't care as long as I can stream audio from one android phone to another. What I don't want is to deal with DLNA or manufacturer built in BS. Just need google to turn on the A2DP sink profile and be done with it. The hardware is all there, just need the software to take advantage.
The next best thing is one of those BT reciever dongles/boxes. They run about $20 I think. So PSA to android developers - if you can enable this in a paid app I'm ready to buy it and I'll bet a lot of others are as well.

Did that tutorial works for you?
I've tried, but it doesn't work. My Panasonic TV doesn't see my phone, so I cannot play the TV audio thru my phone.
Any ideas?
Thanks!
I was also looking for an app like this.
For my old phones, my android sticks, ... no progress I assume ?
Waiting the same here! My idea is to buy a bluetooth transmitter, connect it to my TV and receive the audio on my phone.
I can't think that is not possible! :crying::crying:
Truck Tablet Install
Hey Everyone,
Been very curious about this as well as I'm going to do a nexus 7 install in my truck and want to be able to bluetooth additional music aside from what is on the tablet through the tablet to my speakers. Kind of a necessity due to the lack of a 3.5mm aux into the stereo. Hopefully we can figure this out!

?
I'm also looking to do this.
I'd like to be able to connect a Bluetooth transmitter to the output of a mixing desk, and then just use my phone to receive the audio (which I'd then want to save with something like tapeatalk).
This could provide a very quick method of recording gigs or DJ sets in stereo, and would be better quality than simply using the built in mic of your phone.
a2dp sink.
Bluetooth File transfer app can stream music from another phone. And this is where tha first phone works as a a2dp sink am I right? Can't we use that to built an app to follow it but using pc/laptop as the source?
Seems, that no one is interested. What a pitty, it could be really HOT stuff. For example, cheap android phone pluged instantly to a charger and to Car Audio via AUX, and You have got Bluetooth automatic pairing system for calling and music, navi etc.
Unfortunately I couldn't find solution for this, neither the app. It is strange. Some people says, that Android can not be a sink (reciever) in a2dp profile. So how does microphones from earphones are streaming audio to a phone, hmm?
Maybe someone will do it
I have a LG G3 and it does it flawlessly. It have a function called "Turn Audio Channel mode" on bluetooth settings.
I'm wondering how to do the same thing on any other andoird phones.

[Q] Routing GSM module's sound

Dear all,
I'm working on custom hardware built on Amlogic AML8726-MX SoC. I have the board working with Android 4.2.1 compiled with telephony support. We use standalone GSM module from Telit and I successfully implemented RIL and I'm able to make or receive calls. Unfortunately I'm stucked with routing the audio. The module has digital i2s interface and I connected it through I2S<->USB Audio converter to the SoC.
So now I have two Alsa devices - one is dedicated to analog interfaces (speaker, headphones, microphone) and is working in android applications. The second one represents USB audio and I'm able to use that on kernel level with command line interface. Now I need to to connect these two together to be able to play the voice call using analog interface.
Is there please anyone who can point me into right direction? I'm experienced in kernel development, but going into higher levels is new for me. Can such thing be done just by altering audio_policy.conf and related files or the issue is much more complicated that I expected?
best regards
Jan

[Q] Road Veles Android car stereo add bluetooth support?

Hello all,
I'm after a little bit of guidance on how I might add Bluetooth support to an Android powered Car stereo. It is a "Road Veles" single DIN WinCE and Android device with a 7" flip out screen. The reason I bought this stereo is to run an app by the name of MSDroid. This app was to connect to my vehicle's engine management system via Bluetooth.
Can't post links yet, easy search on Google for Road Veles, look for hit on Chinavasion
The specs say it has Bluetooth, but having tested the device out on the work bench what the specs don't say is that the bluetooth is only accessible for handsfree from WinCE, there is no bluetooth for Android. WiFi via USB dongle works great. I have purchased but not yet received a combined WiFi and Bluetooth dongle. I would very much like to have this combined dongle work with the device. The Bluetooth control is not visible under WiFi control inside settings like it is in my Android phone.
Can anybody point me in the direction of where to start with this? Can I root the device and mod to add bluetooth? Is there another ROM I could run? I have done a lot of searching but can't see much at all out in internet land on this stereo!
Any help greatly appreciated! Thanks in advance,
Arran
Hi, I'm not sure how these sort of things usually work, what sort of dollar value would usually be associated with making a some tweaks to an Android build? ...
Hi again, still looking into this. Any ideas how to tweak the Android 4.0.4 OS to make bluetooth appear inside the settings menu?

Send my HTC ONE M 8 by Tapatalk
I have a problem with the audio also. Installed remix is on windows 10, works great but only audio is send through USB speakers. I really want to redirect it to the usual internal soundcard but I can't seem to get that fixed. Does anybody know a workaround for it? Thanks.
Ditto same problem in Intel Nuc :0) bluetooth works fine but would like to use my surround sound.
Any input greatly appreciated
/S
Any updates on how to enable sound on Intel Nuc? I have the same prob. No sound through HDMi.

Any workaround to connect to H/K Amp Airplay?

I'm just wondering if there is a workaround to connect Mate 20 Pro to Harman Kardon's "Airplay" system ?
I have the AVR 370, and I could connect iPhone to its Airplay wirelessly to play music.
I know Airplay is made for iOS ... still is there a way to use this amp for Android devices?
I would hate to replace the amp just for this!
But, if this is absolutely impossible ... which amps would you guys suggest with android compatibility?
It doesn't have to be an AVR, but a HDMI-ARC / Audio Return Channel must be there.
Thanks
