[Q] Android L USB Audio & Mic Support - General Questions and Answers

With Android L featuring native USB Audio out is it safe to assume that all USB DACs will be compatible with all devices? It almost seems too good to be true
Also with upcoming USB Audio out can you have a hardware 3.5mm microphone-only (without speaker) plugged into the AUX/headphone port, and still output sound through USB? The way it behaves now when you plug in a microphone it assumes it's a headphone/mic combo and outputs sound thru the AUX port. I'd like to take the mic for input but still output sound through USB.
Thanks in advance.

is anyone able to answer this?

[Q] USB Headphones

My headphone jack stopped working a while ago. Haven't been able to fix it but I do have a USB Headphone but it doesn't work when I plug it into my Transformer. Any fix or mod for that? I also have a bluetooth headphone but streaming seems to suffer whenever I use it. thanks!
Transformer's kernel does not support usb audio so IMO without deeper modifications you're not able to use it. I also have a bluetooth headphones and on A2DP profile it works great.
You could also replace the board with the headphone jack.

Splitting the 3.5mm jack with microphone and speaker output - possible?

Hi All,
I was wondering if the below scenario is possible with any android phone.
- Plug a 3.5mm splitter into the audio jack (two female ends)
- Plug a speaker system (headphones, whatever) into one split port
- Plug a microphone into the other split port
Would the phone play audio (music, etc) through the headphones normally? If someone were to call, would the voice on the other end play through the headphones and the microphone work for me to talk to them through?
Thanks!
EDIT: Since the response has been overwhelming I went and tried the method above. Works perfectly. Thanks to... me *self high five*.

Recording stereo audio via USB

I've got some stereo audio going into a USB audio interface which I want to record onto my phone.
I've plugged the USB adapter that came with my S7 edge into the mini firewire/charging port of the phone, and connected the audio interface USB cable to that. I've tried a couple of stereo sound recorders like recforge but when I record the audio going into the phone from the USB, it comes out mono only and I want it stereo.
Is the phone not equipped to record stereo from USB or can anyone recommend an app or driver?

Digital sound out of USB C

Greetings,
I would like to find out if/how I can get the digital sound out of the USB C port.
I want to use external DAC/amp to run in-ear headphones.
I went to the developers settings. The USB audio routing is enabled. I also switched USB default interface to MIDI.
The DAC/amp I am using is XtremePro, thumbdrive type USB/3.5mm device. The player is foobar2000 for android
Unfortunately, I get no audio out. Is the problem my DAC, needing drivers to install? Or is it the device itself? What can I do to get the digital audio out of the USB C?
Any suggestions are appreciated.
Thanks much
