I am interested in connecting my phone to an external DAC/AMP (Fiio e17/e9) via its micro USB port and is wondering if this is possible?
Does Andriod OS support AUX preamp audio signal out through it's micro USB port? If so, which adapter should I purchase?
Or I could maybe do it by using a combination of adapters MHT to HDMI first and then HDMI to SPDIF (PCM signal) ? Any suggestion on the adapters?
Cheers
BUMP!
anyone?
I want ti do the same. I have a note 2 and would like to know if there is a method to connect the a fiio e11 via a 3 5mm stereo jack with the pre amp output from the phone?
regards

So I've been trying I find a solution for this, but it's been proving difficult. I have seen that on the nook forums, with a quick kernel mod and a tweak that allows USB audio control (i.e turn on switch for USB audio output), the guys over there have working digital USB audio output to an outboard DAC. Could anyone find out how to do this with cm7/cm9? Cm9 preferably. I assume we have basic USB host capability, since keyboards, etc. work, so its something specific to USB audio. This is definitely one of the only issues I need resolved on my TP.

This is very possible with USB host and OTG Y-cable adapters. When my cables and my computer come in the mail I will try tinkering with it. It'd be nice to see Jack audio running on here. Once July rolls around and HP releases most of their driver and kernel sources, development in all areas will skyrocket for our Touchpads.

Does the upstream port require power even if the device I'm using has its own power? My E17 has its own battery, but for some reason it isn't even recognized through the USB OTG cable. I can't even get USB audio to work on the WebOS side, which supposedly has full USB audio support via pulse audio now...

Hmm, I'm not sure. If it has it's own power supply, maybe you can try to mount it with a standard male microUSB to female USB. I'm about to see if I can get my external HDD with it's own power supply to mount to my phone and tablet. Will report back with results.

Has there been anymore dev on this topic, including the current CM mods? This would make an interesting project for a carputer if the USB audio works.
Hello
All we know that sound quality from lg is very low but there is another way to get audio signal - from usb to DAC.
Is some kernel supporting this feature?
Currently no Kernel is supporting USB audio.

What about USB OTG in new ICS?
Is there a custom ROM or Kernel that allows this? I've tried everything and can't get it to work with the stock 8.0.0 ROM.

I had same problem with same DAC. The only thing I found working was connecting DAC to externally powered USB hub and then hub to 1+3T with USB-C OTG adapter. I think that 1+3T doesn't have enough power for DAC. You can try changing USB CHG to off in DAC settings. Maybe it will help.
I got it to work by enabling storage over OTG and turning off USB charging in the DAC. Only USB Audio app is able to play music still. Other music apps do not send audio over the USB connection.
Is there a way to get audio output while its connected to the pc to get the audio from pc speaker? Since usb c port is commen for data transfer and audio output, I saw this as a possibilty. But I don't know the way through.
