thanks for your help. if not directly what components or mods would be necessary. the galaxy player would be perfect for me but i dont want to sacrifice sound quality so i need a portable dac/amp for it plus the e17 just looks sexy

the e17 needs more power then a phone or galaxy device can give via usb, you can make it work, by patching the alsa driver, and by supplying extra power. No easy fix, no firmware fix possible. Understand that?

 

Also @feiao congratulations, the E18 sounds good. what you may want to do is allow the user to chose, when he is not using the device he can switch it to "charge mode" and it will charge the phone, but when he does use it, he is forced to usb accessory mode. 

 

that way charging is still possible.

You can only switcher on your Android phone when you want to charge it. not on the USB device . 

 

Most Android phones have a build in switcher , so the micro usb pin can switcher from usb storage, usb OTG, charging , data transfer and so on,

then I see no problem.

 

Maybe I should just make a little widget that you use on the home screen to switch at a single click.

There are already some widgets that will allow for USB fast charging when connected to car chargers (kernel support required.)  I know the same can be accomplished via scripts.  One can create shortcuts that start a script with Script Manager. 

I wonder what the app Stickmount is doing exactly?  It allows for mounting thumbdrives or harddrive partitions.

So, does or does not work the USB DAO in CyanogenMod 9 or 10? Or all the output is going thru the phone amplifier?

hey guys, just thought i'd post this here: http://forum.xda-developers.com/showthread.php?t=1930664

 

it's a bounty attempting to sway a developer to introduce the USB audio (external DAC support) feature on AOKP or CM10.  so far we've raised the bounty to a bit under $600.

no it does not.  it supports a google specified method where the DAC is a USB host, not the other way around.  this requires a new class of device that does not currently exist.

Sorry, I don’t understand what your guys want.
The stock Samsung Galaxy S III can output a USB audio stream while being charged with a Y-cable.
 
"I bought Behringer UCA222 USB DAC and tested it in my car with the USB OTG cable with power from ebay that I mentioned before. It works great! And the phone is indicating a charge."

we want this support in CM10 and AOKP so that CM10/AOKP compatible devices (most of them!) are capable of using USB audio.  On the Samsung Galaxy S III USB AUO is only supported on the stock ROM/kernel.

I have a Toshiba 10'' Tablet and I'm running CM10. The E17 doesn`t work. The Usb app detects that Usb host is enabled but fails to load an specific driver

missing S3C USB driver to get USB audio working!

Yup. This functionality usually has to be implemented by the manufacturer (like in the case of Samsung and Archos).

The E17 has a buggy descriptor so it won't work. Unless you patch the ALSA driver with a fix.
