Flash the zip in CWM to enable USB Audio.

It works its just a bit tricky to get enabled. You may have to reboot the device to get it working.
Also if you have under 50% battery life the USB sound dongle will cut out. So make sure you have plenty of battery life.

MX Player works better playing videos then QQPlayer, but the sound with MKV files cuts out. On the QQPlayer the sound works fine.

The version of MX Player I tested was 1.7.40 for Froyo/Eclair.

Mediaserver doesn't work on the NST so any MP3s you add won't show up in Music players. To get around this use ES File Explorer built in music player to play local MP3s.

What's going on under the hood here?

I'd like to get USB audio working on my system without using someone else's kernel, so if you could tell me what to change in mine, I'd thank you.

What other files, apps and such are necessary (so that I can add them by hand instead of flashing)?

Just unzip the package and have a look. The only thing that may not be obvious is you need to remove /system/lib/hw/alsa.zoom2.so

Apart from that you can see the files and apps that get added just by looking inside the zip.

The main files needed are:
  • /system/lib/hw/alsa.default.so
  • /system/etc/asound.conf
  • /system/app/UsbMode.apk this is the app that enables host mode. Needs SU to be able to run.
  • Plus the kernel.

Yes, thanks, I did that already.

I guess what I'm really asking is this: what do I need to add to my uImage and/or uRamdisk to allow USB audio? I'd prefer to just modify my kernel instead of overwrite it with a whole different one.

Not sure where to get the audio sources for the kernel from. I just grabbed this: http://forum.xda-developers.com/show...&postcount=164
It has everything I need.
  • FastScreen
  • MultiTouch
  • UsbHost
  • UsbToCom
  • UsbSound

@pinguy1982, here's the kernel I'm using: http://forum.xda-developers.com/nook...7/post54803848

The specific uRamdisk I have I also modded to mount /boot as read-write during the boot sequence, in case that matters.

The ideal thing for me to do would just be to add UsbSound to that kernel, if I can, and then release it for the Nook Touch Glow. I don't think I've seen an NTG UsbSound kernel yet, so that should be useful.

@Renate NST, can you help?

Just tested it with the your uRamdisk. It works fine. Haven't tested this with the Nook Touch Glow yet. So unsure if it works with it or not.

Some apps didn't work with the sound so I have updated the USB-Sound package with a new sound engine.

Would you give me a quick run-down of the hardware required for USB sound and how to use it?
