I have a Schiit Modi USB DAC. I cannot get it to play audio.
What should I configure to get this DAC working?
What other relevant info should I provide? The DAC is known to be working (works fine in OSX and Windows).

I recently got mine working but I could only do so easily using pulseaudio. Use something like pavucontrol (sudo apt-get install pavucontrol) to control which soundcard to use by default.
In pavu, under the output devices tab, click on the green checkmark button lined up with Schiit USB Audio Device Analog Stereo. Now play some music and enjoy.

Like the OP, I also could not get the Schiit Modi DAC working with Ubuntu (12.04). Specifically, the device was not listed in pavucontrol. Here's what worked for me:
- Installed the 3.11 kernel
- After booting with the new kernel, my nvidia driver (and therefore video) was messed up. I needed to install the 331 nvidia driver for compatibility with 3.11.
Hope that helps.

Hello folks! I just got myself an ODAC and would like to share my setup with you guys. It took a lot of googling and I'm not sure if it was done properly, so any comments would be appreciated!
Present date: Nov. 2014. My setup: ODAC, designed by nwavguy, usb-powered, usb-dac with usb audio class 1 (UAC1). PC running Linux Debian jessie (testing), with all updates up to the present date. My main music player is quodlibet 3.2.1 compiled from source.
Identifying the USB DAC audio card. Plug the usb cable, and check the output of 'aplay -l'. Mine came out with, among other things, the piece:
The ODAC is then identified as card 'DAC', device '0'.
Disabled pulseaudio. Pulseaudio comes as a standard in many distros, but wasn't for me, and it seems to be a common thing among people (although many do like it). To disable it on xfce, open 'Session and Startup' on the settings menu and uncheck PulseAudio Sound System (or any analogous method to stop it to be run on the startup). Create file '~/.pulse/client.conf' if it doesn't exist, and add the line 'autospawn=no'. This will stop pulseaudio of being rerun when shut down. Finally, kill pulseaudio with administrator privileges, or reboot the system.
Tentative 1. Set ALSA for one, and only one stream. This setup for alsa allows only one stream to be played at time. It should theoretically be the closest to 'high-fidelity' reproduction. If a second stream tries to play, it plays muted, or bumps with an error notice. To do so, check installation of 'alsa-base' and 'alsa-utils'. Create the alsa configuration file '~/.asoundrc' and input
Then, restart alsa with the command 'sudo alsactl init' with administrator privileges, or reboot the system.
Alternative setup for player. In this way, I set quodlibet individually to output to the external dac, leaving the alsa default unchanged (hence everything else playing on the default sound output). you can stay with the default card for all other sounds, and have quodlibet as your only stream on the external dac. To do so, check installation of 'gstreamer1.0-alsa'. On Music, preferences, playback, output pipeline, add 'alsasink device=hw:DAC,0'. There seems to exists methods for other players.
Alternative for multiple simultaneous streams. I achieved playback of multiple streams (e.g. youtube video while quodlibet is still active) using the 'dmix' plugin for alsa, which remixes all streams before outputting to the external dac. One could check the alsa reference here, but i followed this post. Basically, check the installation of packages 'alsa-oss', and setup the '~/.asoundrc' file for the following
Then, restart alsa with the command 'sudo alsactl init' with administrator privileges, or reboot the system.
This concludes this post. Thanks!
Install Usb Dac Linux Support
EDIT: Tip on switching configs. Pretty basic. Set example files for '.asoundrc', like '.asounrc_odac' and '.asoundrc_dmix'. Then, when needed, just overwrite '.asoundrc' with an appropriate copy of example files (or just erase it, if you want to go back to default), and then run 'sudo alsactl init' with administrator privileges.
