I just got a Schiit Bifrost in the mail (
http://schiit.com/schiit-faq/about-bifrost). I want to use it via USB.
The Schiit Bifrost uses a C-Media 6631, I can see it when I do an lsusb:
agd@minerva:~$ lsusb
Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 051d:0002 American Power Conversion Uninterruptible
Power Supply
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 004: ID 0d8c:0304 C-Media Electronics, Inc.
Bus 001 Device 003: ID 11b0:6566 ATECH FLASH TECHNOLOGY
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Here is a gist of an lsusb -v: https://gist.github.com/1335351
I can also see the device in alsamixer when I hit f6 and try to select it,
its shows up as 1, right after my intel onboard.
When I select it in alsamixer I get an error: cannot load mixer controls:
Invalid argument
I'm using this with ubuntu 10.04:
agd@minerva:~$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.21.
agd@minerva:~$ uname -r
2.6.32-34-generic-pae
Any help would be appreciated!
