I am attempting to use a StarTech 7.1 USB external sound card to get 7.1
surround in Trisquel. It should work with Belenos as it is internally
identical to this:

VLC recognizes the device, but plays in stereo instead of 7.1. I had the same
issue in Windows until I configured the device in system sound settings to
default to 7.1, so I suspect I need to so something similar in Trisquel.
However, while both the microphone and line-in on the device show up under
System Settings->Sound->Input, the device does not appear under Output, so
I'm not sure where to access the device's default speaker configuration.
Thanks in advance for any advice.
