Hello LA land!

I got a Startech USB audio device based on the C-Media CM6206 purely in the
hope of being able to use its S/PDIF input under JACK. It runs JACK just
fine, I just don't know how I might access the SPDIF input (or even the
line-in, just out of interest) from under JACK?

When I run alsamixer and switch to viewing the capture ports of the cm6206
there are 4 capture channels - PCM, Line, Mic and S/PDIF In but under JACK
I only get 2 capture ports which are the L and R analogue mic input
channels. I can also see the light emitting from the S/PDIF out port so I
am confident the S/PDIF should work and hopefully under JACK.

I'm running AV Linux 6

arecord -l
