Comment 16 for bug 400629

I have the same sound card, same issue, but there's a "workaround" using alsamixer:
-start alsamixer from terminal (is there an easy way to get a gui?)
-just unmute the IEC958 0 track using the "m" key

I have no idea how to have this set up automatically.

Btw, the only way to get access to the sound card's equalizer is from alsamixer, which is absolutly not convinient.
I really hope we will get back full access to every options from a simple gui.
