For quite a long time now I have been trying to get my digital out on my Terratec Aureon Space 7.1 to work. The analog out is working but since I only use the digital out it isn't sufficient for me.
Because I was hoping to get an answer as to how to enable the digital out I posted several emails to the alsa-user mailinglist. Although the answers I got helped me to better understand how Alsa works I still haven't received the answer I was hoping for: what should I do/enable to get sound through the digital out? Since the information I might need is a little more technical than just a "run this tool" or "copy this file" I figured that I might get a better answer when I post my question on this mailinglist.
I tried playing with the mixer to increase the volume and fiddled with some other controls but no luck there. I have also tried iecdump and iecset but these tools also didn't provide me with the necessary results. The problem will probably have nothing to do with the drivers but it looks like I have to flip a few bits in order to activate the digital out. Could someone please provide me with the correct bitmask that I need for enabling the interface?
I have included some further info below that might be helpful.
It seems that control.18, control.19 and control.20 are the most interesting
controls. But I don't know what bitmask I should use to enable the digital
out and I'm a little afraid to just start playing with the controls. I don't want
to break anything by writing invalid values to it.
Control.16 also seems important but since it's on by default I don't think
that I have to worry about that one.
