Hello everyone!

I installed ubuntu few days ago and got everything working,
except digital output in my integrated Realtek ALC850 8-channel Sound card.
I have tried to modify alsamixers settings, but still the problem remains the same.

I have tried it with several programs like XMMS, Mplayer, Xine etc..
In XMMS i have put Output plugin: Alsa and audio device: hw 0,2 => Nothing.
Here's my settings:

There is a light coming from my optical cable. Everything is working in Windows, so this is not a HW-problem.
Thanks for the answers!
