View Full Version : [ubuntu] No sound after motherboard upgrade...

May 26th, 2011, 02:41 PM
I'm having a world of trouble getting sound working via optical out on Ubuntu 10.10. It was working great until my motherboard died and I had to replace it, since then I haven't been able to get it working.

I've managed to get to the point where my AV reciever realises there is a PCM signal coming in when I play a WAV file via aplay. However, no sound actually comes out. I've unmuted and turned everything up that I can see in amixer and alsamixer, with no success. I also tried via an Ubuntu 11.04 live CD, with the same results. The sound card itself is being picked up fine in aplay -l

Any ideas would be greatly appreciated...
