Hi guys, i am just working through my install of Kubuntu 810 and have a system up and running. The issue i have is that i cannot unmute the PCM output within ALSA and as such get no audio over HDMI. I have followed all the guides here and am running 1.0.20alsa with the HDMI output listed. The attached screen grab shows that even from alsamixer within konsole i dont have the option to unmute PCM.
I have also tried amixer set PCM 90% unmute but with no change to the PCM mute status.
Does anyone have an idea how i might go forward from here?
