I think the problem stems from the alsa default going to a different output channel and I could not fathom out from the wiki how to change alsa to use the correct channel apart from the suggestion to add a few lines to ~/.asound but when I used either of the two suggested sets of contents for that file then KDE became unhappy - so if there is a way to get alsa to default to the hdmi output channel (0,7) in a different way then that would likely give me a working solution. It "should" be possible but I don't know enough about the intricacies of alsa to know how to do it - and it seems the wiki does not contain enough info for me to work towards that (or I am too stupid to understand the wiki!) I could try pulseaudio - and if I can't get a solution with pure alsa then I will go that route - I have used pavucontrol in the past to run sound - but it is still a challenge to solve this within alsa - and it "should" surely be possible? -- mike c
