May I ask, is there a particular reason why you do not connect the computer to the monitor by way of an hdmi cable?
My card does not have HDMI out, just DVI and d-sub.
Perhaps I have an earlier or budget version of the card? I did not even know it was possible to get sound over DVI cable. I had to boot into windows once and heard startup sound, thought that was funny since I had the speakers shut off. And realized it was coming from the TVs speakers. Then I had to use windows another time to play a dvd with Powerdvd and thought it sounded better than my cheap speakers.
I think you might be best served to use task-pulseaudio-remove to uninstall PA after turning it off in PCC .... if you had installed PA using the task-pulseaudio meta package to install it in the first place.
Reboot, and ignoring the state of the sound system, install it again using task-pulseaudio. In addition ensure that pavucontrol is installed.
Enable PA through PCC and immediately reboot.
When rebooted, launch pavucontrol and in the Configuration tab see what sound cards are available to you.
Your HDMI should be there in addition to the internal sound card.
Play an audio file and go to the playback tab on pavucontrol ...... there you should be able to choose through which sound card to play streams from whatever application you are using.
The above scheme has not failed here on some 5 different PCs and two laptops.
Don't assume that any part of the above sequence has been done properly up to now.
Do it again as above .... it should work properly.
If the above doesn't work then maybe referencing this thread could help ...... bearing in mind that its content may be somewhat out of date by now
I did uninstall with task-pulseaudio (had installed it that way) then repeated the install (including pavucontrol) and rebooted in between everything and turning on pulseaudio in CC and rebooted again. Same "connection failed" when I go into the pulse audio control.
I am quite sure this has something to do with whatever I "permanently disabled" when I initially installed PCLOS on this machine. I had to do the install a couple of times when I screwed up things that weren't worth unscrewing at that early stage and each time on first boot a message came about disabling something in the sound to prevent problems and each time I said sure because the sound was working fine that way (through the speakers, I did not know I could get it through the TV).
When they say permanently disabled, yikes, they mean permanent. Wonder what it was? I go through Tex's troubleshooting thread there that you linked to. The two config files are correct (when enabled in CC) and the symlink is pointing to pulse folder. So this is a bust. I am hopeful I will get the message again when I install 2011 on here in a spare partition. If I get the message I will not choose to disable and see if I get anywhere with pulseaudio. If I do, I may have to install 2011 on my main partition unless we figure out what the heck I disabled here and can re-enable.
