just a prefice --- yes, I've tried reinstalling Clementine...
...first, how I got into this mess...:
What happened is I did a keypress combination trying to set up a screen effect trigger (I think it was Ctrl f11 or f12). This blanked my screen and I knew of no way to get out of the situation. Doing a CTRL-Alt-Del didn't trigger a logout. I pressed the power button to force a logout but when I got the screen back, the text showed that the logout process stopped somewhere. So I forced a shutdown.
On restart, PCLOS reports that my mainboard sound isn't working so it says "falling back to..." the same device! I then get the KDE startup sounds.
A device management window pops up with what I believe to be the mainboard sound device greyed out and asks if I want it removed. There is another copy of the same device in there that is not greyed out.
WHen I try to play sound files through my regular speakers via clementine, it reports "Connection refused".
When I try to play a youtube video, I get no sound.
Pulseaudio is still set as active. I see no changes anywhere in any settings.
If I use Amarok, I get sound through my speakers ok.
Thanks in advance.
Adding the following:
The device that still works is the burr-brown usb speakers.
The device that it reports as failing is HDA Intel PCH (alc892 analog). It then reports it is falling back to the same device! This is at KDE startup after a reboot.
"Sound and video configuration" shows a greyed copy of HDA intel and one not greyed. Ditto with burr-brown.
