Seems it is time for things to go amiss for me
For a week or more Kmix has been misbehaving ....... locking up, using 50% CPU and generally behaving badly.
It uses the 50% on start up and also when any audio app tries to play a file .... probably video with audio too but I have not bothered to check.
Removing or disabling PulseAudio allows it to perform as it should.
Removing Pulse and cleaning out all files I found, and then reinstalling after a reoot did not help.
Alternatively, removing Kmix, and running with PulseAudio and using its volume control does not present any problems.
In addition I used VolumeIcon for a little while with Pulse and no problems, but that is not integrated with Pulse so I think that can be discounted.
So it seems there is some clash between Kmix and Pulse that I am unable to find.
Has anyone else experienced these symptoms?
In addition, on occasion, usually immediately after start up, the sound output is noisy/scratchy.
I cannot think what else I can do at the moment, so suggestions welcome.
The audio is a PCI Creative SB Live! EMU10k1 (rev 08) which works well and has not been changed.
I hope someone can suggest something ....
