Could the cause of the original bug actually be flash somehow? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

There is a workaround, a shot in the dark in my view, but it seems to work... See bug #679155 . In short, kill kmix (I used ctrl+esc and sent it a TERM signal). Then, open a teminal window, and run kmix like this:- shell$ KMIX_PULSEAUDIO_DISABLE=1 kmix If you amend your .bashrc file with export KMIX_PULSEAUDIO_DISABLE=1 That might very well fix the problem permanently (but I haven't tried it yet). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Richard, as you can see from Comment 2, I have already noted that disabling PulseAudio prevents this, however, as noted in Comment 3, Flash then starts having severe sound problems - if a flash video is left open for a certain amount of time, the audio no longer plays back properly. Instead, you get a part-second loop that jumps forward every 5 to 10 seconds. This does not happen with PulseAudio enabled, but as you have noted, one CPU core runs at full throttle constantly.

I did note all you mention, but I don't actually disable anything. I think that setting the variable merely tells kmix to ignore pulse audio. FWIW I have watched a BBC TV programme (which uses Flash) from end-to-end with no problem using the technique I describd. What is /actually/ going on here I have no idea! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I would speculate that kmix is looping/polling something in a tight loop and this is mopping-up all the available CPU; but this is a bit fatuous because to any programmer this is fairly obvious. Without downloading the source and attempting to debug the program myself, I think this has to be left in the hands of others with greater insight than me! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Curiously, I stumbled across another way of fixing this though, and it involved deleting some files relating to kmix under the hidden .kde4 directory structure, and this fixed the problem. I wish I had noted exactly what it was now! This wasn't a problem I ever found a way of re-creating at will. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I left open three youtube videos, each played part of the way through, without skipping ahead (as in the videos loaded start to finish) and with no other tabs or extensions loaded. Each video was between 10 and 20 minutes long. When I came back in the morning and tried to play them, the audio playback would briefly repeat in a continuous loop perhaps one second long and then skip ahead somewhere from to 5 to 20 seconds and then loop again. This is how this bug exhibits when NOT using PulseAudio (I have it deactivated). If PulseAudio is enabled, one CPU core gets pushed to 100% by KMix as per the original report. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

If you're using pulse, you get a core locked at 100%. If you're using Alsa, you get stuttering. So I'm going to suggest what happened to you was not a fix.
