Comment 2 for bug 416832

Same here, except not quite 100%. I have Xubuntu 9.04 on 32-bit x86 and occasionally, xfce4-mixer-plugin starts using 80-90% CPU. If I have an instance of xfce4-mixer itself running, that is not affected, nor does it seem to have any effect on the bug.

I am using ALSA on a C-Media CMI8738. The bug is fairly rare and I can't tell just what triggers it. In this particular case, it happened right around the same time I suddenly lost network connectivity - I'm not certain whether that was an issue with the machine or the router. Just stopped being able to ping it at all for a few minutes. Likely a coincidence, unless anyone else has noticed a similar pattern.
