Comment 38 for bug 417778

If I add a mixer plugin to my panel, it works fine. The volume is controlled properly and the CPU does not max out.

Some time later, I repeatedly notice it has begun using 100% of both my cores.

I have an onboard sound chipset that dmixes properly with alsa. I do not use a sound daemon of any kind. I also have a (mostly-unsupported by Linux) Creative X-Fi sound card which is plugged in but unused. The plugin detects the following sound cards:

NVidia CK804 (Alsa mixer) - this is the onboard chipset that I use all the time.
Monitor Integrated Webcam (Alsa mixer) - one of my DFP microphones
pcsp (Alsa mixer) - I have no idea what this is.
Monitor Integrated Webcam (Alsa mixer) - one of my DFP microphones (dual monitors)
Realtek ALC850 rev 0 (OSS Mixer) - I'm assuming this could be my X-Fi, but it really looks like something else. In any case, I've not seen it before.

That's the list exactly as I'm given it. I haven't been able to find out what causes the mixer to go crazy. My sound card is not disconnecting as in bug 4962, but I think it may be a related problem, so I would suggest taking both bugs into account.

Thanks for all of your hard work. All of us appreciate XFCE.
