Here's a link to the Gentoo ALSA Guide:

If you haven't been through that, maybe it'll provide some tips to
double check your installation.
Thanks for the link - that's what I had used to install the sound software though.

Randy,
Are you using the built-in kernel drivers or alsa-driver/alsa-utils from
portage?
I am using the built in kernel drivers to avoid the pains that come with reemerging when a kernel recompile is necessary.

I think this is actually a hardware issue, but the strange thing is that I haven't been able to reproduce it lately. This machine is a Sun Ultra 20. It has a headphone jack on the front, and an output jack for speakers in the back. Being that I work with others in the same room, I thought, "Hey, I'll use the headphone jack." Using the headphone jack is what seems to be problematic. When I plug the headphones into the headphone jack on the front of the machine, it is a very noisy signal (and I think is what triggered the mute-unmute phenomenon). If I plug my headphones into the back of the machine (which they won't reach unless I sit under my desk :)) the signal sounds clean. Oh well, guess I'll have to invest in an iPod for work ;)

Thanks for the tips though!
