Don't know, but nothing comes up on a somewhat cursory scan of the man 
page, and nothing in sound.html seems unquestionably relevant; there are 
a few things about volume filters, which might help as a workaround but 
reportedly decrease audio quality and regardless aren't what you asked 
about AFAICT.

About what I'd guessed.

Kernel version is part of the general information requested in every 
case, but the other two may be a bit more of a problem. As I said, my 
sound card is actually a chip integrated into the motherboard; I can 
give the manifacturer and model name/number, but I've got no idea what 
driver is being used, and the only way I know of to even try to find out 
more than is available through lspci -v involves restarting the system 
and reading the startup messages, which is scarcely an ideal solution. 
^_^ dmesg is of no use in this case, since the buffer it reads has been 
getting flooded with network error messages from both known and unknown 
causes, and the actual startup messges are long since gone.

About what I figured... the trouble is A) that I'm not always as good as 
I'd like to be at knowing what is/isn't related and B) that providing 
just what I can determine to be related is frequently less than what's 
requested by the documentation, and I don't like to go under spec 
without knowing exactly what I'm doing. ^_^

I'll go nag my brothers again about testing to see if the problem occurs 
in the same way on any of their systems... don't know how successful 
I'll be, however.
