Hello Q!
I don't think this problem is related to a config file on a home partition.
I someties get the same issue with a few of my soundcard channels. I have got
an MAudio Delta 1010 LT.
The relevant config for this should still be asound.state (or similar) in
the /etc directory (I know the exact name has changed with more recent ALSA
versions).
I first noticed that problem, when experimenting with suspend to disk. I'm
not sure, if that was the reason for it starting or if it just conincided with
some minor bug in the ALSA version of that time.
Sorry, that I can't be of more help.
Warm regards
Julien
