Yes -- though I don't know what I'm doing and wasn't aware of it:

root      2210  0.0  0.0   8348  1080 ?        Ss   00:43   0:00
/usr/sbin/ld10k1 --pipe_name /var/run/ld10k1/ld10k1.socket --daemon
--pidfile /var/run/ld10k1/ld10k1.pid --logfile /var/log/ld10k1 --card 0

Could this be the cause of the vanished mixer controls?

Apparently -- I stopped ld10k1 and unloaded and reloaded alsa modules,
and the problem is solved:

I tried, but it got rejected as too large. By the time I got the
rejection, I found the problem was solved.

Why does ld10k1 have this effect on the mixer?
