OK, this could be some side-effect of the analog low-current mode. Or, it's a
logic failure in the current driver code.

In anyway, I fixed some codes and added a new control to enable/disable the
analog low-current mode. Try OBS alsa-driver-unstable-kmp in
multimedia:audio:KMP repo. (It's *not* alsa-driver-kmp; there are two
versions, one from the current snapshot and another from my devel snapshot; the
unstable one is the latter.)

If the noise occurs after installation/reboot, try to turn off "Analog
Low-Current Mode" enum via "alsamixer -c0". (Also check with turn this
"Enabled", too.)

If this version solves the problem, I'll merge the fixes to the upstream.
