Actually, PA does control the volume to a certain degree. Weird. It seems that
by default, it chains a software controller and the "Speaker" mixer together.
So from 0-33% I get software control, and from 33-100% I get the Speaker
control (which naturally doesn't do anything on the optical output).

PA seems to base that decision on the (wrong) dB values that are reported to
it. I haven't quite figured out who to complain to about this issue tho.

Interestingly, if I set ignore_dB=1 then PA falls back to software-mixing only.
That actually seems like a simpler workaround ten yours, Tanu :P
