Agreed. But master and PCM are not the ways for it. PCM controls the
source and affects all targets. Master is, by my
definition/understanding of it, a control for *everything*. You should
have a way to make all speakers louder, and master is that means IMO.
And you definitely should have a single, revertable (on/off) knob to
mute everything.
There should be one setting for each channel in addition to the master
and PCM. That's similar to AV recievers work, BTW, they usually have a
master vol controlling all speakers plus a way to influence the vol of
the speakers in relation to each other.
I don't think it's a good idea to fix this in MythTV, because I have
several other ways to change the volume (lirc invoking aumix -v; XMMS)
and I'd expect them to all behave the same way.

That design can also be buggy (wrong) ;-).

Yes.

(Or pay somebody to do the coding for you.)
Well, that's true for almost all problems with Open Source software :-/.
