I just noticed that in mythtvsetup 'Capture Card' screen, there's a
tick box titled:

Do not adjust volume

that has the help comment "Check this option for budget BT878 cards ..
that require the audio volume left alone"

It doesn't seem to be checked by default, so maybe you could check if
setting it stops mythtv messing with your volume..

Just a thought.
