ok, what is PA _for_ then? (see below)

it doesn't do what the *mixer* is supposed to do - to *mix*
for example -
most (?) cards have two external inputs - microphone and line-in
now if there is only one volume control, how do I express that I
want to mute the microphone and set the line-in to some value?
what if the soundcard has a "boost" on/off switch which doesn't
just amplify the microphone but it completely changes input
characteristics from condenser mic to dynamic mic range?
- how is this supposed to work with "one slider rule them all"
type of control?
