This was my question in IRC =96 and thanks to those investigating on my
behalf. I=92m a total Linux newbie. Let me do my best to explain:

I=92m on KXStudio, where all audio goes through Jack (as I understand it).
When I switch my firewire device (Phonic Firefly) on, jack recognizes it
straight away and runs all audio through it instead of my onboard PCM.
That=92s great! However, if I want to turn my firewire device off and have =
all
sound go through the onboard PCM again (and subsequently my built-in
computer speakers), this doesn=92t work! When I turn the firewire off, jack
simply stops completely and I have to =91force restart=92 a couple of times=
to
get sound out of my speakers.

It=92s not the end of the world =96 I just wondered if it=92s fixable as Wi=
ndows
was able to automatically switch between my firewire and onboard cards with
no problem. I=92m a graphic designer by trade and if I=92m just listening t=
o
music I don=92t want to use my firewire device to do so. But if inspiration
strikes spontaneously I just want to switch my firewire on, lay down some
recordings, then turn it off and go back to using onboard audio=85 preferab=
ly.

Sorry if my terminology=92s off =96 just say if I can explain myself better=
.
