[arch-general] Muting internal speakers

[Nelson Marambio]

Since the change from Win 7 to Arch there is just one function I really 
miss up to now. Perhaps someone of you can help me out.

Is it possible that Arch deactivates the internal speakers of my laptop 
when I plug in my USB-headset and turn input / output to this ?

In Windows I could define the USB headset as default for in-/output so 
Win made a fallback to internal speakers only when I plugged out the 
headset again.

It would be really great if Arch was that comfortable too. I know in 
GNOME there are just two clicks to do for switching to another audio 
hardware but ... :D

Warm regards,
Nelson.
