Python audio output switch

[Pan Xingzhi]

Sorry maybe I didn't describe what I need clearly. Yes they're inputs. 
Actually I need a switch to 'hook' them to line out so when I switch, a 
mp3 file is played, or an external CD player is played, or what I'm 
talking is played.

Thanks anyway. I'm checking ALSA, though maybe I'll have to write sth in 
C :)
