Hmm,

are you telling me that normal applications will already automaticly use
dmix ? Its a pitty my soundcard (SB Live!) can play so many streams in
hardware at once, so I dont realy know if alsa is doing dmixing *on*the*fly*.
But I did *think* that if you had a cheepo laptop, you couldnt open 5 xmms
and 5 xines and start playing back with all of them - I could be wrong of
course. The thing Im quite certain of, is that there is no dmix jumping in if
you try to run 2 playback oss apps through the oss emulation layer of alsa -
this will give you trouble if your soundcard cant play two streams in
hardware.
Then there still would be the point with dsnoop - I _know_ it doesnt work on
my soundcard to open two instances of TeamSpeak (voice communication -> full
duplex) - and be able to talk and hear on both...this is because the capture
device is taken.
Is there anything being thought about of something like the automagic
dsnooping I was talking about ? It realy would be nice to be able to use
multiple applications of teamspeak on *normal* soundcards like mine...

Peter
