[Qemu-devel] gsoc idea

[Kővágó Zoltán]

hi,

i'm thinking about doing a gsoc this year, and i'm interested if you 
have any opinions on my idea. (i hope i'm not late for this...)

currently the audio system in qemu is limited to 2 channels (stereo) 
sound. also it mixes all sound (if there's more than one sound card) 
into a single stream, you can't send them to different physical sound 
cards for example. if you need something like that, you'll have to 
either pass-through a sound card (but then you can't use it from the 
host), or use pulseaudio/jack/etc to send the audio over the network 
(which is problematic in case of a windows guest)

imho the audio subsystem should be rewritten to support any number of 
audio channels. also, the current global mix everything together into a 
single output method (along with it's environment variable based 
configuration, since it only allows global options, not per-device) 
should be replaced, with a system similar to how network or drives works 
(i.e. each virtual sound card would be connected to an audio device, 
with their own options)

is it a viable idea, or i should scrap it altogether?
