I’ve written an SDL audio driver called alsadma which uses DMA instead
of read/write with ALSA.
The work in progress is at
http://www.skynet.ie/~airlied/patches/sdl/sdl_alsadma.diff
and is against current CVS.
It isn’t finished, and probably needs a lot of work on error handling…
Just throwiing it out there as I’ve a few other things to do and might
not get back to it for a while…
Dave.
