this patch is the first attempt at providing an ALSA driver to Wine
it includes:
- an quick audio implementation for ALSA 0.5 interface
- a more complete audio implementation for ALSA 0.9 (buffered and
mmap:ed for DSound), eventhough still lots of stuff needs to be
implemented
on the todo list, there's:
- implementation of the remaining of the driver (mainly for the
0.9/final interface for midi, mixer...)
- enhance configuration bits. as of today, we cannot build a DLL which
will be compatible, based on what's available on the machine on the 0.5
or final interface
to enable it, change your ~/.wine/config file, in the WinMM section to
have:
Drivers=winealsa.drv
(and be sure you have alsa installed ;-)
