Correct, however the result is the same (doesn't work) with both waveout and 
dsound interface, because of said hw limitations.

Just to clarify - the device name *was* hardcoded to "hw,0", the patch makes 
it possible to specify it in the configuration file.

Well, it is identified at run time by the current code, and the driver tries 
to use it, but it doesn't work. So I added the option as a way to tell 
winealsa not to use the mmap interface. Here is the error that I get if mmap 
is enabled:

trace:wave:wodPlayer_WriteMaxFrags Writing wavehdr 0x4122c260.0[32768]
wine: pcm_plugin.c:491: snd_pcm_plugin_mmap_commit: Assertion `size == 0' 
failed.

Those ALSA assertions are pretty annoying, no way to inspect the error or to 
bail out :-(
