winealsa: 6 Channel Audio

[Jonathan McCrohan]

Hi,

Using foobar2000 (Wine 1.3.31) to output 6 channel audio via WASAPI, I
get an error in foobar2000, and the following Wine errors in the terminal:

fixme:alsa:AudioClient_GetMixFormat Don't know what to do with 10000
channels, pretending there's only 2 channels

However, when using a patched version of Wine with hardcoded support for
6 channel audio, foobar2000 6 channel audio works correctly (patch
attached). While this works, it is just a hack and doesn't fix the
underlying issue; the additional 9,994 audio channels. This also merely
just changes the error message from 2s channel to 6 channels:

fixme:alsa:AudioClient_GetMixFormat Don't know what to do with 10000
channels, pretending there's only 6 channels

Would someone with a better knowledge of Wine and/or ALSA be able to
assist me in tracking down the source of this bug?

Thanks,
Jonathan
