--- Comment #15 from Jeff Cook cookiecaper@gmail.com 2009-05-03 02:34:24 --- This is my only experience with either WINE or Windows hacking, so take it with a grain of salt, but when I looked through this code, it appeared the easiest way to get things working is just to create a dummy Master control. Lots of the ALSA code seems to expect and depend upon this, so it'd be easier than to map things like that than not, and I assume that's what Windows expects, so we'd want to present it with a similar interface. I have the exact same mic and had the exact same issue.
Someone with ALSA experience can probably find this better; I got hung up on some ALSA-specific things and basically decided it wasn't worth it when everyone in the Linux sound programming IRC channels mocked my plight in having to figure this out with ALSA. Apparently it's not a very popular system.
