Thanks for the wmiirc_local.py example. I used it as a base for

before asking, but I can't, I'm getting headaches. Would you
mind posting yours?
Sure, if you really want it. The alsamixer module isn't mine,
though, and it'd buggy. The only reason I use it is that some
programs change the PCM mixer value and you can't access it via
OSD.
The Linux version is attached.
