Some applications seem to rely on the pre-Vista behavior, and I'm trying to determine if Rosetta Stone is one of them (I doubt it; otherwise Windows users would need to set compatibility mode to run Rosetta Stone). We might need to change Wine's implementation to match Windows 7's WinMM when a program is run with WinXP compatibility mode. I haven't investigated the differences yet. This would obviously break applications that rely on Windows 7's direct WinMM implementation, but I don't know that there actually are any.
SB16, SB Live! , AC97 codec and those HDA codecs with 6 or more channels DAC usually have a amixer
Are you using a notebook with HDA codec has two stereo DACs ?
mixer is actually core of winmm and a bridge between waveout, wavein, aux, midi, mci devices (compact disc, laser disc player)
For playback sources of mixer are waveout, cd, aux (wave blaster, radio) video(tv card audio) midi(fm synth, wavetable synth), line-in, mics and destination are speaker and headphone
For capture, wavein is the destination which has sources (e.g. ext-mic, int-mic, line-in, rear mic and front mic)
