--- Comment #9 from Jeff Cook cookiecaper@gmail.com 2008-09-28 06:17:42 --- The patch from Adam does not resolve this issue for me. The output about no Master control remains. Both of my USB devices (external mic and mic in webcam) have only a Mic control, which, according to the source of mixer.c, should be handled separately as a Capture control (and debug messages I've added indicate that it is being detected as such, returns positive for snd_mixer_selem_has_capture_volum(elem) ), but it doesn't work. Working on a patch but I'm unfamiliar with both WINE and ALSA's source, so it will probably take a while.
