"fixme:mixer:ALSA_MixerInit No master control found on AK5370, disabling mixer"

Is produced on wine startup, disabling my usb microphone. In
dlls/winealsa.drv/mixer.c it disables mixers that have no 'Master' control,
making controllers like this that have only the one "Microphone" capture
control unusable.
