The patch won't change my situation, nor some other commenters.  I have a
Logitech Desktop USB Microphone, comes up as an AK5370.  It has one single
control, for the Microphone.  It has no playback support at all.
# amixer -c 0 scontrols
Simple mixer control 'Mic',0

Reading the comments in mixer.c, it seems a Master control is "wanted" by the
Windows API.  I'm not sure on the exact meaning of "wanted" in this context,
whether the API will be broken if a Master control is not provided for a
capture-only device.

I'm quite happy to hack through the source code to work on this, but should the
aim be to provide a "dummy" Master control that does nothing, or should a
device with no Master control be provided?
