Greetings,
Although audio support has been in USB for a while, it still has trouble
with properly detecting the built-in microphones in my Philips webcams. For
some reason, it claims there are no audio streaming interfaces on the cam,
while the descriptor dumps clearly show there are. I *think* the audio
parsing routines are confused by the fact that these cameras use
Interface 0 for the video, the AC interface is 1 and AS is at 2. My guess is
that all audio-devices tested so far have the AC interface at 0 and AS at 1,
because this is shows up in my log:
usbaudio: device 3 audiocontrol interface 1 altsetting 0 not zero bandwidth
^ should be 2!
usbaudio: device 3 audiocontrol interface 1 has 0 input and 0 output
AudioStreaming interfaces
^ again
usbaudio: constructing mixer for Terminal 2 type 0x0101
usbaudio: no mixer controls found for Terminal 2
So attached you will find 2 complete descriptor dumps (in hex format, with
some extra info) of a 2 different webcams. As far as I can tell, the
descriptors are perfectly legal...
I'm looking into it further myself, but maybe some of you have a good idea
(or a simple patch).
