[alsa-devel] Audio only I/O on audio-video things.

[Tom Watson]

In my musings, I bought a video input device that by its nature also has audio
(stereo) inputs (the video was baseband NTSC/PAL).  I was wondering if one
could configure one of these devices to be an 'audio only' and be used with
ALSA?

I understand that there might be a conflict with which set of drivers (V4L, or
ALSA) latches onto the device, but I could control that thru some configuration
file.  I just need a "cheap" stereo audio input device for my laptop, and since
I already have the video unit, and it HAS audio inputs, I thought it might
work.  The capture device is USB if that matters.

Am I dreaming about this being able to work?
Is the audio samples that are generated by such a device other than 16bit PCM?
Has anyone done such a thing (I don't see it mentioned much)?
Any other thoughts?

Thanks.
