Hi all
On returning from a greatly needed break :-) I found myself in posession of a "Logitech Quickcam for Notebooks Pro II" <takes breath>. A very nice USB camera, it also includes a microphone and a simple echo canceller (and a cute face tracker and video effects package :-) ).
No problem with the video side under any apps, no problem with the audio side under any apps, except under rat. Rat refuses to see it, even when it's the default microphone device. I've seen this problem mentioned a few times before, dating back to at least 2002, with no resolution. The USB Logitech headset (mike plus earphones) I normally use works fine with rat.
My guess is that rat is looking for a full duplex audio device. The camera is audio input only by definition. If this is the likely cause, is there a hack around it (can I run an instance of rat with "input only", independently of an "output" rat?), or a feature request looming to have rat cope with devices like these? i.e. independent audio input and output devices. Or an earlier version of rat that doesn't check for full-duplex? Currently this is on Windows, but I'd imagine the same thing will bite me on Linuxen.
Thanks!
Cheers,
Markus
