it in kmixer. Maybe your webcam does the same.


Hi Jos,

It sounds very interesting.
Confess that I manipulated into Yast-->Sound a bit, in order to see if
my webcam is behaving as a sound card, but I am far to find the correct
settings and how to be sure that it is really being seen as a separate
sound card by the system.

How did you proceed to make work your webcam?
Which webcam model is it?
Which Linux Distro / kernel are you using with this webcam

BTW in kmix I see USB Video Camera window separate settings and I am
able to select the available options and adjust the input gain.

I have a Trust 6250X webcam and I'm still on 11.0 (kernel
2.6.25.20-0.7-default)
for reasons I won't go into right now. :-)

To make the microphone work I plug in the camera and restart kmix (if kmix
-the
speaker icon- is not in your system tray you just start it). Click on
kmix>mixer
to bring up the big mixer panel. In the top right hand corner you will see a
drop down arrow next to the make of your current sound card. Click on it and
you
get a drop down menu with all soundcards present. Choose your webcam, unmute
the
input, raise the volume to 80% and Bob is your proverbial uncle. For reasons
unknown to me the volume is always reset to 0 when I unplug the camera.

I see exactly what you reports about kmix settings.
USB Video Camera is showed, along with its controls; but no chances to
see any sound through kmix level meter, nor to ear recorded audio
through krecord.

TOTAL FAILURE!

sometimes you must work under adverse conditions... like a state of
