Centos 6.2 Skype no audio through Logitech QuickCam Pro 9000


I have searched the forums and not gotten a clear solution to this problem.

I have a Logitech QuickCam Pro 9000 plugged into my CENTOS 6.2 workstation.
The video component works just fine, but the audio does not.

I can't seem to get the microphone to work on the camera under Skype (or any other application).
My guess at this point is I have misconfigured my sound settings and can't figure out how to get them back. (Clicking on 'default' under System settings doesn't seem to work).

I've only installed alsa and not pulseauido.

I'm running CENTOS 6.2 (64-bit) kernel: 2.6.32-220.17.1
My desktop environment is KDE.
Hardware: Intel DP67BGB3 + i7-2600K
I'm using the built-in sound card which seems to work fine for everything else.

Should I install/use pulseaudio instead of alsa?

Any and all help would be appreciated.

Thanks in advance

Then you need to change the sound input device to the logitech webcam. Doesn't kde offer some setting for sound input device?

See if this still works.

Thanks for the reply.

I can start up the System Settings-->Multimedia option I can see my Webcam's mic under "Audio Capture". It's listed as "USB Device 0x46d:0x809 (USB Audio)" But it's greyed out. I can't seem to make it active.

I removed pulseaudio an now I'm using just ALSA for sound.

Any suggestions?

I solved a similar problem 15 minutes ago. I have a regular microphone (Shure SM-58) and physical mixer (DJ style) going into my 1/8 " microphone jack on my computer. That is the microphone I want to use. I added a Logitech 9000 camera/microphone. Everything was fine until I updated things 3 weeks ago. From then on, everything BUT Skype kept hearing my regular microphone, but Skype would ONLY listen to the Webcam mic! The Skype settings had no options and the KMix (I, too use KDE) capture device listed both as options. All programs I tested would respond fine to the selection of either of the two sources - except Skype. It would ONLY hear the Logitech webcam microphone.

Finally, I went to the KMix --> Settings --> Audio Setup (which launched Phonon - KDE Control Module for me)
In the left window, I selected "Audio Recording --> Recording and in the right panel, two selections appeared. (one was the webcam and the other was my sound card)
I selected my soundcard and clicked the "Prefer" button at the bottom of that window frame. It moved my sound card above the webcam.
I saved things and Skype worked with my sound card.
When I selected the Webcam and "prefer"red that one, Skype listened to the webcam (and not the sound card!).

I suspect that if you try this, you should be singing to your friends in no time.

Good Luck.
