Cannot change audio input device

Binary package hint: phonon

Kubuntu 10.10 beta + updates through 9/14/10

I recently purchased a Logitech Webcam Pro 9000 with a built-in microphone that connects via USB. The device appears in the list of capture devices when I run systemsettings and examine the Phonon configuration along with the microphone input on the motherboard. However I cannot select this device as my preferred choice for audio capture. If I highlight any of the capture options in the tree and select the Webcam 9000, the "Apply" button remains disabled.

This remains true even if I run 'sudo systemsettings' from the command prompt. I cannot change the device either as a normal user or as root.

Once again the problem seems related to PulseAudio. I removed Pulse from my system so I'm using plain ALSA. Now the entire array of input and output devices appear in Skype and the microphone works as expected when I select it from the list.

Nevertheless, I still cannot switch the default audio input via systemsettings. Selecting an item in the tree and choosing a preferred input still does not make the Apply button active.

Seems simular to Bug #769274 appeared in kubuntu 11.04

I'm the original poster, and this is not a bug. I did not see the prefer/defer buttons on the Phonon dialog box.

I'd close this "bug" if I could.

I've marked it "invalid".
