USB mic produces garbled output in System->Preferences->Sound Using Pulseaudio

[Tristian]

I have a Logitech Quickcam STX. I also have Intel HDA provided by Realtek ALC883 drivers.

My webcam includes a USB mic, and it records fine when ALSA manages sound input and output. When I turn on the Pulseaudio server and set the default source to the usb mic via padevchooser, Gnome Sound Recorder also records fine from it.

What fails to work properly is the following:

Ensure that the usb mic is set as the default source for pulseaudio (I did via padevchooser).
Go to System->Preferences->Sound
Ensure all inputs and outputs are using Pulseaudio
Run "Test" for sound capture.

What happens to me is that 1 second of garbled recording from the mic is played live, then silence.

What should happen:
When I hit test, I should be able to hear myself speak through the mic.

I am using Hardy Heron 8.04

I did some searching, and it seems to be the same as this issue.

I have attached a log with the message that play when the test is engaged.
