Default Sound input problem after F15 update

Hi --

I updated Fedora 15 a few days ago and now I don't have sound input.
The input device is a Hauppauge tuner and it is recognized:

[ 8.738997] snd_bt87x 0000:09:01.1: PCI INT A -> GSI 17 (level, low) -> IRQ 17

Pulseaudio volume control shows the BT as an input device, but the volume
display doesn't show anything. The playback tab only shows "System Sounds".

There is also an internal sound card which shows up in pulse audio. When
the audio source is plugged in to this input, it does show up in the pulseaudio
volume display, but there is no sound output.

Playing audio from Rhythmbox works OK. (When this is running, the playback
tab shows Rhythmbox.)

Any help?
