Bug Description
Binary package hint: pulseaudio
Using Ubuntu 9.04 on a Dell 620 laptop.
All sound is screeching/
Sound worked on Ubuntu 8.10, after upgrading to 9.04 sound does not work.
I can make the static-ness not happen in the System -> Preferences -> Sound test buttons if I select OSS as the output, but if pulseaudio or ALSA is selected then I get static on the test. I can hear the correct sound under the static noise, but all sound is accompanied with static. I've removed then reinstalled all the ALSA and pulseaudio drivers with no luck. I assume that means this is a problem with PulseAudio or ALSA? Here's the output of lspci -vv

Have you tried the test kernel at http:// kernel. ubuntu. com/~dtchen/ ?
