Comment 6 for bug 471889

Result. With linux-backports-modules-alsa-karmic-generic and the stock Karmic kernel sound (as per recording/playing with Gnome sound recorder) works, as it did before (noise and offset but that's ok).

Thanks. Could you tell me which driver are in the package? Are they in some vanilla kernel? I suppose they are the drivers for 2.6.32, am I correct?

On a side note, skype still does not work. If I run it with pulse as sound driver, it sort of works for the first time, then it spews out a lot of

bt_audio_service_open: connect() failed: Connection refused (111)
RtApiAlsa: underrun detected.

and then sound is totally mangled, but I understand this is a Skype problem, not Ubuntu (although yes, it worked in 9.04).
