sound problems after update to Hoary

[Pere Quintana]

Hello everybody,

Two days ago I upgraded my Warty to Hoary. I am using a IBM ThinkPad
R51 and everything worked well under warty. With Hoary I have some
little  problems with sound that I think are related.

1. I can listen to ogg and mp3 files with no problem. Problems arise
when using, vlc to watch videos, I can see images but I cannot hear
anything.

2. Under warty I used warty with no problems. Now when I try to call
or people call me it just doesnt work. The programm does not crash but
when I receive a call I cannot take the call.

3. Mplayer does not work properly (I cannot even see images)

4. Whe I start Audacity it displays the following message:

"There was an error initializing the audio i/o layer. You will not be
able to play or record audio.

Error: Host error."

I hope all these are different faces of a simple problem.

Thanks for your help and for making ubuntu such a useful distribution
