Sound is a problem in ubuntu-11.04.

Asked by chandru

After first installation, sound seemed ok. But webcam was not working. Installed skype. Sound on skype was ok but there was NO video. On suggestion fom a forum member installed cheese. after this video on skype is ok as also recording vid through camorama or cheese. BUT sound went haywire. Cannot figure out if it is a connected problem OR a coincidence. Sound recording comes out with very bad backgroung noise. NO SOUND IN SKYPE. Where or What is the problem? Went through sound trouble shooting suggested at https://help.ubuntu.com/community/SoundTroubleshootingProcedure.

try:

killall pulseaudio; rm -r ~/.pulse*

Then wait a few seconds, the sound service will restart and may start sound again

THANKS actionparsnip. Problem is solved. However, I also found that there was a lot of background noise. A bit of footling around made me realise that there was a problem with 'mic boost' and Mike connection. Once I set these right, sound is hunky dory.
Thanks again
