[plug] Sound not working

[Tim Bowden]

Hi all,

I need to get my sound working again- Just before I left work this
afternoon my boss in Sydney phoned and said he had organised a
teleconference over the web for first thing in the morning.  As luck
would have it, my sound stopped working the other day...  Not sure why.

System:  Toshiba A10 laptop, debian sarge with 2.6.6-1.
