No sound in 12.04 Beta

[chris hallsworth]

Hello all.
I wish to report the lack of sound in Ubuntu 12.04 Beta. I installed it 
via Wubi last night our time. Everything seems to work except the sound. 
For a blind person who relies on the use of Orca, I feel this should be 
addressed as a matter of urgency. Previous versions of Ubuntu I could 
get sound. My laptop is an Acer Aspire 5735 and the sound chip is the 
Intel HD Audio onboard, sometimes called High Definition Audio.
