Sound card woe

[Kush Singh]

I had problems with hoary and nothing seemed to work (i tried all the 
permutations/combinations as given in the wiki and the ubuntuguide etc). 
Then when breezy  was launched formally in october i created a fresh 
install in another partition and the system worked perfectly (there was 
no sound problem). I also have the sound card integrated into the 
motherboard.

Incidentally i had used the hardware reporting system both times (from 
hoary and breezy) to let the ubuntu team know the hardware used by us 
(See applications menu-- system tools--ubuntu device database) This 
reporting of the types of hardware being used gives a great advantage to 
the developer teams as problems are fixed in newer versions and must be 
made an automatic feature.
