2.6.12 sound problem

[Stephen Clark <stephen.clark@earthlink.net>]

Hello,

I recently upgraded my laptop, HP Pavilion N5430, from a 2.4.21 kernel 
to 2.6.12. As a result of
doing this my sound no longer works correctly. It plays the same thing 
repeatedly some number
of times - if it plays at all.

Any ideas on how to debug this would be appreciated.
Thanks,
Steve
