Today I did an `aptitude full-upgrade' on my sid machine and during the
process, kernel-image-2.6.30-1-686 was installed. Now if I boot the
2.6.30 kernel, there is no sound. None of the applications give any
error. The volume controls are all normal. Just the audio is missing. If
I boot the older kernel (2.6.26), the sound comes back. How can I
diagnose the problem?
I am attaching the relevant output of lsmod and lspci. What other
information should I provide?
Thank you,
Raj Kiran
