Booting the 2.6.22-12 kernel alleviates the problem; audio works
normally with this kernel.
I have the latest kernel 2.6.22-14 packages installed:
[EMAIL PROTECTED]:~$ less /var/log/dpkg.log | grep image
2008-02-05 12:53:21 upgrade linux-image-2.6.22-14-generic 2.6.22-14.47

2008-02-05 12:55:55 status installed linux-image-2.6.22-14-generic 2.6.22-14.51
