Comment 13 for bug 584337

I have very similar problem on my Dell Latitude D620 with Lucid. A workaround with the sound seems to be to delete the pulse directory (i.e. rm -rf ~/.pulse) shut down and restart. The only way to shut down after sound failure is from the command line (i.e. sudo shutdown -h now). I have had the problem ever since upgrading from Hardy to Lucid in April. I have never been able to consistently reproduce. The problem may have something to do with power management. If I start on AC, pull the plug and run on battery for awhile and shut down, the problem is likely to recur. I have never seen the problem on a Dell Dimension Desktop that always runs from AC. I seldom if ever see it when running the Latitude laptop from AC for repeated startup and shutdown, Before a recent kernel upgrade (I do not remember which one) CUPS and the VirtualBox kernel module would not load properly after the restart. CUPS and VirtualBox load fine now, unaffected by the sound driver problems. I believe there is something wrong in power management and the kernel.
