System freezes when inserting a CD/DVD, suspect sound drivers

Asked by Marcin Chady

I've been running Ubuntu 10.04 quite happily for about a month when out of the blue it froze on me while changing something in the Rhythmbox music player. This was surprising, because I had been running the player without a hitch pretty much since day one. The only significant change that had happened to the system immediately before the freeze was that I installed Arista and Audacity.

I've had additional issues after rebooting the system (#119318), which have been solved now, but the original problem remains. The system freezes sporadically and the only way to get it back is by a hard reset. There is no obvious pattern to it, but I suspect it is more likely to be triggered by multimedia applications, such as Brasero or Rhythmbox.

Can anyone suggest a way to debug this problem? I am a professional programmer so I can carry out advanced diagnostics as long as someone points me in the right direction. I'm not familiar with the latest Linux debugging tools. An alsa-info dump is included in the issue mentioned above: https://answers.launchpad.net/ubuntu/+source/grub2/+question/119318
