Had an experience, might help you smart people track down what the problem is:
I've been having this problem for a few days now (even though I upgraded to 10.04 back in early may). Just formatted my / partition and downloaded/burned a 10.04 disc today (7/18) (for a few reasons, this being one of them). Out of the box, sound worked, boot was normal, and I received none of the spurious response errors. Updated everything in update-manager. activated nvidia prop. drivers (starts at 21:21:30 in log). Without rebooting, more updates appeared in update manager, and they were installed. Installed some inconsequential programs and rebooted. Sound still worked. Installed libxine1-ffmpeg gstreamer0.10-plugins-ugly and ubuntu-restricted-extras. Rebooted again and the problem is back in spades! I'm dubious that its the plugins or restricted-extras, so maybe like usual it was just the luck of the draw that let me reboot ok? Attached is tonights portion of dpkg.log (everything since the fresh install). ** Attachment added: "dpkg log since fresh install" http://launchpadlibrarian.net/52144427/dpkg%207-18-10 -- snd-hda-intel: spurious response messages in dmesg - causes crackle https://bugs.launchpad.net/bugs/433189 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
