As far as I can tell, it made no difference; but I cannot be certain it did nothing, as I haven't been able to get audio working for the past week or so (except for one instance). But correct if I am wrong, but isn't PulseAudio is a sound server with an Alsa (default in Ubuntu) backend, with backend being responsible for detecting and managing hardware?
Anyway: kudos, you gave me the first new thing to try since I begun scouring the web trying to get it to work. I have a couple other symptoms that may or may not help: 1) the times when I got the card to be detected (but not work) during boot, there are now two entries in boot.log instead of one: * Starting System V runlevel compatibility[122G[ OK ] * Starting restore sound card(s') mixer state(s)[122G[ OK ] [...] * Starting deferred execution scheduler[122G[ OK ] * Starting restore sound card(s') mixer state(s)[122G[[31mfail[39;49m] 2) When the card fails to work on boot, there is no entry in /sys/devices/pci0000:00/ for the PCI address of the sound card (0000:00:07.0 in my case, as the attachments above show). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/779983 Title: [Natty] Unreliable detection of snd-hda-intel with Conexant CX20549 codec -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
