I'm hearing the same problem on a Sony Vaio VGN-FE41Z. I read where you say "Unloading/reloading the snd-hda-intel module makes the soundcard work again correctly". I've been unable to do that because the module is always in-use although I don't know by what:
$ sudo modprobe -r snd-hda-intel FATAL: Module snd_hda_intel is in use. -- snd-hda-intel: distorted sound after resume, until the module is reloaded https://bugs.launchpad.net/bugs/100114 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
