I seem to have the same problem, although using suspend instead of hibernate, on my EeePC 900. I'm using the latest Intrepid kernel.
I find that if any sound is playing when I suspend, when I come back from the suspend the sound no longer works. If no sound is playing when I suspend, then everything is fine. When the sound breaks, I see messages like the following in syslog at the time of the resume: Oct 5 06:38:49 eee pulseaudio[5822]: module-alsa-sink.c: Got POLLERR from ALSA I think this is the same thing this bug is describing. If it's different enough that you'd prefer that I open a different bug (or one already exists), let me know. lspci output: 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04) -- No Sound After Hibernation U205-S5067 https://bugs.launchpad.net/bugs/144323 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
