** Description changed: Binary package hint: linux-image-2.6.27-7-generic The distribution is Ubuntu 8.10. Module version is 2.6.27-7.16. The affected laptop is an Acer Aspire 4530-5267. The soundcard uses the Realtek ALC888S codec and has PCI ID 10de:0774. Whenever I hibernate and resume everything works correctly. However, if I try to suspend the hard disk (or its controller) stops working correctly, and the hard-drive becomes inaccessible. That was worked around with the pci=nomsi kernel option. With this option, the system suspends and resumes correctly, except for the sound. The sound appears to suffer from random buffer underruns (it repeats part of a song for a second or so). It happens when I play mp3 songs through pulseaudio or alsa with any application, - with OSS it doesn't happen. + except with mplayer -ao oss option. That's the only way it works. Other + applications like totem or exaile, even when I have OSS selected in + gnome-sound-properties, playback the sound badly. Things I have tried: - Reloading alsa (with force-reload), manually reloading snd-hda-intel, using position_fix, enable_msi, several model types (acer, auto, 3stack, and others) - Restarting X - Disabling pulseaudio - Installing Alsa 1.0.18 (doesn't work at all) and 1.0.18-rc3 (the bug persists). After this, I reinstalled 1.0.17 via synaptic. Nothing short of a restart makes playback through alsa/pulseaudio normal again. I have attached the sound card status before suspend and after suspend, as well as the codec's status.
