Thanks. Unfortunately I have to report that I noticed that with this change sometimes audio just fails the following way. I play an audio file with MPlayer and suddenly at the beginning of a new title instead of the normal audio only tones as played from a guitar are played. I do not know how to better describe. Anyway quitting MPlayer stops audio entirely, but starting to play audio files again still gives the “guitar” sounds. Playing a song with Totem works though afterward and then MPlayer works also again. It just happens arbitrarily once a week and I cannot reproduce this. I do not see anything in the logs, so I do not know if it is a PulseAudio issue or something else. :( Regarding ALSA I only see the following in `/var/log/messages`. hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj. I do not know how to best proceed. Maybe dequeue this patch? Thanks, Paul [1] patch alsa-hda-intel-add-position_fix-quirk-for-asus-m2v-mx-se.patch added to 2.6.33-stable tree [2] patch alsa-hda-intel-add-position_fix-quirk-for-asus-m2v-mx-se.patch added to 2.6.32-stable tree
