[PATCH] hda-intel: Add position_fix quirk for ASUS M2V-MX SE.

[PATCH] hda-intel: Add position_fix quirk for ASUS M2V-MX SE.

With PulseAudio and an application accessing an input device like `gnome-volume-manager` both have high CPU load as reported in [1].

Loading `snd-hda-intel` with `position_fix=1` fixes this issue. Therefore add a quirk for ASUS M2V-MX SE.

The only downside is, when now exiting for example MPlayer when it is playing an audio file a high pitched sound is outputted by the speaker.

Applied.  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
