From 0708cc582f0fe2578eaab722841caf2b4f8cfe37 Mon Sep 17 00:00:00 2001 From: Paul Menzel Date: Mon, 8 Feb 2010 20:42:46 +0100 Subject: [PATCH] ALSA: 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. $ lspci -vvnn | grep -A10 Audio 20:01.0 Audio device [0403]: VIA Technologies, Inc.
