From 447ee6a7cbbfb5ae7ab8f9b8b058b4a04fe398bf Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 4 May 2011 18:28:50 +0200 Subject: ALSA: hda - Use position_fix=3 as default for AMD chipsets AMD chipsets often behave pretty badly regarding the DMA position reporting. It results in the bad quality audio recording. Using position_fix=3 works well in general for them, so let's enable it as default for AMD.
