ALSA: hda - Add position_fix quirk for Biostar mobo
The Biostar mobo seems to give a wrong DMA position, resulting in stuttering or skipping sounds on 2.6.34. Since the commit 7b3a177b0d4f92b3431b8dca777313a07533a710, "ALSA: pcm_lib: fix "something must be really wrong" condition", makes the position check more strictly, the DMA position problem is revealed more clearly now. The fix is to use only LPIB for obtaining the position, i.e. passing position_fix=1. This patch adds a static quirk to achieve it as default.
