Subject: [PATCH] ALSA: HDA: Use LPIB Position fix for Intel SCH Poulsbo
Git-commit: 645e903528ca6cd510f9ac71a6a23de1a4d931e3
Patch-mainline: 3.2-rc6
References: FATE#313695

Several people with this chipset have reported inconsistent/sloppy
values for position reporting when the DMA position buffer is used,
and that setting position_fix=1 have fixed their problems.
