ALSA: HDA: Set position fix to LPIB for an Atom/Poulsbo based device
commit 1c89fe3b51a2f8068f2f9faa9c48584151416583 upstream.
For the Asus 1101HA, reporting position by reading the DMA position
buffer map seems unstable and often wrong. The reporter says that
position_fix=LPIB works much better (although not 100%, but this is
probably due to other issues).
The controller chip is an Intel Poulsbo 8086:811b (rev 07) controller,
and complete alsa-info is available here:
