3.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: David Henningsson <redacted> 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: https://launchpadlibrarian.net/86691768/alsa-info.txt.1TNwyE5Ea7 BugLink: http://bugs.launchpad.net/bugs/825709 Tested-by: Stefano Lodi Signed-off-by: David Henningsson <redacted> Signed-off-by: Takashi Iwai <redacted> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> --- sound/pci/hda/hda_intel.c | 1 + 1 file changed, 1 insertion(+)
