I have an alsa-info of a slightly differently machine here: http://launchpadlibrarian.net/49532111/alsa-info-forrest The difference is two outputs (one line, one headphone), and two inputs. > >> Here's my analysis so far: >> >> 1) If there's one internal speaker and one line-out (rather than >> headphone-out), should the internal speaker auto-mute?

Nice, thanks for spotting! I've attached a signed-off commit that un-ignores both 0x1b and 0x1a (the latter one used in the alsa-info link above).
