On an Asus G50Vt laptop, plugging in the headphone jack mutes the internal speakers and the headphone jack too. Unplugging the jack unmutes both. This is a regression introduced between linux 2.6.27 and 2.6.28, and is still present in current alsa git sources. The root cause is that the g50v hooks in the hda-intel/patch_reaktek driver call an automute function for a different model (m51va). This patch has been sitting in the ALSA bug tracker for more than a year. Any chance int can finally be applied? https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4468 https://bugtrack.alsa-project.org/alsa-bug/file_download.php?file_id=2913&type=bug Even with this patch applied, there's still a secondary problem of the master 'mute' toggling both headphone and speaker outputs (I'm still poking around with hda_analyzer to figure out why) but even that's a vast improvement over no sound output at all when something's plugged in.
