Subject[162/289] ALSA: hda: Add Samsung R720 SSID for subwoofer pin fixup
2.6.36-stable review patch.  If anyone has any objections, please let us know.


From: Daniel T Chen <>

commit a0e90acc657990511c83bc69965bfd3c63386d45 upstream.


The original reporter states that the subwoofer does not mute when
inserting headphones. We need an entry for his machine's SSID in the
subwoofer pin fixup list, so add it there (verified using hda_analyzer).
