Hi,

Attached is a patch against sound-2.6 (applicable to both 2.6.32.11 and 2.6.33.2) that adds the original reporter's SSID for a quirk entry, allowing for reliably audible sound.

Are you sure that this quirk really changes anything? I checked with hda-emu, but didn't see any difference. thanks, Takashi

BugLink: https://launchpad.net/bugs/554488

The OR has verified that this model quirk is necessary for sound to be audible reliably within both a live CD and an HD install.
