I talked to the ALSA developers and they kindly figured out that the necessary patch is to add to sound/pci/hda/patch_conexant.c's cxt5045_cfg_tbl array,
SND_PCI_QUIRK(0x1179, 0xff31, "Toshiba P105", CXT5045_LAPTOP_MICSENSE), This presumably means that I somehow messed up my previous attempt to test model=laptop-micsense. I confirmed the fix so I'm guessing they'll push the patch upstream. Mark -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
