It has Intel HDA audio[1] and everything works fine, including the built-in mic. The only think I can't seem to get working is a headset w/mic. I know the HW for dynamic detect works because the mic is detected dynamically under OSX. Is there some setting I need to tweak in order to enable the automatic mic detection? Thanks for any pointers, Kevin [1] $ cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xa0600000 irq 46
