Currently the mute button works correctly but the led is non-functional. I've played through hda-analyzer and found out that it's enabled when you enable gpio3 and click out_dir. Clicking out_dir again and again switches it on and off. There's a mute led stuff in patch_sigmatel, sigmatel_spec has gpio_led and gpio_polarity information but alc_spec doesn't have. How should we hook/patch that information into the codec? I'll try to send the alsa-info output tomorrow. Thanks. Ozan
