Hello,

I have to report a problem about my GT725 laptop. I use the model : targa-dig. Connect a headphone to my laptop doesn't mute integrated speakers. I can do it manually by muting channels (Center, LFE) to have the sound only on my headphones.

I use the alsa-driver (alsa-driver-20100211) from Takashi Iwai. I have the same symptomes that the stock kernel (from Archlinux).

PS: and the microphone doesn't seem to work.

See my alsa-info on attached file.
