Hi there, I got the same problem like some other users in this forum but this one is a little different.

When I connect my headphones my speakers wont mute. So I read several threads about the same problem but I have a "small" difference.

aplay -l
Code:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: HDA Generic [HDA Generic]
Subdevices: 0/1
Subdevice #0: subdevice #0
Model = Generic -.-"


Output for head -n 1 /proc/asound/card0/codec*
Code:
Codec: Realtek ID 272
This codec won't appear on the ALSA list needed to edit the alsa-base

Any ideas?? Thanks.
