Plugging in headphones doesn't mute speakers

[Guest]

I have a Toshiba Satellite A200-AH9 and I'm running Kubuntu Gutsy. I've been having this problem since August 2007 and still haven't managed to get it fixed. I'm not new to Linux, but I don't know a whole lot about how the modules work and how sound is handled.

Anyone feel like helping me fix this?

$ uname -r
2.6.22-14-generic

$ cat /proc/asound/card0/codec\#0 | grep Codec
Codec: Realtek ALC861-VD

$ cat /proc/asound/card0/codec\#1 | grep Codec
Codec: Generic 11c1 Si3054

/etc/modprobe.d/alsa-base: http://howardfamily.ca/~scott/modprobe.d_alsa-base

Need any other information?

I managed to get it working on my A200-14D (albeit the volume being just a bit low) by adding the following line at the end of /etc/modprobe.d/alsa-base

 options snd-hda-intel position_fix=1 model=lenovo

In my case I had to mute front and front mic from kmix output tab; moving front slider however still affects sound level; and the headphone switch obviously has to be checked
