laptop speakers stay on when headphones plugged in

[BSDKaffee]

Hi I have a Compal IFL90 laptop with a Realtek ALC268 HD codec. Whenever I plug my headphones in, the built-in speakers stay on. I realize that the speakers and headphones are on two different channels and the only thing I have been able to do is manually disable the speakers in the mixer ($ ossmix connector.line-out.play-speaker ON).

The other issue I am having is the speakers are very quiet. I have to max out all of the volume controls to get a resonable listening level. This is especially true when viewing DVDs in mplayer. I had to use the -softvol and -softvol-max 1000 arguments for mplayer to get more gain. I also use amarok with the xine backend. Even with headphones, I have to turn the volume up pretty high.

This is FreeBSD 7.0-BETA2, but I had FreeBSD 6.2 on this computer too and had the same problems.

Here is my ossinfo:

Thanks for any help.
