Thinkpad T42 headphone jack

Archived from groups: comp.sys.laptops (More info?)

Hi,

I have a Thinkpad T42 and I'm trying to figure out if there's any way I can
make the headphone jack remain enabled when it is in the docking station.

The headphone jack works fine when it is undocked, but when I dock it, the
headphone jack on the side seems to become disabled and the line out jack on
the docking station becomes enabled. I do not have the docking station
connected to amplified speakers and I would like to continue to use
headphones when the laptop is docked at my desk all day.

Unfortunately, line out is not the same as a headphone jack and the line out
signal level is not sufficient to drive headphones without amplification. So
either I invest in some hardware to amplify the line out or I find some way
of keeping the headphone jack enabled. Is there any setting in the BIOS or
some control panel that will let me do this?

Thanks
