E-series port replicator headphone jack doesn't work

[kedmond]

Hey all,
I have a Dell Latitude E6400 attached to a port replicator. I am running Ubuntu 8.0.4.

All features of the port replicator seem to work just fine except for the external headphone jack. It plays sounds and music through both the laptop's internal speakers and my external speakers, which are attached to the dock's headphone jack. The laptop's internal speakers should turn off when the speakers are plugged into the port replicator's jack. The internal speakers turn off, as they should, if I plug in the speaker's to the laptop's headphone jack instead of the one in the port replicator. This feature works just fine on Windows.

I am using ALSA for all of my sound playback. Any help would be appreciated. Thanks!

I am having the same experience with 8.10 as well. The sound jack on the port replicator works (i.e. sound comes out) but it does not disable the speakers on the laptop. I have scoured around for solutions and haven't found anything as of yet. Please post back if you found a solution.
Thanks,
RCB

Yeah, no solution yet. I just crank up the volume on my external speakers. Kinda lame. :-)
