hp tc1100 weird headphone

Hi,
I have a HP TC1100 tablet now with Vista 2. When I plug in a headphone the tablet's internal speaker does not disables itself, therefore both the headphone and the internal speaker make sound simultaneously. This was the behavior of all previous Vista betas, also. This is the only thing prevent me from complete switch to Vista. Anybody have TC1100? What are their experiences? Solution?
Thanks in advance, B.

I found a workaround: first I tried to install the XP driver for de sound card from HP. It failed due to incopatibility. Than I tried to run the setup.exe in compatibility mode (to XP SP2), there was an error message during the setup proces, but after I restarted my computer the problem fixed! When I plug in my headphones the internal speakers mute. Fine 8-) B.
