|Did you update your Hardware Profiles for Docked & Undocked?|
Right Click My computer, click properties, click on the Hardware Tab, click HardWare Profiles Tab.
I don't recall how to do this . I believe you click on Copy with the Laptop Docked, then Undock it and click Copy. It's supposed to save the current Hardware settings?????
Make sure the Speakers are working before you Copy the Docked Profile. How? I don't know. Try connecting the Speaker after the Laptop is Docked.
Maybe your Users manual will help. My Toshiba gives me no clue how to use this feature.
There is nothing to learn from someone who already agrees with you.
