I have a very strange problem: When I play sound files that reside on my laptop, they play through the external speakers that are connected to my docking station. But when I play a Youtube video or there is a web page that plays sound, it will only come through the tiny onboard speakers on the laptop. I've gone through every setting I can find on the computer, without finding anything amiss.
What gives??
Are you using the Dell supplied IDT driver for the sound? If not, that is the first step. I do a lot of support on the Dell user forum and we have found that non-Dell drivers either do not work or do not work correctly.
I see two listings in the E6400 IDT drivers. What looks like a driver and the other looks like a driver update. If you are using the Dell sound driver, install the update and see if that helps. Drivers and Downloads | Dell [United States]
