I have an issue using the Apple Thunderbolt Display. I have a Dell XPS laptop with Windows 8 where I connect to the display over Thunderbolt, but every time I try to listen to some music or video, the sound comes from the screen, not from my laptop, even if I plug headphones into the laptop. How can I solve this problem? I want to work using my laptop and the screen but I want to redirect the sound to my headphones. Is this possible?
In Windows, you can typically choose a different output-source using this approach:
For quick access to this, you can download this application.
Applicable to OS X users:
This can also be done from System Prefrences -> Sound and the tab Output.
For those seeing this in OS X instead of Windows, there is a separate sound output selection box for "Sound Effects". Make sure to select Headphones.
