Sending Minecraft audio to different output device?

When I play Minecraft, I sometimes connect my TV and play a video (a TV show or a YouTube video) and I set the default output device to the TV speakers, but I don't want Minecraft audio to merge with that. I would rather have it come out of the PC speakers.

Is there a way to change the output device for just the one program or to change the output device with Java?

Solution 1:

Load/Change a Resource Pack in-game and for some reason, it causes Minecraft to switch to the default audio output!

Let me know If it works for you.

Solution 2:

The fastest and easiest way to deal with this (until Mojang gets around to fixing the bug, assuming they ever do), is to simply press F3+T. It doesn't require quitting Minecraft or even rooting through the menus (though it will still take a few moments to reload the assets).
