No Sound when using HDMI cable

#1 Post by chzuck » Mon Sep 23, 2019 12:10 pm

When I use an HDMI cable to watch a movie on my laptop, I need to manually select the audio on the T410s laptop to hear the audio on the TV. Is there some way to make this automatic? Using my T510 for the same purpose does not give me any problem.

Is it the same operating system? The same HD Audio driver?

As best I can tell it is the same driver and both are running the latest Windows 10 Pro. It seems to work fine if I change it manually, just will not auto select when I hook up the HDMI cable.

Do both laptops use the same cable or does each have its own cable?
If the latter, try a cable swap.

The same cable is used for both.
