Solved LG TV not playing sound when connected via HDMI cable

[majorbob10]

As the title says, I've tried connecting my TV to my computer with an HDMI cable, and the video part works, but no sound plays. When I checked the list of playback devices, the TV appeared (as shown below), but it apparently cannot play sound.

I don't think I know anything beyond what I've posted, but if anyone could help me out with this, I would appreciate it.

Also, as a side note - I am completely unable to interact with any of these objects - I cannot set something as a default device; there is no response when I do it, and disabling the audio device only works until current sources of sound (like videos) are restarted.

If you highlight the LG TV you should​ be able to set it as default. If not, it sounds lik a permission issue (like non-admin account).

Highlight the LG TV, right click, and then select "make default".
