How to Fix Audio Problem When Using an HDMI Splitter with a TV and PC

It sounds like the splitter might be causing the PC to only recognize the lowest common audio option. Sometimes, when multiple outputs are detected, Windows defaults to the one it considers primary, which in this case seems to be the PC screen without audio capabilities. Have you tried connecting the HDMI splitter first to see if it resolves the issue? Also, make sure that the PC screen and TV can both support audio over HDMI simultaneously. If not, you might need a different splitter that explicitly supports dual audio outputs.

Typically, HDMI audio issues can occur if the devices aren’t communicating properly. You should check the settings in Windows under Sound. By right-clicking on the speaker icon in the taskbar, you can manage your audio devices. If the TV doesn’t appear while both screens are connected, it’s likely the splitter isn't forwarding audio correctly. Try a different splitter or adjust settings in the BIOS, if you're comfortable doing that.

Using an HDMI splitter is a smart way to avoid constantly switching cables! However, splitters can sometimes be finicky about audio. Since they can confuse the computer about which device is the main one, I'd recommend testing with a powered splitter, which sometimes has better audio handling capabilities. Also, ensuring that both display devices are turned on before booting the PC can help with detection.
