6. Enable HDMI Auto Detection

As the TV is the output device and it is now connected to the PC, you have to do the following steps. Enable the auto-detection of HDMI sound output on your computer sound settings.

    open realtek audio console

7. Check if the HDMI Cable is Faulty

Check the HDMI cable connection at both ends of the connection. The cable may have issues at either end connected to the PC or the TV. Also, sometimes not inserting the cable properly at the input and output ends can cause sound output issues.

Unplug the cable and re-insert it properly on the computer as well as on the TV. If the HDMI audio is not working after reinserting the cable, you may replace the cable. If you have a spare HDMI cable lying around, use that.

8. Tweak the Volume Level of the TV

It may seem like a silly fix, but often within this lies the root of the inaudible HDMI output issue. Check the sound output on the TV as it is the output device. Your TV remote may be faulty, and its volume rockers may not be working.

Try to increase the volume using the buttons present on the TV. Also, check if you have accidentally enabled the Mute option on the TV. If that is the case, unmute the TV, and you should be good to go.
