Question:

Why am I getting no audio when connecting my computer to my TV using HDMI or DVI cables?

Answer:

This issue occurs due to a false digital audio signal produced by your computer's video card. When your TV detects a digital audio signal through the HDMI cable, it disables the analog audio inputs. Some video cards generate this misleading signal, causing the TV to switch off the analog audio inputs, leading to no sound.

Resolution: To fix this problem, update your video card drivers. Contact your video card manufacturer for assistance.
