NVIDIA GEForce 210 HDMI output does not sound on LG tv.

Solution
Hello... Yes... 1) check your Control panel-Device manager-Sound, and see if a NVIDIA High Definition Audio hardware driver is installed for it.
2) check Control panel-Sound and see if you have the NVIDIA High Definition Audio enabled as a sound output.

Or... as mentioned above... see if you need to connect your MB sound chip to the Video card.
Whats the make and model of the card? Some 210s had a built in audio device others required a spdif cable from the motherboard for audio over HDMI. You can also look in you playback device and see if you have an Nvidia high definition audio device available.
