Hi Members. I have a Sony TV running through an HDMI cable. I have excellent video but no sound. HDMI shows up in the Realtech audio controllers but I cant find any way to enable it. Thoughts please!

Is the HDMI output from the computer plugged into a Actual HDMI port or some sort of adapter ?

Bit more info will be helpful as well.

Is it connected Via A graphic Card, if so what make/Model, or is it connected Via onboard,( most modern boards have HDMI Output) again if so what motherboard. ?????

Restart the laptop while HDMI is plugged in. See how you go.

My Sony TV sometime does this. The answer is to turn the TV off then on. In my case, this needs to be done via the main switch, not the remote control

Change the default audio device (via control panel) to digital .
If the audio is dolby 5.1 (dvd movie etc) , it may not work anyway .

Restart both the PC & TV when both are connected.
