So I can't check if this model does sound over HDMI.
But don't plug in any speaker, headphone or 3.5mm RCA to the Audio In if you want to pipe audio over HDMI. That's one way to disable audio over HDMI on some machines.
Again, if you posted the model number and I missed it, sorry.
I know there is a similar thread about this problem, but we've tried everything suggested to no avail.
We're trying to connect an Acer laptop running Windows 7 to a Samsung Plasma.
We're read the plasma manual and it told us we needed HDMI and a 3.5mm RCA to the Audio In. I'm confident we have all the plugs in the right spot.
I tried to follow their directions on
Both the parts are not helpful.
The bottom portion is called
"Follow these steps to change the audio output settings for the HDMI option."
We make it all the way to step 5, however no HDMI sound option is available.
Acer would like me to pay for technical support or they said our driver may not support the sound part.
The computer has an HDMI output, how can this not be working for us.
