No Sound on HDMI Out - zpfriem - 02-10-2018
I am not getting sound from HDMI. I changed the setting in the retro pie menu, but no audio, still get audio just fine through the internal speaker when connected to HDMI while it is set to headphones. Does the hardware support audio over HDMI? If so, how can I enable it.
Thanks,
Zach

See /boot/config.txt (looks like https://github.com/TheFlav/Freeplay-Support/blob/master/config.txt)
Change
hdmi_drive=1 #Normal DVI mode (No sound) (2 for HDMI with sound)
To
#hdmi_drive=1 #Normal DVI mode (No sound) (2 for HDMI with sound)

I believe you mean change the integer to “2” instead of “1”? I am new to Linux/raspberry pi, do you have a recommendation for accessing the file system on a Mac or Win10 system? Thanks!

Yes. If you put the SD card into your Windows or Mac, it should to mount it as a drive called boot.
In that drive there should be a file called config.txt
You are correct that you could just change that integer, but I am pretty sure that commenting out the entire line will do the same thing.

Thanks for your advice I will try this and report back.

By the way, I think you still may have to change the line in RetroPie after you make that config.txt change.
The reason the config.txt file is like that is because some monitors (that don't do audio) won't run any video when set to '2', so '1' is more compatible with more screens.
