just building my first NUC for a home theatre. Just about to look at the audio side of things, tempted to use the toslink output to my speakers. The HDMI output is connected to my projector. If I have the HDMI and toslink both plugged in will the audio still be transmitted via toslink or will it do HMDI only?
I guess this might depend on the OS installed as well, but I am running openelec.
The audio will go through the device that you configure on the operating system.
My recommendation is to visit the Openelec support to get the proper configuration.
