Speaker system: Panasonic SA-PT860 (5.1)
HDMI-HDMI cable You
need to get sound on the speaker system from a computer. Googling, I couldn't figure out what the problem was. At the moment, acoustics are connected to the video card using HDMI.

Answer 1

Most likely, the sound cannot be turned on without a monitor on the back of the HDMI. On the acoustics there is an optical input, on the motherboard there is no output? Judging by the mixer, there is some kind of digital output there. Also, the coaxial output is in the form of a header on the motherboard. In this case, you need to make a wire and buy a Coax > Toslink adapter.
