Begin with a simple output
Select the computer speakers or television speakers first. A working simple output separates player problems from receiver and HDMI problems.
Check the selected track
Open the disc audio menu and choose a common track. Commentary, descriptive audio, and high-resolution tracks can behave differently.
PCM and bitstream
Use PCM when the computer should decode the audio. Use bitstream only when the receiving device supports the selected format and the complete output path passes it correctly.
Restore the chain gradually
After sound works, reconnect the receiver, soundbar, or secondary HDMI path one device at a time.
