Unfortunately, it's is a hardware issue. Receiver's input mapping problem. Cause some *domestic* audio amplifiers like mine =) take whatever is on channel 3 on HDMI and sends it to the sub.
So, it’s up to the user to ensure that they have the material that is intended to be heard through the subwoofer is on channel 3 of their software.
Solution
I need to map the channels differently on their output from Resolve.
This can be done in the track mixer or by switching the audio on channels 3 and 4. Sounds not bad, but before render SMTPE standard file i need double check audio mapping.
