I have apro/form 620 electric treadmill starts working then suddenley stops

My Onkyo receiver support all audio formats up to Atmos. I'm running it through HDMI but yet the only option I have on the portal is PCM Stereo (Including expert mode) so everything sounds like, well 2 channel stereo. Every other component I have (including my old Shaw gateway) supports the proper audio formats. My TV upstairs, which has just stereo speakers and is hooked up to the BlueSky box allows me to choose Expert Dolby Digital. Is this a limitation of the Portal or just BlueSky in general. Rather annoying and not much of a so called upgrade.

Most of the time its caused from not lubricating between the treadmill belt and deck. This causes friction and the surfaces wear putting greater stress on the electronics. The treadmill is shutting down to protect the electronics. You should stop using the treadmill AND test the following:
1) Mechanical adjustment &Lubrication:
