MBox - HK Home theatre not connecting

[mattlomax69]

Hi - so I have a MBOX running Kodi and when connected direct via HDMI direct to my TV (TCL) there is no issues with sound nor vision. However the moment i connect it to a HDMI port in my Harmon Kardon Home Theatre model number AVR151 I have no picture and no sound. Have checked cables - all good - have checked ports (by plugging in my apple TV) and again all good. I want to run my Mbox through my home theatre obviously. My Mbox is Version 6.0.1 and Build details T5X100006

The receiver will only pass 1080p so if the Mbox is set to 4k it won't work through the receiver.
You can set the box to run 1080p or you can connect the Mbox directly to the TV and get the audio from it.
If the Mbox has a digital audio out you can use that to get audio to the receiver. If not you can use an HDMI input selector with audio extraction that supports 4k.
