Hi 3dit0r,

I inserted a 818v3 controller in MConfig between the HD621 and the DSPs and it gives visually a comms connection between the 818 and the HD621. I stored that but nothing has changed.

The MConfig is as follows:

Setup
- System Address = 1
Audio (down column)
- SmartLink/MMHR, None, 2 Ch, No, No, No, Yes, Yes
Sources
- DVD(H1), CD(H5), Game(H6)
Types
- Type 3
Connections
- C = Meridian Comms Input
