Bought a CAC-1186 adaptor to replace my old CAC-1170, but just found out it doesn’t passthrough Atmos/TrueHD 7.1 audio to my Onkyo receiver (LPCM and DTS works fine), switched back to my old CAC-1170 and can confirm this one works just fine. Anyone have this issue? Is there any FW update for this adapter?

Please contact [email protected] make sure to mention which Onkyo receiver you use and which Display/Television, and also what the source is, GPU. Be as detailed as possible. Basically explain your whole setup.
