For me ^^^ 7.5-#190401 fixed some trouble with Dolby Atmos Audio not working for all movies with my LSPCon PS176 and my Denon X4500H. Now i can go to use just 1x HDMI for Audio and Video through the Denon to the TV with my Coffe Lake i3-8100 on a ASRock B360 Board. Before i had 1x HDMI 1.4 to Denon for Audio and 1x HDMI 2.0 (DP 1.2 + LSPCOn PS176 firmware 7.85) to the LG TV for Video.
Edit:
Sadly not all problems are gone. Now some AC3 tracks won't play. Back to my 2x HDMI config.
