I am currently having troubles with audio output with Infuse Pro 7 when playing DTS-HD MA 5.1 audio over eARC. The channels are getting mixed up, I get the central speaker coming from the right rear and the rears coming through the sound bar.
This problem does not occur when I switch back to ARC and so far I am only experiencing this issue with Infuse. I have not seen this with Netflix, Plex or Prime.
Here is my current setup with settings:
Apple TV 4K (4th gen)
tvOS 14.7 (18M60)
Infuse Pro 7.0.9 (3759)
Match Content: Range & Frame Rate
Audio Output: Receiver Speakers
Audio Format: Auto, Dolby Atmos On
LG CX 65"
Digital Sound Out: Pass through
HDMI Input Audio Format: Bitstream
Number of channels: 7.1.4
