Multichannel PCM support

Hey there,

I can’t seem to find any definitive documentation online anywhere. Is the Pulse Soundbar 2i able to do anything with 5.1 or 7.1 channel PCM audio?

The LG C9 now does multichannel pcm passthrough and my Apple TV 4K is sending all non-Atmos content to the soundbar as 5.1 pcm.

I’d like to know if the soundbar is properly downmixing that or if it’s doing something else. I don’t have any easy way to determine that on my own.

Thanks,

Nick
