PROBLEM: using AppleTV, Optical out on Mijia has audio delay/lag.
Hi guys and gals.
I just bought this Mijia 4K projector and am having a weird issue with audio.
AppleTV ->HDMI-> Xiaomi Mijia ->TOSLINK SPDIF -> Receiver. (Denon) . There is a huge audio delay/lag, it's inconsistent but can be between 1/4" to 1/2". In any case, makes movies unwatchable.
If I change the SPDIF output on the PJ to "PCM" the delay goes away, but why would I watch my movies in mere stereo?
I have tested 2 AppleTVs, the prev. generation (1080p max) and a brand new 4K version. They both have the same issue. With any playback media. (iTunes, Netflix, Amazon, PLEX)
The delay doesn't appear when playing media directly on the Mijia, nor does it appear when playing content off my XBoxOne (tested games, game intro videos, and Amazon)
My receiver is set to zero delay.
So it appears the problem is being caused by the projector, but it ONLY happens when using an AppleTV. I've talked to Apple about it, and it's not something they have been aware of, but I logged my case and hopefully they'll look into it. I searched the forums and can't find another mention of this issue, but I guess it's not very common to use the optical out. The only reason I'm using it is that my receiver is a prev. gen that doesn't do 4K passthrough.
Anyone else having issues with AppleTV and optical out? Or is anyone else using it flawlessly?
