Pi 4 audio passthrough

1st Official Post

    I'm just curious as too why when you use audio pass through that it only supports AC3/Dolby Digital and DTS. No support for Dolby TrueHD audio or DTS HD audio, or atmos. Is there some limitation or has it not been implemented in a build yet for the pi 4?

    Support for HD audio hasn't been implemented yet, and since general multi-channel audio is working (on par with RPi3) it's a much lower priority than the major video plumbing work that's in progress. I wouldn't expect it for some time yet.
