ffplay has different default behavior from other players if you want a
stereo downmix, it also (I think) uses SDL which other players don't.

ffplay -ac 2 truehd2.m2ts works OK for me.

ffplay -request_channels 2 should in theory be better with a truehd
source but for some reason it behaves like -ac 2. It works with ffmpeg.
