Update the ATV to tvOS 14.2 and already had done the HomePod pair in the living room which were already in a stereo pair and had previously been used for ATB audio.
I found that on initial update and playing audio that I had a huge stuttering effect come across the audio and parked it thinking I would solve it later.
Coming back to it and waking the ATV I got the prompt to ask if I wanted to use the HomePods for TV audio and answered yes and this problem went away.
Posted in case this posed an initial problem for others or folks that chose a different option to post their experience.
