Yes! You are right.
I had a similar problem many years ago (but not with playback).
I solved that problem by adding a blank audio to the output stream (-f
lavfi -i anullsrc=channel_layout=stereo:sample_rate=48000).
But of course the filter option that mutes audio also will work (-af volume=0).

P.S: In general it is weird that the file without audio is not
playable. It is definitely the player bug.
