Random sound loss after resuming game on XB1 S

This has happened several times & has just happened now : upon turning console on & resuming the game the sound has totally disappeared.
The normal sounds are there on the homepage of the console & elsewhere, just not in the game. I have to quit the game & re-launch it & the sound returns. Very frustrating…
This does not happen during the gameplay, only after turning the console on & resuming the game.
Anyone else experience this?
