FM7 Ultimate Edition - NO SOUND in MP Lobby on XBOX ONE!

Good Morning!

1st - game crashed back to dashboard as I downloaded one of the VIP-Cars from the Fast and Furious set.
2nd - tried it multiple times - with wheel and with standard controller - NO SOUND IN MULTIPLAYER lobby - sound in single player, sound with any other game on XBOX ONE
but not in the multiplayer lobby, not even the menue music. Sometimes it occurs you hear a the menue music for 1 second, than silence the whole race - impossible to play
if not hearing the engine!!!

what a mess.
