[2021] Wireless Headset (Logitech G533) No sound only in Siege

Hello,

haven't played Siege for a while and downloaded a new Update - got a new wireless headset (Logitech G533)

Very odd but I got no sound only from Siege - tried all the sound problem articles on Ubisoft Help already. Searched the www and reddit but no joy

Yes, they are set to default and all other applications are fine, youtube, spotify, Battlefield 2042 everywhere sound but only in Siege no sound - when I plug in my almost broken old headphones via cable I hear sound in-game.

Any helpful tips much appreciated
