Hello, like you, I have this problem too. I don’t have this problem on all my wyses in thinos version 9.1.5067 some have no problem. On the other hand, all my wyses in 9.1.1131 do not have the problem, at first I thought it came from the udp audio which was not activated because I already had a similar problem with version 9.1.1131 but That’s not the case here. Did reinstalling the client with the merlin image fix your problems? (namely that my wyses have gone through all versions 9.0 to 9.1.5067 with wms).
