Hey sorry to hear you are having this problem. Can you send us an email to firstname.lastname@example.org and we can have a look? We try to keep issues separated from discussion threads.
Uff, now I updated the Link. But I can again not make the sound be heard via PC although I selected Sylphyo Link in the Sylphyo Bench. May it have to something to do with the cooperation with the ASIO program? No clue :(
