Hissing Noise with East West in Dorico 5

Hello all. I just bought the EastWest Engine with Noteperformer. During the trial I did not have this issue; but now that I have it fully installed, there is a hissing noise that ensues before and during playback, as seen here. Any ideas?

Thanks

Update - I found the issue. In EastWest there is a ‘hall noise setting’.
