Play Mode Sound Change

Ever since the 1.1 update I have been unable to easily change the sound for instruments. (I generally prefer the clarinet sound in the place of nearly all sustained instrument sounds.) I used to be able to search the available sounds using the Halion Sonic SE window, but now no results show when I enter a search term (see attached image). I suspect there is something going on with the indexing, or the program doesn’t know where to look for the sounds.

There is another thread on this (IIRC) that tells you to delete one of your audio files, which will then be recreated when you reopen Dorico. Check

Thank you!
