Hi everybody,
 
for a long I time I had JACK working nicely on Windows 10 with Reaper. Other DAW's which are not on the list of supported software worked even fine.
 
Now for some reason I cannot access JACK in Reaper anymore. I can select JACK as an Audiointerface, but no Inputs and outputs are available.
And in JACK Reaper does not appear in the 'Graph'-window.
 
I tried downgrading to an older version of Reaper, trashing preferences, no success.
Reinstalling JACK also didn't help. 
Other DAW's that officially do not support JACK still work fine.
 
I cannot remember to have changed anything apart from updating Reaper
 
Does anyone has an idea? 
 
Thanks a lot, all the best,
 
Christian
