No sound when I playon Sibelius 8.5.1

[apollon69]

Hi! I have been working with Sibelius 8.5 and VEP server for some years now and have use the same setup.
But today it is no sound when I play the score in Sibelius.

I set up Sibelius as this:
Active devices -> Vienna ensemble Pro (AU) / VE Choir (Sound set)
Manual sound set -> VE Choir 4 midi chanels -> 1. Choir soprano, 2. Choir alto, 3. Choir tenor, 4. Choir bass

In the Mixer (Sibelius) I open the VE Pro and conect it to my server instance called choir.
In VE Pro I have the instance setup like the attached jpg-file. 

If I turn to Sibelius soundset the score plays with sound, but not with Vienna soundset. 

What do I wrong? it works for some day ago and I haven't changed anything.

If you haven't changed your settings at all, then, it really is unlikely to be those settings.

One thing I have found necessary is to launch my VE components (VEP6 and Mir Pro) before Sibelius or one of its score files. Worth trying?

Hello Ketil!

It can have different reasons, why you don't get a sound.
Do you get a sound when you click on the keys of the virtual keyboard?
Are the Vienna Choir VI presets for Sibelius loaded in the Vienna Instruments?
