Although I guess this issue belongs to my audio interface's behavior, I hope someone can help me.
AF 2.2.1 sound is killed. As Asio Outputs I can select out of 8 Outputs, which belong to my Konnekt 24D Audio-Interface. For curiosity the names are not shown correctly, they are only shown by number. I can play a sound as long as the asio prereferences in AF are opened. Closing the window and going back to the main view, the sound hangs or is killed. I tried different buffers etc... no change.
I could live with that but the demo version of AF works well. The VST Plugin of AF works fine for me.
Any clue?
