Hey there! I downgraded to WaveLink 1.5.0, and have been trying assigning knobs in the Loupedeck software, with mixed results:

1. It obviously communicates; the 'Input volume (monitor)' knob adjustment results in visual changes in the WaveLink software's slider; and the 'Input volume (stream)' button-press visually toggles the 'click to mute' button in the Wave Link software;

2. ... but plenty of controls have no effect (the 'Input volume (stream)' adjustment doesn't actually move the WaveLink slider at all) unlike the 'monitor' one); nor do any of the output-volume / output-mute controls seem to have any effect.

3. Even though 'Input volume (monitor) functions, the feedback on the Loupedeck's display is incorrect - it just permenantly says "Stream Mix Volume muted", no matter what I press/do, either in the WaveLink software, nor on the Loupedeck.

(I'm a fellow dev, and I have some minor C# experience; let me know if there's any useful debugging steps I can undertake for you. =)
