I tried your patch. (Sounds great!)
Filter mode knob works as expected and changes the sound.
If you were to start with a totally simple patch - the saw with no filter envelope, 50% cutoff, 50% res - and change the filter mode, do you hear anything on LP, DP, HP? Or is only notch working on all patches?
When you say you get nothing, is it total silence? Can you hear the amp clicking, any of the oscillators?
The mode knob is not not something that firmware should affect - I believe the modes are analog, hardwired to the selector knob.
I think if you've tried everything and only Notch produces sound, you need to get a support ticket started.
