Graph component disappears in Sound Design panel

[edwardjarchibald]

The graph part of the 'Sound Design' panel disappears, at some point, after working normally immediately after a clean, new install. Once this happens, no amount of restarting the beocreate2 service, rebooting the Pi etc. will clear up whatever is going on. It doesn't seem to matter how many filters are defined etc.

As a workaround, perhaps there are some settings stored somewhere that I can delete/tweak/reset?

Pi model: Raspberry Pi 4 Model B Rev 1.5
Sound card: DAC2 Pro + DSP add-on Module
HiFiBerryOS version: 20220826
Linux Version: Linux 5.15.56-v7l
DSP Program: DSP add-on version 13

I see the following exception is showing up when this happens:
