It's a straight copy of the Monotron schematic, which as far as I know, works fine. Any differences from that would be a bug. The low pass filter is the same as the Raspberry Pi Zero.
Are you happy with the audio circuit as-is or does it need changing?
Audio connectors are wired incorrectly in the 0.6 schematic.
Band-pass audio filter also looks suspect, and should be reviewed.
