Is an Audio In OLED oscilloscope possible?

If anyone’s still here checking this out, I’m still having problems with my potentiometers with the Daisy Seed and I’m still interested in hearing any ideas for potential solutions

Potentiometers ground issue(?) when audio out socket isn't used

I made this oscilloscope device using the Daisy Seed. There’s a thread about its development here (click through to see code): All that’s on it is audio in and out sockets, an OLED screen, and two potentiometers for adjusting the horizontal and vertical scale of the oscilloscope. The audio I/O is just meant to be a bypass, but I also intended for the device to be used with input only. However, when the output socket is not being used the potentiometers behave in a manner consistent with ground…
