Hello everyone. I was able to get the OCTO card working (in some ways) on my Raspberry Pi 4B after reverting to Raspbian Buster (version from 2/5/2020), and following the manual installation instructions except for the part where you update the Linux Kernel. However it still is having trouble with PureData. When I send an input to an output, the audio passes through un-distorted... But when I insert any objects into the signal chain (even just a [*~ 0.5] volume reduction), everything gets garbled, almost like a bitcrush style distortion. It almost seems like what passes thru is some sort of weird multiplexed version of the audio or something.

Does anyone know what might be wrong? 
 
Thanks,
Ryan Stanley
