[Linux] AudioStream: Floating Point Exception Causing Core Dump

[stefets]

I am on Linux and I try the real time live audio capture with two USB sound card

OS: Linux Mint 21.1 x86_64 
Host: 10AY001TCA ThinkCentre M73 
Kernel: 5.15.0-118-generic 
Shell: bash 5.1.16 
CPU: Intel Pentium G3220T (2) @ 2.600GHz
GPU: Intel HD Graphics 
Memory: 2985MiB / 7750MiB 

The script is simple as possible:

from pedalboard import Pedalboard, Chorus
from pedalboard.io import AudioStream

with AudioStream(
  input_device_name="U192k",  # Guitar interface
  output_device_name="SD90"   # Edirol SD-90
) as stream:
  stream.plugins = Pedalboard([Chorus()])
  input("Press enter to stop streaming...")

My card are configured correctly:

$ cat /proc/asound/cards
 2 [U192k          ]: USB-Audio - UMC204HD 192k
                      BEHRINGER UMC204HD 192k at usb-0000:00:14.0-2.2, high speed
 3 [SD90           ]: USB-Audio - SD-90
                      EDIROL SD-90 at usb-0000:00:14.0-1, full speed

As soon as I lauch the script it core dumped.

$ python app.py 
Press enter to stop streaming...Floating point exception (core dumped)

I have located the core dump and open it with coredumpctl gdb and this is the result:

$ coredumpctl gdb 4736
Core was generated by `python app.py'.
Program terminated with signal SIGFPE, Arithmetic exception.

Does anyone have any advice on how to try to fix this problem?
