On my MacBook (Sonoma 14.6.1), I’ve received a Python script that makes use of pyaudio (which makes use of portaudio) to play audio information by way of my speaker. The script works simply superb. Nevertheless, for causes, I would wish to run the script inside a Docker container (Ubuntu 22.04). Once I run my script that method, I get

I am guessing this has one thing to do with the container being unable to find the audio system. Is there an possibility I can cross to docker run to mount the system?
