Play audio from Docker container

On my MacBook (Sonoma 14.6.1), I've got a Python script that uses [pyaudio](https://people.csail.mit.edu/hubert/pyaudio/) (which uses portaudio) to play audio files through my speaker. The script works just fine. However, for reasons, I'd like to run the script inside of a Docker container (Ubuntu 22.04). When I run my script that way, I get

I'm guessing this has something to do with the container being unable to locate the audio device. Is there an option I can pass to docker run to mount the device? UPDATE: I followed the instructions given in [this SO answer](https://stackoverflow.com/a/50939994/8075540) but still received no sound output. I did, however, see some logs from the pulseaudio daemon:

AVAudioSession_MacOS.mm:2397  <-- setPlayState Server update was required.

I tried playing a .wav file from the container with paplay. The command succeeded (and took the right amount of time for the length of the .wav file) but there was no output. The corresponding pulseaudio logs were
