Running on a RaspberryPi Zero using i2s sound.
- I downloaded a random wave I found (CantinaBand60.wav: https://www2.cs.uic.edu/~i101/SoundFiles/).
- Tested it with
aplay CantinaBand60.wav
. It works fine. - Tried it with simpleaudio and I get an error:
ALSA lib pcm.c:8591:(snd_pcm_set_params) Unable to get period size for PLAYBACK: Invalid argument
Exception in thread sound:

I've seen this on other wave's as well, however, some wave's seem to work fine. I don't know what makes the difference.
Happy to provide whatever other details you may require.
