Incompatible with pyaudio? about rpi_ws281x HOT 3 CLOSED

That's correct. The Pi only has a single PWM hardware module. The audio
device uses the PWM, as does this library. If you need audio, you'll
probably want to use a USB audio device instead.

So I've encountered a strange issue with my lights while using the pyaudio
module. Using this module in any script on the pi seems to cause the lights
to behave erratically. Running a script with just:

import pyaudio
p = pyaudio.PyAudio()

and then running the strandtest.py will cause the lights to blink rapidly
on and off in a series of random colours. This persists until the pi is
rebooted.

Will do, Thanks.

I know this issue is closed but is there a way to use PCM peripheral instead of PWM to avoid audio conflict ?
As I understand ServoBlaster does it so controlling servo is possible with audio output.
