Python • Re: Running PyAudio Script On Startup Issue

No. By headless I mean without monitor (and keyboard, and mouse).

No, my pi isn't headless. I have a TV with a keyboard and mouse connected.
BTW, that user's systemd solution didn't work. I doubt that's the best method anyway.

1) What was the issue?
My pi is headless. It works very well there.
Recently I have been facing issues after switching to a compute module...but I guess that's another issue.

Try looking at the journal

Code:

journalctl -u your_service_name.service

and see what went wrong.
Did the service not start on boot? Did the python code not execute?

2) One more thing, pyaudio has gotten old.
I switched to python-sounddevice after facing several problems with it. It does the same thing as pyaudio, and it's also a wrapper around PortAudio. But it has better documentation and is easier to use. You can see if that works for you.
https://pypi.org/project/sounddevice/

3) Most of the error message you are getting from pyaudio is unnecessary warnings. Try suppressing them, then you will be able to see the actual error more clearly. Take a look at this answer.

4) It could be that pyaudio ends up using the wrong audio card, since you have HDMI etc. Try setting the audio card explicitly. In Sounddevice it's done by:

Code:

sounddevice.default.device = audio_device

. You can find the available audio device by running

Code:

arecord -l

in your command line.
