Why doesn't my code work on the Raspberry Pi?
Hello,
I'm currently programming a voice assistant and everything worked great on my Windows PC, but when I loaded the program onto the Pi and started the program, this error message appeared:
Traceback (most recent call last):
File "/home/grafjulian08/PycharmProjects/voiceAssistant/main.py", line 1164, in <module>

^^^^^^^^^^^^^^^^^^^^^^^^^
AssertionError: Audio source must be entered before adjusting, see documentation for “AudioSource“; are you using “source“ outside of a “with“ statement?
I have a good microphone on my Pi that works, and I've already tweaked the code a lot, but it won't go away. What else could be causing this?
If you want me to show parts of my code, you can say so.
Kind regards

The problem is that you are:
Do you use a graphical surface at the Pi or do you do anything about Shell?
You should look beforehand in the OS whether the microphone is actually detected and, if necessary, check with a simple audio recorder whether it can actually be recorded. A solid “connect” of an external device (in the case the microphone) is often not enough, you have to install/configure it beforehand.
Please also show the code section where you initially select the microphone.
Thank you for your answer!
I’ve looked at the code again and it’s actually because I have installed the wrong Python version on the Pi, as the microphone works (I’ve already done tests) and the drivers etc. are all installed. I program on a graphical surface, so I could easily check everything.
If I still want to send you the code for initializing the microphones, you can tell me that.
Kind regards
Do you realize that you better contact a PI user forum? 😉
But I’m typing that the EInstellations to address the audio interface on which Sinnlos PC is completely different than on PI.
On the PI you usually use ALSA… is that set up and working?
Yes, ALSA is installed. But I found the problem: it was the wrong Python version installed on the Pi. Thanks anyway!
