Raspberry Pi 4 Model B Audio

When I start under Python 3, I get the following error messages...

Hi.....i think the changes for Pi that are not yet merged into the official kernel release are all very clean and stable. The default kernel is right now 4.14.z, but you can also try out the current 4.18 release kernel together with the Pi changes from.

I would like to find the information on the open-source hardware and software for qBO.  I want to change the voice to a recognizable natural voice.  I would like to amplify it so I can demonstrate it to a group.  Help!

Hi!.

Just finished an Amplifier for Q.bo.
Here it is during its final play test, after going thru a myriad of tests and burn-in. We will announce very soon. 😊

I advise you to read my textbook to implement Q.BO STEM or Q.BO One at the latest version, with which you can also make it play with chat-gpt.
