Sorry you are having problems with this. I have 3.2.2 running on several RPi and it should be working. Do as @nlb suggests check that you have selected Analog Output from right clicking the Speaker Icon. If you still ahve problems then we need to investigate a bit further.
I assume that you are using the binary deb downloaded from sonic-pi.net, or maybe an earlier version from my r.newman.ch site. Perhaps you could let me know which version you have.
Secondly, have you upgraded the Raspberry Pi OS to the latest version? If you have not, you can do
sudo apt update
sudo apt full-upgrade
There IS a problem with using the RaspberryPi 3.1 version of Sonic Pi with analog output, so it is important to have the 3.2.2 version. Also the 3.1 version can leave jackd running, which prevents changes to the audio output path, so you can try

The 3.2.2 deb downloaded from sonic-pi.net is the latest version, and this overwrites the 3.1 version, replacing it, so that this problem should not arise. The first versions of 3.2.2 I did were designed to run alongside version 3.1 and they appear in the Menu as Sonic Pi 3.2.2 If this is the case I would advise uninstalling this using
sudo apt purge sonic-pi-3.2.2
and then downloading and installing the version from sonic-pi.net for which the file name is
This replaces version 3.1 and appears in the menu as
