You are using a very old version of Sonic Pi (around 2020). The current version which runs happily on Debian Bookworm is version 4.5.1 Why don't you give that a try. Note the internals fo Sonic Pi have changed significantly since version 3.2.2 It now expects to operate under pipewire which seems to be the way that most linuxc are going.
I run arm based virtual debian bookworm on my mac with version 4.5.1

Sry for the delay. You were righr. I am on v4.5.1 now on Debian GNU/Linux trixie/sid. Works like a charm. Thank you!
