Unfortunately version 3.2.2 is not suitable to run on Ubuntu 24.04.1 as you have foun. In common with most modern Linux it uses pipewire to handle audio, and version 3.2.2 is setup to use jackd This linux package is produced externally and independently of the Sonic Pi developers, and has not been upgraded. Sonic Pi does not lend itself very well to the creation of a standard debian package, although it does build fairly easily from source. In the past I have produce binary packages to install Sonic Pi on Ubuntu, but unfortunately I only have access to Macs, and thus can only build for arm based cpu on virtual machines.
There is however an altenative flatpak Sonic Pi which will run on 24.04.1 although I have seen a report of difficulties with it on 24.10. You might life to try using that instead. https://flathub.org/apps/net.sonic_pi.SonicPi
