Bruno, which version of Pd is available on Ubuntu via the apt package
manager? On Debian it is

 $ apt --all-versions list puredata
 Listing... Done
 puredata/bullseye-backports,bullseye-backports,now 0.52.1+ds0-1~bpo11+1 all [installed]
 puredata/stable,stable 0.51.4-1 all
 puredata/oldstable,oldstable 0.49.0-3 all

Any reason you want to compile it yourself?

Does it work when you specify
 $ pd -nosound
?
Does it work with a different audio driver architecture, eg. alsa?

Does a pd (any version) installed via apt work?

and so on and so forth... ;)

best, P
