Problem with audio toolbox (matlab + simulink R2019b) - SOLVED

I just installed the audio toolbox (and the DSP toolbox) but no audio blocks appear in the simulink library browser.

I do see the audio toolbox simulink examples,

but, if I try to load them, a "audio toolbox not installed" warning appears.

I have checked in the add-on browser and the toolbox is reported as installed (and also reinstalled the toolbox) but the audio simulink blocks still do not appear.

I am using Matlab r2019b on Ubuntu 16.04 LTS

Ok, SOLVED, my fault, it was the usual local pathdef.m shadowing the global one, I always forget that one should erase (or update) the old pathdef and rebuild it when installing new packages.
