AVLinux - Jack si stoppa

dunque ... non ricordando bene quale fosse il problema che avevo sul pc desktop con AVLinux, ho fatto partire la live e con jack ci sono problemi; ho settato (ma ho anche provato altri settaggi) come la distro Ubuntu studio e Jack si stoppa sistematicamente dopo 5 secondi; ho provato a far partire jack da terminale per vedere se ci sono messaggi di errore, ma non ce ne sono.
Dai messaggi di Jack appare questo

Qualcuno di voi ha idea su come risolvere?

Io non mi fido mai troppo degli ambienti live...secondo me avresti bisogno di installarla, fare tutti gli aggiornamenti del caso (è passato un po' di tempo dal rilascio della versione stabile) e provare a vedere come va a quel punto.
Tutto questo ovviamente se hai modo di farti una partizioncina in più sul pc.

... seguirò il tuo consiglio!! Chissò mai che risolvo?
