Salve,

ho in stallato Ardour ma Jack non funziona.
Ho provato configurarlo direttamente ma mi da questo errore:

ehm... leggere l'output?

hai settato jack per lavorare in realtime, ma il sistema non lo consente.

qui hai 2 strade percorribili:

deselezioni realtime, oppure:

JACK is running in realtime mode, but you are not allowed to use realtime scheduling.

e magari kernel a bassa latenza.

Ciao!

Intanto grazie mille!
ho fatto la modifica come mi hai consigliato, ma niente. Ho tolto l'opzione realtime e funziona. Ma il realtime mi serve per registrare? Grazie!

P.S. ho messo linux-rt  ;D
