Hello everybody
Indeed the QU-24 works only in 48K and jack makes Ardour believe that we are in 44K (thank you Robin).
For my table, I just have to tell Ardour 48K when the session is started and everything is ok (export or restart the session recorded without USB).
Other: by modifying the frequency with QJACKCTL and restart, it does not change anything.
Again, thank you very much
