L'audio sul mio PC funziona senza problemi con Ubuntu 20.04 LTS.
Se installo Debian 10 (GNOME) il mio audio funziona subito dopo il primo riavvio dopo l'installazione, quindi smette di funzionare dopo il primo update / upgrade di apt.
Dato che ho fortemente bisogno di usare Debian 10, potete aiutarmi a capire, per favore?
Grazie.
