Am mac mini 2009 și am instalat ubuntu 20.04 pe el cu succes, dar placa de sunet este falsă, nu primesc niciun ton. Am căutat mult, dar nu am găsit o soluție care să funcționeze pentru mine. Aș aprecia dacă cineva știe bine, să mă ghideze. Driverul de sunet ar trebui să fie realtk hd audio manager. PC-ul este conectat la HDMI care are cip NVIDIA.

Din anumite motive, pe care încă nu știu, a funcționat după repornire, poate că placa de sunet a pierdut contactul. Pentru mine nu este clar ce a făcut-o să funcționeze, dar am încercat multe lucruri.
