Hi,
I have a SER8 8875HS and I have the same issue.
I did all the recommendations from above but still no sound.
Here are the characteristics (in french) :
Nom de l’appareil DESKTOP-6CLV5UO
Processeur AMD Ryzen 7 8845HS w/ Radeon 780M Graphics 3.80 GHz
Mémoire RAM installée 32,0 Go (27,8 Go utilisable)
ID de périphérique 5FAF59B6-B007-4BBA-8FAB-AB70778B9D35
ID de produit 00331-20316-01336-AA919
Type du système Système d’exploitation 64 bits, processeur x64
Should I send the SN Code at the bottom of the machine ?
