Audio and snd-hda-intel

Partendo da questa pagina wiki ho sistemato l’audio del mio PC.

bash-4.2$ lsmod | grep snd

La soluzione è stata creare il file con i giusti indici

nano /etc/modprobe.d/snd-hda-intel.conf
#options snd-hda-intel model=auto
options snd-hda-intel model=intel-alc889a index=0
options snd-usb-audio index=4
/etc/modprobe.d/snd-hda-intel.conf lines 1-3/3 (END)
