I am trying to get audio working on a friend's old Acer Aspire One running a recent installation of Stretch. During boot, the following message appears:
Code: Select all
[ 9.310394] snd_hda_intel 0000:00:1b.0: no codecs found!
The system does not find a sound card, and pavucontrol shows only a virtual card in the list of output devices.
Below, I am posting the output of alsa-info assuming that it contains all necessary info to trace down the problem. Any help is greatly appreciated.
