I have installed Debian 12.7 (GNOME 64 bit) on an old Acer laptop that is about 9 years old. Everything seems to work except I have no sound. I have checked that sound is NOT muted by software or keyboard. I have researched to problem and found the following:
aplay command shows no sound card:lspci command output :I also have system messages showing so firmware packages that could not be loaded that seem to be related to sound. Any help in resolving this problem would be greatly appreciated.
aplay command shows no sound card:
Code:
$ aplay -laplay: device_list:274: no soundcards found...
Code:
