Roshni Pande (r-pandaa) wrote : PCI/internal sound card not detected. sometimes after running many terminal command lines it gets fixed temporarily but once the laptop goes into sleep mode, then the sound doesnt work again. right now even trying all the command lines that I tried earlier also do not work

aplay -l gives out aplay: device_list:268: no soundcards found...
System settings says Dummy output

cat /proc/asound/card0/codec* | grep Codec
gives out:
cat: '/proc/asound/card0/codec*': No such file or directory
