Hope everyone is well! I am in a bit of a puzzle. My laptop which has been running linux and has had sound for three years now has suddenly gone mute.
After a bit of reading I still am unable to figure out the answer and google is dried up.
The error message i get which I believe everything to be linked to is
dmesg | grep hda
[ 8.878521] snd_hda_intel 0000:00:1b.0: power state changed by ACPI to D0
[ 8.878530] snd_hda_intel 0000:00:1b.0: power state changed by ACPI to D0
[ 8.878551] snd_hda_intel 0000:00:1b.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21

[ 8.903392] hda-intel: no codecs found!
[ 8.903547] snd_hda_intel 0000:00:1b.0: PCI INT A disabled
Now lspci | grep audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
But sudo alsaconf finds the cards but fails to set-up
:: Saving ALSA Levels[BUSY]
/usr/sbin/alsactl: save_state:1519: No soundcards found...[FAIL]
:: Restoring ALSA Levels[BUSY]
/usr/sbin/alsactl: load_state:1625: No soundcards found...[FAIL]
Setting default volumes...
amixer: Mixer attach default error: No such file or directory
Plus alsamixer doesn't work and aplay -l gives --no soundcard--
I really am at the end of the stick any help would be greatly appreciated. Thanks!
