You also need to execute this then as root, see my additions above.
there is two card listed in the folder sound
card0 controlC0 hwC0D0 pcmC0D7p pcmC0D9p
card1 controlC1 pcmC0D3p pcmC0D8p timer
Check in which of the two folders you find “reconfig”, I guess the second. Could also work with the first one.
card0
controlC0 hwC0D0 input5 input7 number pcmC0D7p pcmC0D9p subsystem
device id input6 input8 pcmC0D3p pcmC0D8p power uevent
card 1
controlC1 device id number power subsystem uevent
I would try the command with card0. Remember, you need root rights (sudo su). Afterwards leave it by exit to return to your normal userspace.
sudo su
echo 1 > /sys/class/sound/card0/reconfig
exit
Another question would be if the issues are linked you the kernel you are using. Sometimes older kernel work better for older hardware. Have you tried kernel 4.14 and 4.19?
I am in root but its denying permission
bash: /sys/class/sound/card0/reconfig: Permission denied
no didn’t try older kernel . I will try it and tell you.
This was a recommendation from Arch wiki, don’t know why it’s not working. 
reverted back to
4.19.144-1-MANJARO
but no sound. dummy output only
OK, then let’s try this:
echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/alsa-base.conf
This command should only be executed once as it’s adding a line to /etc/modprobe.d/alsa-base.conf in case it existed already.
Afterwards, reboot and report.
If you continue to get no sound output and still only see the Dummy Output, then you can try to replace model=generic by model=auto in that file, so edit the /etc/modprobe.d/alsa-base.conf file with a text editor (as root) and change that.
alsa-base.conf add only one line
options snd-hda-intel model=generic
i changed this to auto still no sound…
alsa-base.conf had many line when I was using pop os . I think I just created that fill and added that line .
If generic and auto are not working there is a third option which is:
dual-codecs
Please, try this as well.
After changing. reboot.
no sound… still

Add the modprobe option suggested in dmesg to force loading of snd_hda_intel codec
echo 'options snd-intel-dspcfg dsp_driver=1' | sudo tee -a /etc/modprobe.d/alsa-hda.conf
reboot and check sudo dmesg | grep snd
if dmesg is still showing no codecs found! get more ALSA information
sudo alsa-info.sh --upload
and post the response with the link to data uploaded to alsa-project
there was no file alsa-hd.conf . i created it but still no codec found
http://alsa-project.org/db/?f=ec68d094c6cdbccd75841b12505e6d3877fc083b
this is the response of the alsa-info
libkmod: kmod_config_parse: /etc/modprobe.d/alsa-hda.conf line 1: ignoring bad line starting with 'options'
lspci: Unable to load libkmod resources: error -12
libkmod: kmod_config_parse: /etc/modprobe.d/alsa-hda.conf line 1: ignoring bad line starting with 'options'
there was no audio in mangaro when I was using it live as well.
don’t know if this helps.
Is this a problem of system no allowing the user to use the sound card ?
command i suggested was intended to create file /etc/modprobe.d/alsa-hda.conf
with this line of text in the file - options snd-intel-dspcfg dsp_driver=1
did you include quote marks with the text to get the error -
ignoring bad line starting with ‘options’
alsa-info data posted shows modprobe option added
snd_hda_intel: model=dual-codecs
and in dmesg
[ 7.353455] snd_hda_intel 0000:00:1b.0: no codecs found!
After that there is no sound card in kernel and alsamixer
dmesg | grep snd
Returns nothing
need to use sudo with this command
sudo dmesg | grep snd
(simpler version of command I posted before)
If audio device is detected correctly, data should be similar to my onboard audio device, showing snd_hda_codec used for input and output connections
