Open nautilus the file explorer and check if there is any folder with name "modprobe.d" inside "etc" folder.
so path is /etc/modprobe.d/
This command:
echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/alsa-base.conf
adds: options snd-hda-intel model=generic
on alsa-base.conf file.
If the file doesn't exit, it will be created.
if it exists them the option -a will add a new line "options snd-hda-intel model=generic" at the end of file alsa-base.conf
without -a, it will overwrite everything and there will be only the line "options snd-hda-intel model=generic".

    Well I tried everything xD First created modprobe.d directory (via sudo command from kyrios)...
    then used algent commands...and then the old commands from watpi...no result-so I restarted and this time there is digital HDMI...but there is no sound using either one of them:


    I quick look at pulse audio shows there is still nothing other than digital output available.

          Emperor The screenshot shows that the command succeeded.

          Set auto-mute to disabled (via alsamixer). Then in pavucontrol select Internal Audio as device

              [deleted] auto-mute disabled, but don't know which is internal audio-I can't see such an option.

                  Emperor What output devices do you see on pavucontrol?

                      Emperor You need to set that as analog stereo duplex. Dunno why it says it's unplugged though.

                          [deleted] When I do that it's still the same...it's probably unplugged because it doesn't recognize it/detect it.

                              Emperor Does it work on another operating system?

                              Try echo "options snd-hda-intel model=auto" | sudo tee /etc/modprobe.d/alsa-base.conf

                                  [deleted] Wow...now the combination of using analog stereo duplex and the command got the sound working 😀
                                  But from time to time it gets back to digital...also the front jack is just not working...I had to connect the jack directly to the motherboard outputs...on the 1st only left speaker works..on the 3rd only the right works and on the 2nd both of them work! But they work in many modes like 5.1 or 7.1 or just analog stereo...not sure which one to use...also the sound from both speakers is a little strange(maybe just that I used only the right one thinking the left one is broken).
                                  But now when they work I lost my sound on W10 xD
                                  Got it to work for a little but it was strange as in Solus and there was only music-the voice of the speaker is so low that it's very hard to hear it.

                                  Speaker fill option is the difference between sound working bad and not working at all...
                                  Also on the folder on the top right there is an option to dissable front panel jack detection...if it's not used the front jack would not work-so if there is an analog of this in Solus it would make front panel work 🙂

                                      Emperor It's a matter of fiddling with alsamixer and pavucontrol. Some soundcards are tricky. Basically you just need to use the right output device.

                                        So here is a picture of my real panel:

                                        So first the sound worked on the black port...on the left and right of it worked either the left or right port.
                                        The sound of W10 become good the moment I used the port below the black one-it;s kinda green.
                                        So it works on Solus too...the problem is that this jack was once repaired and even the most gentle movement can cause the left speaker to not work or to lower the power of sound...I used tape to partly solve that...
                                        Now the new questions 🙂:
                                        1-The experience is a little buggy so how do I solve that(on hardware level-the cable/jack).
                                        2-As I got my long awaited welcoming sound how do I turn it off 😂
                                        3-From time to time(maybe because of movement) sound changes from analog to digital...also when it's analog and it's working it's shown as unplugged.
                                        4-I got a ton of unnecessary crap programs for managing sound-which ones I can remove and how?

                                          Emperor Yeah, if your speakers are 2.0 or 2.1 you definitely should use the green port.

                                              [deleted] Yes they are 2.1
                                              Inspire T3100 2.1 Channel Computer Speaker System

                                                Now you say the rear jack has been repaired, that is mounted to the motherboard.
                                                Yes the green port is your 2.0/2.1 line out
                                                The front speaker is probably not wired correctly, refer to manual. Also which plug HD Audio/AC'97 is attached to front of case.

                                                It's upsetting if you can't rock and roll. I feel this crazy thread.

                                                a year later

                                                I faced this issue today, then i will share what had solved this for my case:

                                                (Maybe the button names are different. I am using another language in Solus Plasma and trying to translate it to english.)

                                                1. Right click the 'Sound Icon' in the task manager panel.
                                                2. Click on 'Configure Audio Volume'.
                                                3. In 'General Settings', increase the 'Volume Pass' and enable all check boxes.
                                                4. If the step above don't fixed it, in 'Audio Settings', turn off the GPU audio and keep only the audio from bios activated. Then change the bios audio profile to find out one that works.
