yes I have alsa-utils installed, none of the options in alsamixer enables the mic to work.
Solus doesn't detect laptop internal mic
do you see it?

Wow thats a lot of stuff 
Un-mute the S/PDIF Highlight it and press "M" it should change to 00 just like S/PDIF 1 I would also un-mute the headphon just incase its not identified correctly
then go to your sound settings and select the various inputs that should be available in your sound settings.
Also Info here:
https://thesofproject.github.io/latest/getting_started/intel_debug/suggestions.html
I un-muted the S/PDIF and headphon like you said, went into sound settings, inputs where still greyed out.

Yes this is exactly what happen to me and I am unsure what config made the mic selectable.
run this in the terminal and check you can capture from both the mic's
arecord -Dhw:0,6 -c2 -r48000 -f S16_LE -d 10 /home/YOURUSERNAME/test-06.wav
arecord -Dhw:0,7 -c2 -r48000 -f S16_LE -d 10 /home/YOURUSERNAME/test-07.wav
You will get a 10 second recording so make some noises 
test-06.wav didn't record anything at all and test-07.wav recorded my voice just fine. why isn't the mic showing up on input settings on budgie and still creating that sound file?

As I said on github I have the following in a pulse audio modprob but since you don't have this I guess you could add the following line to a file in /etc/modprob.d/ I have one file called intel but not sure if I added it or the sof firmware added it
load-module module-alsa-source device=hw:0,7
This is what my /etc/modprob.d/intel file says
# Do not load the 'snd_soc_avs' module on boot.
blacklist snd_soc_avs You can try add both lines or just one line then power OFF and restart between each edit.
PS: Pulse Audio is what I used to make it selectable
bigrammy I see, I tried both and one at a time of those commands and nothing showed up on sound input(greyed out). I was hoping someone had a solution that worked with pipewire. thanks for the help.
Well I am not sure how to do that.
You can read through the documentation while you wait for someone with more knowledge than me regarding pipewire and wireplumber arrives
https://pipewire.pages.freedesktop.org/wireplumber/index.html
I had a quick look but I cant see how to force the hardware hw:0,7 to be used.
Axios I have pavucontrol installed. configuration tab has no option for Analog stereo duplex or Analog stereo-output. The only options are: stereo output + Stereo input, Stereo output, Stereo input(unplugged)(unavailable), Pro Audio, and off.

As I said I think you need this line
load-module module-alsa-source device=hw:0,7
added to a conf file for example /etc/modprobe.d/alsa-base.conf
You can use nano to create and edit it.
sudo nano /etc/modprobe.d/alsa-base.conf
and what Axios has said.
You can always uninstall Pules Audio later if another method is found using wireplumber.
This may also take a couple of reboots to take affect. I tried all things but nothing seemed to work then boom it was their in the pavucontol so I selected it in there as the default and its worked ever since.
I am not sure why our Asus devices seem to have so much trouble with the mic's.

Axios I have 2 configuration profiles and all the various Analog and Digital profiles and the Pro Audio I have no idea how any of this sound stuff actually works it all seems over complicated to me. 
@darkserge I am going to get some sleep now let us know how you get on.
Kinda basic question we are talking internal mic and not a headset?

bigrammy that worked it shows up in sound input in budgie settings but it didn't get rid of that annoying f9 keyboard mute light
