Hello everyone,
I’m a little new to the form and may not be in the right place so be kind and don’t yell to loud… 
“Modiators” Please feel free to move this where it should be…
So Yes I did do a bunch of searching for a bit here and the interweb and did not see anything that might help so I am posting this here if that is ok…
I am having a issue with my HDMI audio not working in the EndeavourOS… I am having the same issue with other OS’s like, MX-19, Linux Mint 19.2, Manjaro-Cinnamon 18.4…
I play alot in VM’s and on real test systems if I like it… That includes EndeavourOS…
Now, Mint 18.3, MX-18, PepperMint 10, Ubuntu 16.04 all work on these Mobos with the HDMI Audio working…
The only thing thats changes it the HDD or the USB stick that I am booting from…
A bit of history been running MX, Mint, Ubuntu, and so on this box with no issues. The sound has work on all versions with the same setup.
My Dell has both HDMI and VGA video out (yes both at the same time)…
Has the standard audio plugs, the green plug being the soundcard. Everything is build on the Motherboard video, usb, network, etc…
Note:
I have 3 Gigabyte Mobos that are the same as My Dell, Video setup, Network, Sound and so on but they have 4 core AMDs and 8 gigs of ram.
However I do not use the onboard soundcard.
I use the HDMI port for my video and audio through my 46" and 32" tv’s. I have the audio piped into my stereo system from there for both computers with optical cable. This setup has work from day one for years…
Now to the ISSUE:
After installing MX-19 or EndeavourOS or Manjaro on a seperate HDD on the Dell system in question, which also has MX-18.3 on its own HDD and everything is working as it should, video and sound and so on…
I am booting from separate HDD’s with my F12 key and choosing what HDD to boot from, MX-18 to other Hdds or USB sticks.
After installing MX-19 or Mint19.2 or EndeavourOS, Manjaro-cinnamon 18.04 the sound does not work at all on the HDMI or the built-in soundcard until I turn on the internal soundcard in the sound/mixer settings.
I don’t use the built-in soundcard, so I had to find a cable to hook it to my stereo to see if there was sound from the onboard soundcard and there was not! So I had to go to the Mixer and there I found that the settings was not set for the soundcard but for the “Digital Stereo Output” which there is not connector for that, so I changed that and got the onboard sound card working.
At first the sound was in slow-motion but then cleared up and worked ok.
Now for the HDMI sound…
All the OS’s reports there being a HDMI Audio Card(s) and it is a AMD and so on, but it reports it as being “HDMI Unplugged” which is not true as I have video…Lol
I have been testing stuff and I find that the kernel (old 4.09 or new 5.3) did not make to much of a differences, I used new ones and old ones… The ALSA drivers on all the OS’s that HDMI work and don’t work are not that different in the Version numbers.
1: ALSA V:k4.19.79-1 for Manjaro 1804 No HDMI sound ??? Maybe!
2: ALSA V:k4.10,0-38-generic Mint 18.2 Has HDMI Sound
3: ALSA V:kv4.18.o-18-generic Peppermint 10 has HDMI Sound
The sound driver: snd_hda_intel is the same on most everything…
As for Plusaudio I have not been able to figure that out… 
The onboard soundcard ALWAYS works no matter what OS is being used, Some have to be turned on in the Mixer and some not…
I borrowed a AMD Radeon HD6450 1GB Graphics Card from a friend that is like the Mobos. (HDMI, DVI) where the Mobos have the VGA too. I have been using it for testing. Kinda neat can have 4 Monitors at once… Digressing…
So Aplay -l reports it them there, shown below, “Card 1” is the onboard and “Card 2” is the add on card…
>> ~/bin : -> aplay -l

Here is all the EndeavourOS board information on the Gigabyte Mobos I have (probably more than needed)… The Dell Mobo’s Infomation is below…

So after 3 days of messing around there was no Joy on the sound issue.
Booting off of USB sticks or HDD installation no sound on the HDMI…
I once again had to fix the onboard sound card issue which was not a issue as I done it before…
Now if I boot into MX-18, Mint 18.3, Peppermint 10 everything is working as it should on the HDMI…
NOT changing anything but OS’s
Booting into EndeavourOS Not so much, for the HDMI sound anyway!
Everything else seems to be ok…
BTW I have the same sound issue booting off of the USB stick for the newer OS’s…
From what I can tell the Kernel version and Sound drivers are newer and might be the issue…
Your thoughts???
I would take a wild guess if it works… 
Here the Information I have on the system Dell with MX-18…
