New Install of Zorin 18
Sound works perfectly using headphone socket
However HDMI sound keeps changing from working perfectly, so sounding slightly distorted, to terribly distorted.
Flipping PC back to a MS windows H/D and the sound works perfectly (so its definitely Zorin)

Welcome to the Forum!
Are Secure Boot and Fast Boot in BIOS disabled? Is Fast Start-Up in windows disabled?
You could try it with adding a GRUB Value:
Open the Terminal and type sudo nano /etc/default/grub and in the opening Overview look for the white Textblock:
On the Line GRUB_CMDLINE_LINUX_DEFAULT You add this: snd_hda_intel.dmic_detect=0
So, the Line should look like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"
Then press ctrl+o to save the change, Enter to confirm and ctrl+x to exit. Back in the normal Terminal Overview, type sudo update-grub to make the Changes affect. Don't forget that! Without it, it will not work.
Sadly non of this worked. (btw your original command had a typo "ECT" instread of "etc"
Anyway, tried changing the bios
Tried updating the Grub (and yes i did the update + reboot)
Still the same.
Can I add that the Grub thing seems to (google search) be fix for no sound. I have sound, its just heavily distorted!
Can I also add that at the orginal install, the sound was bad... I thought drivers. So I updated everything in software that I could... and the sound started working fine. Another reboot later and its distorted again.
Thanks, I corrected that.
And I thought tht adding it would help for the Driver.
Do You remeber what was updated?
Have you done any more reboots since then? Sometimes a couple of reboots or being off overnight has healing properties.
In my experience Sound issues on linux are sometimes illogical and some magic is required to stumble on a solution that holds firm.
If you played with alsamixer and find a working Sound setup using that tool, do make sure you save the settings using:
sudo alsactl store
Hi, Thanks for all the suggestions. I have tried a reboot as well as many other things (inc all the suggestions). Sadly none of them worked. I Also have no idea what was installed that made it work for a short while, and don't undersatnd why it stopped working again. Sadly I will have to back out back to Windows as I can't devote any more time to try and fit this!
