Sound disappeared from HDMI. MSI message in dmesg.

I use a laptop with slim/xmonad and frequently plug it into my TV and found this to automate the process off setting sound and picture when i plug it in.
Tested it out and seemed to work fine, and now 2 days later, I get no sound from HDMI. PC speaker and headphones work fine and with other PC sound works over HDMI.

I checked and it does change asound.conf when I insert HDMI cable. I don't use a .asoundrc.conf for this user.

/etc/asound.conf
...
     pcm "hw:0,3"
...

But I still get no sound from system or with:

speaker-test -c 2 -D plughw:0,3

I have checked alsamixer if any channels are muted and also manually restarted alsa with:

systemctl restart alsa-restore

Some info:

I'm not to familiar with how things should look but shouldn't HDA Intel, ALC270 Analog be along in:

aplay -L

Also a curious message in dmesg, I'm not using anything from MSI asfar as I know.

dmesg | grep snd
