[SOLVED]No volume control after adding new gpu (HDA Intel)

I have recently added a new GPU (AMD Radeon 550) and ever since then the sound from my onboard "HDA Intel" has been working but I have no control over the volume. I get the following error when trying to open alsamixer with the onboard sound card enabled:

cannot load mixer controls: Invalid argument

I do not have pulseaudio installed but I can switch to my USB headset or the HDMI audio on the GPU by changing the index number of default card in my `/etc/asound.conf` which looks like this:

defaults.pcm.card 0
defaults.ctl.card 0

I can open alsamixer just fine and change volume when using my USB headset and it opens without crashing with the HDMI card enabled, but I haven't tested audio with it.

I suspect it is a conflict because they are both trying to load the same driver `snd_hda-intel`

Card info:

cat /proc/asound/cards

 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xf7ffc000 irq 47
 1 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xf7dbc000 irq 49
 2 [Headset        ]: USB-Audio - Logitech USB Headset
                      Logitech Logitech USB Headset at usb-0000:00:1a.1-1, full speed

I have tried using index for modprobe:

cat /etc/modprobe.d/modprobe.conf

options snd-hda-intel index=0,1 
options snd-usb-audio index=2

That didn't fix the problem unfortunately.

When I run `alsa-info.sh` i get the following errors:

alsactl: get_control:256: Cannot read control '2,0,0,Beep Playback Switch,0': Invalid argument
cat: /tmp/alsa-info.VT5LoTENCS/alsactl.tmp: No such file or directory

Here is the pastebin link to the alsa-info output

I've been putting up with it for a few days now and not sure how to continue. Any pointers of where to look next would be appreciated.

That particular error is as far as I know a kernel bug in 5.6.2 that got fixed in the meantime, update your system.

Thanks  V1del. You are right, the update fixed it. I realize I broke rule number 1 here. I did a bunch of toubleshooting a few days ago but didn't get round to posting my question until yesterday and forgot to update in between times.
