Sound went full volume white noise after update

I didn't update for a few weeks (last update around 20th Dec 2019) and today after updating and reboot my sound went bananas. Whenever it plays it's like 500% volume no matter what I do, just full loudness white noise. When there's no music playing I have perfect silence but playing any sound, even a system alert, blasts the speakers full volume.

Tried to:

  • reboot again
  • restart pulseaudio with --kill and then --start
  • change volume or mute in pa-applet (on the task bar)
  • change volume in pavucontrol
  • mute device or application in pavucontrol (this works but then I have no sound)
  • change volume in alsamixer
  • mute device in alsamixer (works same as with pavucontrol)
  • look for another profile in pavucontrol but I'm using the only one that isn't unplugged (I've always used this one)

Nothing helped so far. My ears bleed.

I used to be on PulseAudio but apparently inxi now reports I'm on ALSA...? (see bottom)

I have a screen with built-in speakers connected via HDMI cable and currently no other sound output (not even headphones, I just moved).

This are relevant bits of ~/.i3/config:

    # Use pactl to adjust volume in PulseAudio.
    set $refresh_i3status killall -SIGUSR1 i3status
    bindsym XF86AudioRaiseVolume exec --no-startup-id pactl set-sink-volume @DEFAULT_SINK@ +10% && $refresh_i3status
    bindsym XF86AudioLowerVolume exec --no-startup-id pactl set-sink-volume @DEFAULT_SINK@ -10% && $refresh_i3status
    bindsym XF86AudioMute exec --no-startup-id pactl set-sink-mute @DEFAULT_SINK@ toggle && $refresh_i3status
    bindsym XF86AudioMicMute exec --no-startup-id pactl set-source-mute @DEFAULT_SOURCE@ toggle && $refresh_i3status

That means End Of Life, not supported anymore.
Switch to a different kernel before anything else.

For whatever reason it didn't switch to the new kernel. I had to

sudo mhwd-kernel -r linux53

and reboot once again. Thank you!
