After Testing update I have some weird bling sounds when my monitor loses connection

System sounds not-muted, even though I have them set to muted

Disable pcspkr kernel module that creates error beep alerts

sudo rmmod pcspkr

And create a blacklist entry to prevent udev loading it at boot

sudo tee /etc/modprobe.d/nobeep.conf <<< 'blacklist pcspkr'

Archwiki also now suggests disabling another kernel module that might be needed for KDE

sudo rmmod snd_pcsp

sudo tee --append /etc/modprobe.d/nobeep.conf <<< 'blacklist snd_pcsp'
