Well, I wrote the parameter to grub.cfg, rebooted, checked sound in console (ok), then logged into grapphical mode, tried vlc sound did not break, started firefox, tried youtube, and sound was broken again. Knowing that it is pulse, is there a way to restart it? cer@Telcontar:~> cat /proc/cmdline BOOT_IMAGE=/vmlinuz-5.3.18-lp152.72-preempt root=UUID=ac173013-18ad-4c4e-921e-fd2ecfb56495 resume=/dev/disk/by-label/nvme-swap splash=verbose verbose snd_hda_intel.snoop=1
