Buzzy Sound-MSI B450 Mortar Ubuntu 18.04












0















suddenly my sound starts to be buzzy (I've checked my speakers they're OK.), my sound card is a Realtek ALC892. I've also tried the front panel and it's the same. I am using Ubuntu 18.04 and since now everυthing was working fine. Any Ideas? When I restart my pc it fixed but after a few minutes again the same problem.



The only easy solution I found is to unload and load ALSA sound driver with this command :



pulseaudio -k && sudo alsa force-reload


Is a problem that will be fixed with update? or it depends on motherboard's oem?

          Check this solution from ArchWiki. It worked for me on a MSI B450M Bazooka with Fedora 29 when I was listening to music while working and suddenly sound got garbled. This distro uses Pulse Audio, so I just needed to kill and restart the sound server.



          pulseaudio -k
          pulseaudio --start


          The problem may come from the newer implementation of Pulseaudio server, which "uses timer-based audio scheduling instead of the traditional, interrupt-driven approach". There's an option to change this behavior permanently editing /etc/pulse/default.pa file, and changing the line



          load-module module-udev-detect


          to



          load-module module-udev-detect tsched=0
