When you are issuing above strace command, audio/video stream should be running.So that is the reason we are grep'ing for $USER variable We have strace the pulseaudio process of the user (not the gdm process).I found 1000 lines of strace output is sufficient to restore the sound. I tried to some basic level debugging, so started doing strace when audio/video is on. Some of the above options worked for some folks and not worked for most. Set nice level of pulseaudio to -20 and allowing real-time priority of pulseaudioĮcho 0 > /sys/module/snd_hda_intel/parameters/power_saveĮcho N > /sys/module/snd_hda_intel/parameters/power_save_controller.Hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x3000 Hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0圆7 Kill Pulse Audio and change /etc/pulse/default.pa.At present I am running 18.04.I have tried all suggestions from web like:
The output of lspci for my system is: Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02) This script will run on boot as the root user and should result in no more crackling, because it will keep your soundcard ON, instead of allowing it to go into powersaving mode. then, enable the service by typing: sudo systemctl enable powersave
Sudo nano /etc/systemd/system/rviceĪuthenticate, then add the following to the file: Įcho 0 | sudo tee sys/module/snd_hda_intel/parameters/power_saveįinally, make the script executable: sudo chmod+x /opt/powersave.sh You can create a systemd (system-daemon) service script that will run at boot.
