The audio is stuttering/crackling whenever played in external speakers/headphone or the laptop's speaker.
I have tried several solutions to no avail, and different combinations of them:
default-sample-rate = 42100→
default-sample-rate = 48000at
load-module module-udev-detect tsched=0.
This has significantly reduced the amount of noise and slowness of the music but it is not perfect.
options snd-hda-intel power_save=0 power_save_controller=Nto
Audio stuttering on 18.04: Quoting:
options snd-hda-intel position_fix=1to /etc/modprobe.d/alsa-base.conf
- edit to
load-module module-udev-detect tsched=1in /etc/pulse/default.pa
resample-method = src-sinc-best-qualityin /etc/pulse/daemon.conf
Points to other sources as well.
I have also tried:
pulseaudio -k && sudo alsa force-reload
Other solutions which I have not tried because there is no such an option for me:
I have recently upgraded from Lubuntu 16.04 and it worked perfectly. I have a Lubuntu 18.04:
