Hi everyone, I'm a long time Lubuntu user and I have been facing audio issues from a `dist-upgrade` from 16.04 to 18.04. I have detailed the question there:
From: https://askubuntu.com/questions/1158648/audio-stuttering-crackling-in-ubuntu-18-04 For convenience: * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 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: - <https://unix.stackexchange.com/a/136591> - Changing `default-sample-rate = 42100` → `default-sample-rate = 48000` at `/etc/pulse/daemon.conf`. - Changing `load-module module-udev-detect` → `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. - <https://askubuntu.com/a/1067759>: `pulseaudio -k`. - <https://askubuntu.com/a/1135589>: Add `options snd-hda-intel power_save=0 power_save_controller=N` to `/etc/modprobe.d/alsa-base.conf`. - <https://askubuntu.com/q/1084491>: Quoting: - add <code>options snd-hda-intel position\_fix=1</code> to */etc/modprobe.d/alsa-base.conf* - edit to <code>load-module module-udev-detect tsched=1</code> in */etc/pulse/default.pa* - add <code>resample-method = src-sinc-best-quality</code> in */etc/pulse/daemon.conf* Points to other sources as well. I have also tried: pulseaudio -k && sudo alsa force-reload Reboot. ------------------------------------------------------------------------ Other solutions which I have not tried because there is no such an option for me: - <https://askubuntu.com/a/1092664> ------------------------------------------------------------------------ I have recently upgraded from Lubuntu 16.04 and it worked perfectly. I have a Lubuntu 18.04: $ uname -a Linux abcde 4.15.0-54-generic #58-Ubuntu SMP Mon Jun 24 10:55:24 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * I have spent several hours on this issue... Can you please help me? Best, -- Felipe Martins Vieira I have transitioned to a new pgp key.
