[lubuntu-users] Audio stuttering/crackling in Lubuntu 18.04

[Felipe M. Vieira]

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:

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,
