FYI: Audio Crackling Bug with Pipewire 1.4.1 + FluidSynth in Debian Testing/Unstable and Work-Around (bugs.debian.org)

In case anyone is using Debian Testing/Unstable and experiencing audio issues, I thought I'd share this.

Until the bugs get fixed, there are two workarounds:

  1. Uninstall FluidSynth
  2. Add systemctl --user restart pipewire to your session startup; this eliminates the problem.

As I want FluidSynth, I went with the latter.

Ubuntu had a general crackling issue introduced last year, an issue around a buffer size which I fixed by copying

/usr/share/pipewire/pipewire-pulse.conf

To ~/.config/pipewire

Uncomment

pulse.min.quantum = 128/48000

And increase to 512/48000. Restart.

systemctl --user restart wireplumber pipewire pipewire-pulse

Increase buffer until stuttering ends. Note this also introduces delay to audio.

Perhaps your issue is something similar? I wouldn’t blindly make these changes on your end, but maybe it’s something to search up on.

This is what fixed my ubuntu audio stuttering too

Tried that already.

Based on the report, this seems to be an actual bug - it was working fine for everyone before the update and only happens in the presence of FluidSynth.

Ubuntu probably hasn't had this version of PipeWire yet.

My work around is working just fine for now, though.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
