Crackling / clipping with Pipewire and Bitwig (MOTU m4)
- PipeWire version (
pipewire --version
): 0.3.53 - Distribution and distribution version (
PRETTY_NAME
from/etc/os-release
): Fedora 36 - Desktop Environment: Gnome
- Kernel version (
uname -r
): 5.18.9
Description of Problem: Since serveral update of Pipewire, I have a sort of clipping (crackling sound) when I use my USB Soundcard (MOTU M4) with Bitwig and Pipewire or pw-jack engine. If I switch to ALSA, It works without issue.
- I have this problem only with my MOTU 4. No issue with my second USB soundcard (Roland Quad Capture) or internal audio interface.
- If I record a track from my M4 with Pipewire or pw-jack engine in Bitwig, the audio that was captured was not affected (no crackling if I switch to Alsa and listen the track)
- I tried with differents buffer size or sample rate and I have the same result.
- I don't have the issue if I play music with other applications.
- I tried with differents versions of Bitwig and the latest (4.3) who manage natively Pipewire directy from the settings.
I captured the output with another soundcard to illustrate the problem. It's the same sample. One is played with ALSA and the second with Pipewire. I use a sample with guitar and distortion because it's more easy to detect.
How Reproducible:
Steps to Reproduce:
- Open a project Bitwig with Alsa. There is no crackling when the track is played.
- Switch to Pipewire engine and crackling appears when the track is played.
- Listen with headphone for better precision.
Actual Results: Crackling when a track is played with Bitwig and Pipewire engine.
Expected Results: No crackling when a track is played with Bitwig and Pipewire engine.
