Is this still actual? Does it have anything to do with buffer size? (have you tried changing in preferences?) |
It got a lot worse since I upgraded to Ubuntu 24.04. pipewire 1024 / MS 1024 pw1024_ms1024.mp4pipewire 1024 / MS 2048 pw1024_ms2048.mp4pipewire 1024 / MS 4096 pw1024_ms4096.mp4pipewire 2048 / MS 1024 pw2048_ms1024.mp4pipewire 2048 / MS 2048 pw2048_ms2048.mp4pipewire 2048 / MS 4096 pw2048_ms4096.mp4 |
Did you try 44.1 kHz sample rate? It is a known issue that on many systems you need to set that explicitly. |
Yes it works normally if I set pipewire sample rate to 44100 Hz. For other pipewire users having this problem, I had to run the following commands before starting MS: pw-metadata -n settings 0 clock.allowed-rates '[44100 48000]'
pw-metadata -n settings 0 clock.force-rate 44100 (only 48000 was allowed) |
Closing as buffer size issue is covered in #18701 |
Issue type
General playback bug
Bug description
I recently switched from Fedora workstation to Ubuntu 23.10 (on the same laptop).
With default pipewire settings (buffer 1024, samplerate 48000), the playback speed is unsteady, jumping from too slow to too fast, and creating scratchy sound.
If I change pipewire settings to buffer 512, samplerate 48000, then the sound is back to normal.
On Fedora I never had this problem, (but never paid attention to pipewire settings there)
Steps to reproduce
set pipewire settings to
1024 48000
