What Audio/MIDI Backend do you use (Menu > Window > Audio/MIDI Setup) and what settings? |
|
|
Jack/Pipewire with 1024 samples. In fact I have feeling that these clitches are coming when changing view in UI. F.e. Edit / mix window or changing to different app - like mixer application. |

These look like dropouts of a period-size. I assume you Ubuntu Studio's pipewire, which is known to have issues. Try Ardour's ALSA backend to test this. If the GUI has any effect it is a hint that realtime permissions are not correctly setup, and the GUI/graphics card can override audio/USB priority. Ardour/ALSA will also show a warning in Window > Log "cannot acquire realtime permissions." if that is the case. |

No logs about realtime permissions. But this comes. [INFO]: Cannot set I/O Priority for disk read/write thread. Partition where I'm writing to is NTFS, cause it's shared drive with windows. Another thing is when using Jack/Pipewire playback can make clitches too when changing view in GUI - when using Alsa there are no clitches when doing that. If pipewire is the problem, any experience about reverting back to pulseaudio? |

Pulseaudio is a desktop system, not usable for pro-audio. so that won't help. Also note that "realtime permissions" will only show up in the Log when you use Ardour/ALSA (not JACK/Pipewire). As for the Disk I/O priority.. try Ardour Preferences > Performance. set i/O Thread count to 1, and scheduling policy to "No priority". Other than that... The is likely caused by your system's setup, not Ardour specifically. Maybe the https://github.com/autostatic/rtcqs quick-config scan can help. |
