I make sound on Linux since 2006, and since 10 years I work with it (live concert, theater...). So I need a stable system. I used Ubuntu, Ubuntu Studio, CCRMA, Musix, KX Studio AVLinux and others...
I had to buy a new computer last spring, not because of power or system too old, but it had some hardware weakness (USB port, battery dead, touchpad). I installed AVL-MX21, but the new computer is too new and some hardware was not well recognized (internal soundcard (!) and graphic cards). So I turned back to my favorites: Kubuntu with KX repositories. (not Ubuntu Studio, which never worked good for me).
Everything seems to work, but I have a lot of Xruns (~100 a minute, audible). This happens when Jack and an app are started, even not connected (Bitwig, Ardour). The proc usage is under 10%, and it happens even under 4%, memory is sufficient, all lowlatency settings are done (audio group, rtirq installed and working), and I use the official lowlatency-kernel. I happens with all my soundcards (RME fireface, different other class-compliant devices, all USB). I tried with latency like 64-1024/3 period @ 96K/48K, all the same.
Here is my system:
Code: Select all
Operating System: Kubuntu 22.04
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3
Kernel Version: 5.15.0-47-lowlatency (64-bit)
Graphics Platform: X11
Processors: 8 × 11th Gen Intel® Core™ i7-1185G7 @ 3.00GHz
Memory: 31.1 Gio of RAM
Graphics Processor: Mesa Intel® Xe Graphics
I really need this to be solved, I can't work anymore.
Thank you for your help!!!
