Feature request - update to run on Pipewire with pipewire-jack.
Maybe I'm missing something or maybe it just is not designed to work yet. I found this utility excellent to test whether tweaks to configuration had effect on older systems with JACK.
Hi Gimmeapill
I've done some work on the xruncounter and added some system info fetching, so that it becomes easier to help users when they share there output.
Here it is:
https://gist.github.com/brummer10/f227061e9d3d08709ccb356068ff7420
sample output looks now like this:
************************ SYSTEM ************************
Chassis: desktop
Operating System: Debian GNU/Linux buster/sid
Kernel: Linux 5.0.7-rt4
Architecture: x86-64
CPU: Intel(R) Core(TM) i5-7400 CPU @ 3.00GHz
***************** jackd start parameter ****************
/usr/bin/jackd -P85 -dalsa -dhw:0 -r48000 -p128 -n2 -s -S -Xseq
********************** Pulseaudio **********************
pulse is active
************************* Test *************************
Samplerate is 48000Hz
Buffersize is 128
Buffer/Periods 2
jack running with realtime priority
Xrun 1 at DSP load 99.38% use 2.15ms from 2.67ms jack cycle time
Xrun 2 at DSP load 99.67% use 2.66ms from 2.67ms jack cycle time
in complete 2 Xruns in 9011 cycles
first Xrun happen at DSP load 99.38% in cycle 8982
process takes 2.15ms from total 2.67ms jack cycle time
