OS, apps and hardware info
Linux local 5.0.0-23-lowlatency #24-Ubuntu SMP PREEMPT Mon Jul 29 16:17:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux jackdmp version 1.9.12 tmpdir /dev/shm protocol 8 Bitwig-studio version 3.0.1 USB2 Audio interface Tascam US16x02
Is possible run audio application with max priority for this application? For best performance and lowest latency without cruckling/buffer problem for audio application.
Ubuntu studio 19.04,
upgrade, install DAW
Bitwig studio 3.0.1, then install
indicator-cpufreq (for changing my cpu to best performance).
Then I ran
jackd in this configuration.
/usr/bin/jackd -dalsa -dhw:US16x08 -r44000 -p128 -n2
I select in
Performance (for best performance), then checked via
lscpu it is working.
Model name: Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz CPU MHz: 3455.159 CPU max MHz: 3500,0000 CPU min MHz: 400,0000 NUMA node0 CPU(s): 0-3
Then I ran Bitwig studio. I tried do load some my older project.
When play the music in DAW, there are some crackling during the playing, and when I do something in DAW during playing (for example zooming or moving only), crackling is even worst.
Jackd log shows me many
I swear I had same configuration before reinstall OS and it was OK for this configuration, no crackling at all during playing even when working in DAW during playing or recording.
I tried install older versions of
Ubuntu studio, no effect, crackling still present, same.
Why is now crackling due playing in DAW? Applet
indicator-cpufreq changed to best performance, but seems not for DAW, no effect for
CPU load in DAW when I selecting between
lscpu shows me different
What is the magic? Before I reinstalled OS, everything works fine. I found something about
nice utility. Is it what I need to setup?
Thank you very much for any information.
