I thought I had seen a How To, to set up Manjaro for Music Production

[nikgnomic]

If you are using JACK for audio production, see this post for basic realtime configuration
Configuring JACK2 Virtual Audio Routing - #3 by nikgnomic

I also have a BASH script that can help with realtime configuration specific to Manjaro
ManjaroRealtimeConfig.sh · gist.github.com/nik-gnomic
but script may need updating for the final part about CPU governor

@nikgnomic

• Use this command to reconfigure cpupower CPU governor to performance

  sudo sed -i 's/governor='performance'/#governor='powersave'/g' /etc/default/cpupower
  

• Use this command to start and enable cpupower.service

    systemctl enable --now cpupower.service
