Hi, /help.ubuntu. com/community/ UbuntuStudioPre paration
I got this from: https:/
Real-Time Support
Now you need to set up real-time access for your applications.
All you have to do for this is give your audio group permissions to access the rtprio, nice, and memlock limits. To do this, you just need to run these commands:
sudo su -c 'echo @audio - rtprio 99 >> /etc/security/ limits. conf' limits. conf' limits. conf'
sudo su -c 'echo @audio - memlock 250000 >> /etc/security/
sudo su -c 'echo @audio - nice -10 >> /etc/security/
