Notes
- These steps worked for me using pipewire and pipewire-pulse as originally installed by the archinstall script and
using the Focusrite Scarlett 2i2 via a usb3.0 slot
Changes
- Install
realtime-privileges and add your user to the realtime group (see the wiki)
- Create
/etc/security/limits.d/99-realtime-privileges.conf
@realtime - rtprio 98
@realtime - memlock 256
@realtime - nice -11
- Create
~/.config/pipewire/pipewire.conf.d/00-focusrite-scarlett-2i2 (see man pipewire)
