It appears it was a systemd config issue, rather than an issue with pulse. In addition to updating /etc/security/limits.conf, I also needed to add the following to the [Service] stanza in my pulseaudio service file: LimitRTPRIO=95 LimitNICE=-19 But I still cannot get realtime (fifo) scheduling to work. I additionally have this in my Service stanza: CPUSchedulingPolicy=fifo And this in /etc/pulse/daemon.conf: realtime-scheduling = yes But still not getting realtime priority: # chrt -p `pgrep pulseaudio` pid 1203's current scheduling policy: SCHED_OTHER pid 1203's current scheduling priority: 0 Thanks!
