[PD] Raspberry Pi - priority 6 scheduling failed; running at normal priority

[Edwin van der Heide]

Hi Lucas,

Yes, this works for me!

I’ve created the ‘pd-audio’ group with the corresponding settings (rtprio 95 and memlock unlimited) and added the user to the group. The message "priority 6 scheduling failed; running at normal priority” is gone now.

I’m running Bookworm 64bit in a PI 5. What is interesting is that there is already a 95-pipewire.conf file in the directory /etc/security/limits.d with the following contents:

@pipewire - rtprio 95
@pipewire - nice -19
@pipewire - memlock 4194304

I’m supposing that adding the user to the ‘pipewire’ group would also work although the information on the jack audio page you shared explicitly mentions that "Contrary to a lot of misinformation on the web, there is no reason to include a line here that provides enhanced “niceness” control, which is completely irrelevant for realtime scheduling and low latency audio applications.”

Thanks for the help!

Best,

Edwin
