The memlock limit can be raised via systemd unit, which has been done upstream: https://github.com/MusicPlayerDaemon/MPD/blob/v0.22.x/systemd/system/mpd.service.in#L19-L20 But this change obviously wasn't applied to the Debian package.
Systemd unit file used in the package comes from upstream with a minor patch [0]. Then I'm pretty sure LimitMEMLOCK config is present in bullseye MPD 0.22.6-1. I just made a plain install of bullseye (amd64 VM), here is what I got: $ systemctl cat mpd.service | grep LimitMEM LimitMEMLOCK=64M $ systemctl show mpd.service | grep LimitMEM LimitMEMLOCK=67108864 LimitMEMLOCKSoft=67108864 I did not reproduce the “Failed to initialize io_uring” error either. I confused here, please have a look at /usr/lib/systemd/system/mpd.service, LimitMEMLOCK should be there on a vanilla install. Do you have any fragments in /etc/systemd/system/mpd.service.d that could interfere? Cheers k [0] https://sources.debian.org/src/mpd/0.22.6-1/systemd/system/mpd.service.in/
