Package: pulseaudio Version: 10.0-1+deb9u1 Severity: normal Dear Maintainer,
I upgraded from jessie to stretch and find that the "stable" system is a lot less stable than before, I'll get to systemd eventually, but I had to deal with minor issues like pulseaudio taking about 20 minutes to start, and other problems reported in the logs. Systemctl reports other failures I have to resolve, but pulseaudio is the start. After searching for solutions on the internet, I ran $ pulseaudio -vvvv with this line in the output (among others) core-util.c failed to acquire high-priority scheduling The full message is this : $ pulseaudio -vvvv I: [pulseaudio] main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted I: [pulseaudio] main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) failed: Operation not permitted D: [pulseaudio] core-rtclock.c: Timer slack is set to 50 us.

It looks like a bug in the source code in this line: I: [pulseaudio] main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted I haven't checked to see if this is resolved in later versions of pulseaudio.
