<div dir="auto">What happens if you start the pulseaudio daemon in the console? Do you get rt scheduling then? I would check that first to see if pulsesudio is configured correctly. If that works you're probably better off asking the question in the systemd list then...</div><div dir="auto"><br></div><div dir="auto">Best regards, Jürgen</div><div dir='auto'><br></div>

<div dir="auto">Hi Jürgen, thank you for the quick reply. But either I'm missing</div>
<div dir="auto">something, or that says to do exactly what I've already done..</div>
<div dir="auto">Realtime scheduling works when run from the commandline using</div>
<div dir="auto">"runuser" (i.e. so I don't run as root). But when launched from</div>
<div dir="auto">systemd, setting the realtime priority fails (setrlimit() operation</div>
<div dir="auto">not permitted).</div>
<div dir="auto"><br></div>
<div dir="auto">Thanks again,</div>
<div dir="auto">Matt</div>
