I suspect the latter. We communicate with rtkit via D-Bus, and I would guess that rtkit-daemon is not responding to our MakeThreadHighPriority() method calls. The calls time out eventually, which is why we don't get stuck permanently. The timeout for D-Bus method calls is 30 seconds if I recall correctly, but in case of failure, we retry several times, so the delay grows much bigger. You need to debug rtkit to figure out why it doesn't respond. Multiple pulseaudio instances can be explained by the fact that multiple applications try to use pulseaudio, and each of them autospawns a new instance. The spawned instances would otherwise be short-lived, but they get stuck in the same place as the first instance. Once the first instance gets past the hang, the extra instances should die eventually.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
