I am on Debian Pulseaudio 2.0-6.1. Up to now never had any issues with sound.
I made some experiments with remote sinks and now it seems pulse it totally messed up.
I have only one sink. When I restart pulseaudio pactl shows the sink as IDLE. As soon as an application tries to output sound the state changes to SUSPENDED and stays that way. "pactl suspend-sink 0 0" does not change the state. I can only get it to IDLE by restarting pulse and the cycle starts again.
After a reboot the problem persists.
