'pacmd suspend-sink 0 false' gives Failed to parse suspend switch and the output is still suspended But starting something playing and listing sinks shows the state RUNNING. > You can also try hitting the mute button twice in pavucontrol to see if > it is another occurrence of the infamous "undetected mute on startup bug." Aha! That got it. After that the state went to IDLE and now I can hear audio. While audio is playing it goes to RUNNING and then back to IDLE, then back to SUSPENDED when I close pavucontrol. So looks like this is the cause. Can I help with debugging? Mark > > > I have a suspicion that it might be due to the slow bootup and > > perhaps something to do with suspend on idle.
