I was able to successfully restart pulseaudio with pulseaudio -k on my first attempt, and one other time, but I have been unable to reproduce this. It (pulseaudio -k )usually does nothing. As such, adding "pulseaudio -k" to run on on login as a workaround does not work. This started happening after updating from kernel 5.4.0-48 to 5.4.0-52. Rolling back to 48 makes the issue go away.
