Public bug reported:
Binary package hint: pulseaudio
I'm using module-alsa-sink to route pulseaudio through to hardware (for
compatibility with non-pulse-supporting apps) and I've noticed that it
takes a couple of seconds for actions like pause, stop, play, volume-
change etc to have any effect on the sound output.
I used pacmd to list-sinks and discovered a very high [looking] number for my
alsa-sink. Here's the output:
* index: 0
