--- Comment #4 from Tanu Kaskinen <tanuk at iki.fi> ---
The latency information is partly provided by the hardware, and the hardware
can only provide that information when it's running. The information can't be
faked. The fake latency would have to include the time that it takes for the
device to be opened if it's suspended, and that time is now knowable.

Imagine playing a video with some silent parts. If PulseAudio stops streaming
to the hardware, then the hardware needs to be opened when the silent part
ends, and that will take some time. That very likely causes glitches in the
video playback.
