When unpausing, there is a 1 second delay before audio resumes with fifo visualizer

[Fxzzi]

Bug report

Describe the bug

When pausing and then playing music again, there is a small delay before the audio begins to play again. The song is playing in between this time, as I can see the visualizer on ncmpcpp moving before the audio comes back. This happens across two devices, a custom built PC with a Ryzen 5 5600x and my laptop with a Ryzen 5 7530U. Both devices are running pipewire.

Expected Behavior

I expect the audio to resume instantly, like how it does with fifo visualizer disabled. I think some other issues are also related to this, including random popping audio and random cutting out of audio for a second or two.

Actual Behavior

Instead audio only pops back in a second or so after resuming from mpd or ncmpcpp

Possibly related to/duplicate of #1136.

From what I can tell, I experience this issue with visualizer disabled also. In ncmpcpp, holding down p to rapidly pause and unpause does infact skip time in the song. However this is an instant skip, unlike this where its a 1 second delay.
