Playback doesn't start from the beginning when using Pulseaudio

[odiroot]

I have noticed, when running Go-Librespot with Pulsaudio backend, sometimes the song doesn't play from the beginning but from somewhere 1s+ from the start.
Reproduced both inside Podman container and directly on Linux.

How to reproduce:

1. Start Go-Librespot with Pulseaudio backend.
2. Open Spotify on your phone and switch the device to Go-Librespot.
3. Play any song (best some song that is audible from the beginning).
4. The audio will start about 1s (or later) from the beginning.
5. Click on another song to start playing.
6. This song will actually play from the very beginning.
7. Pause the playback, wait a minute or so.
8. Choose another song to play.
9. This one will also start playing from about 1s mark.

In short: "cold start" doesn't start playing from 0:00 but somewhere 1s further. "Warm start" starts playing from 0:00 correctly.
Successfully reproduced on two different computers, running on bare OS as well as within a Podman container.
Additionally I couldn't reproduce this behaviour on ALSA backend, only Pulseaudio.

Environment (one of the two where I hit the issue):

• Spotify on Android for remote control.
• EndeavourOS Linux x86_64 with kernel 6.17.8 for the host machine.
• Pipewire 1.6.1 for the audio setup.
• Go-Librespot v0.7.1 (but also happened on earlier versions).
