Hi
My laptop fails to stream audio over network to speakers connected to my desktop computer.
Laptop runs Arch + Gnome and desktop runs Arch + KDE Plasma, both fully updated.
Laptop plays audio through its own speakers normally, but when I switch to remote output pulseaudio in verbose mode gives me this output:
I: [pulseaudio] core.c: configured_default_sink: alsa_output.pci-0000_00_1b.0.analog-stereo -> tunnel.Arch-PC.local.alsa_output.pci-0000_00_1b.0.analog-stereo
I: [pulseaudio] core.c: default_sink: alsa_output.pci-0000_00_1b.0.analog-stereo -> tunnel.Arch-PC.local.alsa_output.pci-0000_00_1b.0.analog-stereo
I: [pulseaudio] sink.c: The sink input 25 "strawberry" is moving to tunnel.Arch-PC.local.alsa_output.pci-0000_00_1b.0.analog-stereo due to change of the default sink.
I: [pulseaudio] protocol-native.c: Requested tlength=200,00 ms, minreq=10,00 ms
I: [pulseaudio] module-suspend-on-idle.c: Sink alsa_output.pci-0000_00_1b.0.analog-stereo idle for too long, suspending ...
I: [alsa-sink-CX20757 Analog] alsa-sink.c: Device suspended...So my player continues to play the current track until the end (although its seek bar stops) and then stops instead of playing the next track.
I think the problem is Arch installed on my laptop because another distribution installed on it called neon unstable (based on Ubuntu 20.04) can stream audio over network without any problem. I use pulseaudio on both machines, not pipewire-pulse. Any idea?
Edit:
When remote output is already selected and I start to play another track, verbose mode of pulseaudio says:

This problem is still happening regardless my laptop is connected to wi-fi or wired connection.
I even have reset pulseaudio settings on both desktop and laptop by deleting its configuration files in /home/myusername/.config/pulse and /etc/pulse and then reinstalling pulseaudio package. Currently the ptoblem is intermittent and I have not found the cause yet. Sometimes my laptop streams audio over network for hours without any problem until the problem occurs. Which log(s) should I observe to find the cause of the problem?
I also tried RTP following the instructions available in the wiki, but it is unusable for me because audio is out of sync.

The problem persists on my system after update to pulseaudio 15.
I have created a bug report in pulseaudio bug tracker

I have solved this problem by enabling systemd-timesyncd on my laptop. It was already enabled on my desktop.
