[Problem]: stops working if paused for a time #1759

Closed tom8347 closed 1 year ago

tom8347 commented 1 year ago

What happened?

I connect to the Airplay device through my linux computer running pipewire with the module that allows airplay connections. I play something and everything seems to be working. If I pause the stream (eg teh spotify app on my computer or whatever) for more than about a second and then try to resume, my desktop tells me that the music is play, but there's no sound. If instead, I initally connect then pause the stream for only a very short time, it resumes with no problems.

It's worth noting that this does not happen if I use pulseaudio instead of pipewire on my desktop computer. Also, as far as I can tell it's not a problem with my iphone.

Since this problem is only seen with the desktop, I'm not totally sure it's actually a problem with shairport, but I wasn't sure where else to look.

Relevant log output

this is the output from shairport-sync -v if I pause/unpause the stream quickly (resumes with no problems).  You can see the bottom few lines (RECORD: Duplicate RECORD ....) correspond to me pausing/unpausing the stream

this is the output if I pause/unpauses the stream with a longer time between pausing and unpausing.  You can see the last few lines which correspond to the pausing/unpausing have changed (the lines with Large negative etc etc are now missing)

System Information.

I'm running shairport, compiled without Airplay 2, on a raspberry pi 3 model B with an ethernet connection. It's outputting to an SMSL SA300 DAC.

My desktop is NixOS with pipewire.

PulseAudio or PipeWire installed?

How did you install Shairport Sync?

Thanks for the report, and for the exemplary diagnostic information.

This looks like (another!) problem with the AirPlay module in the PipeWire system of your Linux machine -- those duplicate RECORD messages shouldn't be happening. They are ignored by Shairport Sync but who knows what is coming after them. I suggest bringing this to the attention of the developers of the PipeWire AirPlay module.

tom8347 commented 1 year ago

Okay, I'll figure out where they live and do that. I'll close this issue for now. Thanks for the quick reply!

mikebrady commented 1 year ago

Thanks. Let me suggest that you check the correspondents on that other problem -- I think one of them might be connected.

mklein9 commented 1 year ago

Might be unrelated but I had a similar issue a few months ago and tracked it down to not having all the required open ports between VLANs, where shairport-sync was running on a device (RPi) on one VLAN but the music player was on a different VLAN. Is it possible your phone, desktop, and shairport-sync may be on different VLANs with a firewall between them?

See https://github.com/mikebrady/shairport-sync/issues/1664.

this is the output if I pause/unpauses the stream with a longer time between pausing and unpausing. You can see the last few lines which correspond to the pausing/unpausing have changed (the lines with Large negative etc etc are now missing)

System Information.

I'm running shairport, compiled without Airplay 2, on a raspberry pi 3 model B with an ethernet connection. It's outputting to an SMSL SA300 DAC.

My desktop is NixOS with pipewire.

Configuration Information.

Display Config Start.
