Owntone intermittent Airplay to Shairport-sync

kevocl commented 2 years ago

What happened?

Not sure where the issue lies with this one, as it is regarding Owntone (latest docker image from linuxserver.io - forked-daapd) and Shairport-Sync (latest developement docker image from mikebrady)

When I try to play from Owntone to Shairport-Sync using Airplay 1, it plays for about 2 seconds and then stops for 20 seconds. This behaviour then repeats.

I've used Owntone in Docker before and everything was perfect, but then my HDD crashed and I had to rebuild everything. Playback from iOS devices to the same shairport-sync device is perfect.

I realise this could well be an Owntone/Linuxserver.io issue.

Thanks

Operating System?

Owntone is on - Linux Alfred 5.15.49-v7l+ #1566 SMP Fri Jun 24 19:02:20 BST 2022 armv7l GNU/Linux Shairport is on - Linux Kitchen 5.10.103-v7+ #1529 SMP Tue Mar 8 12:21:37 GMT 2022 armv7l GNU/Linux

Version?

How did you install Shairport Sync?

Docker

mikebrady commented 2 years ago

Thanks. I think you should check with OwnTone, but I’m pretty sure that it is not compatible with the versions of AirPlay 2 that Shairport Sync supports. If you build Shairport Sync without AirPlay 2 support, does it work normally with OwnTone?

kevocl commented 2 years ago

Thanks Mike,

I pulled the Airplay 1 shairport-sync docker image and Owntone plays perfectly to it. I know if I disable RAOP in the owntone.conf, effectively forcing Airplay 2, it won't play to shairport-sync because it uses 'NTP streams'.

mikebrady commented 2 years ago

Thanks -- that's right. AirPlay 2 seems to be capable of using NTP-based or PTP-based timing, but most clients seem to use PTP. While Shairport Sync only has to use PTP signals, an application like OwnTone would have to generate the right signals, and figuring those out is challenging.

kevocl commented 1 year ago

I've contacted the Owntone project about this today.

Interestingly I updated Shairport-Sync - trying both docker and building/running natively - to 4.1-dev-540-g40654624-AirPlay2-OpenSSL-Avahi-ALSA-soxr-sysconfdir:/etc and the music plays for 24 seconds now, and then drops for 2. Which is an improvement, but still not ideal.

ejurgensen commented 1 year ago

Owntone will default to Airplay 1 if it is available, and I suppose SPS AP1 is about the same in the development branch as in master, right?

The logs seems to indicate the connection is idle and there is an alsa underrum. Is that a correct interpretation @mikebrady?

mikebrady commented 1 year ago

Owntone will default to Airplay 1 if it is available, and I suppose SPS AP1 is about the same in the development branch as in master, right?

Yes, SPS AP1 is substantially the same in the development branch as in the master branch, but with bug fixes and changes to accommodate the AirPlay 2 extensions.

The logs seems to indicate the connection is idle and there is an alsa underrum. Is that a correct interpretation @mikebrady?

Yes, the lines:

         3.444795571 "rtsp.c:1281" Connection 28: RTSP connection is idle.
         6.806196664 "rtsp.c:1294" Connection 28: RTSP connection traffic has resumed.

indicate that the RTSP TCP link that governs the connection between the client and the Shairport Sync player has had no traffic on it for about five seconds. It seems to be the case that there should be traffic on it every few seconds, so this might (?) indicate that the client is sleeping; for example, it might be a Mac that has gone to sleep. TBH I'm not sure if it's a reliable indicator. If only we had a specification... 😔.

I am seeing a similar issue with any SPS version greater than 3.3.8. That version works fine on Pi zer0 W and a Pi 4.

The symptoms for SPS versions greater than 3.3.8 is random one or two second dropouts when playing from OwnTone.

I can provide logs from SPS or OwnTone, but I don't know what would the best type of logging to provide so I would appreciate any guidance with that. I can also compile any new code to test as needed.

Thanks for the two great projects that I use every day together.

mikebrady commented 1 year ago

Thanks for the information. Yeah, to begin with, logs from when the problem is occurring from SPS with a verbosity of 1 and statistics enabled would be a good starting point, as well as the Shairport Sync version string ($ shairport-sync -V).

Many thanks.

iVolt1 commented 1 year ago

Hi Mike. Here are my logs. Thanks for looking into this.

3.3.8-OpenSSL-Avahi-ALSA-pipe-metadata-sysconfdir:/etc. I changed vlume a couple of times during this run.

I don't have version info for 4.1 rco but here are the compile flags. 4-1-rc0 ./configure --sysconfdir=/etc --with-alsa --with-soxr --with-avahi --with-ssl=openssl --with-systemd --with-metadata

mikebrady commented 1 year ago

There is some weirdness with the latencies. To explore it, would you be kind enough to add in an extra debug line after line 470 in rip.c, so that it looks like this:

                  if (la != conn->latency) {
                    conn->latency = la;
                    debug(1,"sync_rtp_timestamp: %" PRIu32 ", rtp_timestamp_less_latency: %" PRIu32 ", latency: %u.", sync_rtp_timestamp, rtp_timestamp_less_latency, la);
                    debug(2,
                          "New latency: %" PRIu32 ", sync latency: %" PRIu32

and then build and run it and see what comes back?

iVolt1 commented 1 year ago

Here is the log with the new debug line. I tested owntone with a local music file and it had the same drop outs as is happening from the usual music piped in from librespotjava.

Thanks. This is it with the Music app in iOS as a client:

You'll see that the latency is set once (search "New latency"). When the source is OT, the latency seems to keep changing. I don't know why it should be okay on 3.3.8 but not okay on 4.1, as the code is practically the same, in that SPS looks for the two figures sync_rtp_timestamp and rtp_timestamp_less_latency in the same part of the packet. Maybe I'm missing something. Perhaps @ejurgensen of OwnTone can comment.

iVolt1 commented 1 year ago

Yes, ios spotify to the 4.1 shairport-sync works fine for me. I'll keep trying some things and let you know if find anything.

iVolt1 commented 1 year ago

Hi Mike. I compiled this version and it seems to be working without skips. I will let you know if I have any other details

mikebrady commented 1 year ago

I've just been playing with this too, and the varying latencies are not the problem -- they are odd, but they are not causing the problem. The problem is that Shairport Sync now watches for a "heartbeat" from the player, mainly to see if it has gone to sleep, and it seems as if OwnTone doesn't provide one. So what I'll do is (temporarily) remove the heartbeat requirement timeout until something can be figured out.

Just pushed an update to the development branch with that heartbeat check disabled. If you got a chance to try it out and report back, that would be great. The build numbers are somehow out of sequence, I'm afraid.

ejurgensen commented 1 year ago

What's the heartbeat method? I couldn't see it from the commit, and I'm away so don't have the option of testing.

mikebrady commented 1 year ago

This heartbeat idea is to try to solve the problem of knowing when a client goes to sleep. Consider a scenario where the user is playing a YouTube video in a browser on a Mac laptop, on battery power only, with the Sound Output of the system directed to a Shairport Sync player. If the user closes the laptop, the system will eventually sleep and AirPlay transmission will cease. When it is opened up again, the video may resume, but getting AirPlay to resume properly is difficult because of outdated packets and changes in clock timing (I think). I haven't been able to find any warning or signal that the player has gone to sleep or that it has just woken up. This is where the heartbeat idea comes in.

In classic AirPlay and in AirPlay 2, there is always some traffic on the RTSP connection. In classic AirPlay, an "OPTIONS" message is sent every few seconds by the player, while in AP2, a "FEEDBACK" message is sent every few seconds. Both of these stop when the player goes to sleep, so I figured that their presence or absence would work as a heartbeat. So I added code to wait for long enough to get one of these messages, and if it timed out, it would be a signal that the player had stopped.

Yes, Owntone also can do this, but for AP1 it is only enabled for ATVs, since I only saw them requiring it at some point. Sending heartbeat OPTIONS wasn't originally part of AirPlay, but maybe I should now enable it for all speakers?

Very interesting, thanks. If it wasn’t inconvenient, I think it would be useful.

ejurgensen commented 1 year ago

I think old versions of iTunes also don't send heartbeats. I have an old mac with such a version, I will try with that later this week.

ejurgensen commented 1 year ago

Checked Owntone's code and it seems I misremembered. With AP1, Owntone uses SET_PARAMETER with progress metadata as heartbeat, not OPTIONS. It is also looks to be enabled for all speakers, not just the ATV.

Thanks for checking, and please don't go to any further trouble. I'll experiment with trying to make the heartbeat detection a bit smarter.

Hi Mike. I am still getting this version with the below git command. Is there a newer one I should get a different command?

4.1-dev-602-gf70d9a0f-OpenSSL-Avahi-ALSA-pipe-metadata-sysconfdir:/etc

Thanks.

Yes, that's the right version. Here is a log from my system. I restarted SPS, clicked play three times -- finger trouble -- and played one track from OwnTone on a Linux VM on a Mac to a Raspberry Pi 3B running Shairport Sync.

Is it possible that you got the version string from the just-built Shairport Sync, but that an older version of Shairport Sync is actually running? (I ask because I do this sometimes!)

Hi Mike. Everything continues to work well with 4.1-dev-602-gf70d9a0f-OpenSSL-Avahi-ALSA-pipe-metadata-sysconfdir:/etc. Thanks for fixing it so quickly.

I have done this before also, but I am positive 4.1-dev-602 is running: Is it possible that you got the version string from the just-built Shairport Sync, but that an older version of Shairport Sync is actually running? (I ask because I do this sometimes!)

Congratulations with 4.1, Mike. I have tried it with OwnTone, and it worked fine with Airplay 1. So I suppose this issue and the OwnTone one can be closed?

Thanks! Yes, I guess so.
