Mac OS X out of sync and disconnects #654

Closed fruitofgeorge closed 6 years ago

fruitofgeorge commented 6 years ago

Macbook pro running 10.11.6 Shairport-sync 3.1.7 running on a CHIP

There are actually two problems happening for me, which looking through the version history notes claim to have been fixed already. Was previously running version 2.8.4 and had neither issue. Only thing that changed in the configuration was updating to 3.1.7.

The first is that playing videos in a browser, such as youtube, the audio is over 2 seconds late. I tested in the latest versions of Chrome, Safari, and Firefox Quantum and all are out of sync.

The second problem is that when navigating to a different video, either through auto-play advancing or clicking a new video in the sidebar, I get disconnected from shairport-sync and system audio defaults back to the internal speakers. A dialog box pops up saying the shairport-sync device is currently in use. This doesn't happen every single time but I'd approximate 70% of the time. I can usually reconnect right away by selecting my shairport-sync device in the system audio outputs again but sometimes it refuses to reconnect and I have to wait the two minutes for the process to time out before I can reconnect again.

Should I just roll back to 2.8.x until things get fully sorted for browser streaming?

Thanks for the post. Actually this is very puzzling to me. I just ran up 3.1.7 on my own CHIP and it’s fine in all respects.

I haven’t tried Quantum, but of the remaining two, only Safari will synchronize the audio in videos from, say, YouTube. Chrome used to do this too, but stopped quite some time ago — at least a year.

Furthermore, even in Safari, if you start playing a video using the normal system output and then switch to AirPlay without stopping the video, the sound will be out of sync. You must stop the movie, switch the output and then resume play.

Regarding drop offs, this is really puzzling, as around 3.1.2, a longstanding drop off problem was resolved — it was due to a misunderstanding of the [unpublished!] protocol.

So, I’m a bit stumped. Is it possible, by some mischance, that 2.8.4 is still running?

mikebrady commented 6 years ago

I should add that the sync between video and audio is not perfect in 3.1.7 -- audio lags about 0.25 second more than it should. It's fixed in the development branch, I believe.

fruitofgeorge commented 6 years ago

Thanks for the reply. I'm sure 2.8.4 isn't still running as I made sure to remove it before building the new version. As a test, I also decided to install 3.1.7 on a fresh RPi I had lying around, which experienced the same issues. I then installed 3.2d22 on the RPi and the sync seems to be fixed but still had the disconnecting issue when clicking to a new video.

I rolled down to 2.8.6 on the CHIP and things are back to normal (except in Firefox which has never been in sync for me.) I feel content to stay here for my daily streaming needs. Honestly thank you for this great tool.

I do still have the RPi up if you have any tests or diagnostics you'd like me to run.

mikebrady commented 6 years ago

Thanks for the update. Certainly, if you could set the log verbosity to 2 and enable statistics on the Pi, let it run for a few minutes on a video and then click through a few new videos, the log would be very interesting.

Alright, so in this log I was disconnected on two occasions. The first was during the first video. I think I didn't wait long enough for the connection to get set up before playing the video so it started way out of sync so I paused the video. When I hit play again it said it was already in use. I reconnected through system preferences and continued playing the video fine. Played more videos for a few minutes, clicking through a couple and the third one disconnected me again. Here's the log:

Jan 31 09:06:09 raspberrypi shairport-sync[10660]: Packet reception interval stats: mean, standard deviation and max for the last 2,500 packets in microseconds:     7969.2,    12072.8,    66427.0.

Comparing the two, what I noticed is in the packet reception interval stats. On your network there are some persistently long and some very long maximum intervals -- up to 465 milliseconds. This makes me think that your network is a bit noisy. A speculation is that it is possible that Shairport Sync is a bit too fastidious -- if the RTSP link is dropped, it immediately terminates the session; maybe it should be a bit more tolerant of a short drop. But it's speculation, so I might add a diagnostic to emit a log entry if the link is dropped unexpectedly. If I did that, would you be kind enough to try it again?

fruitofgeorge commented 6 years ago

Sure, I don't mind continuing testing. I forgot to mention the raspberry pi is hardwired to the network but my macbook pro is streaming over wifi. Living in a major city, the wifi bands are always noisy. Just quickly looking at my network, I'd say it averages around 30dB SNR but can temporarily drop well below that. Let me know when you get a new version for me to run.

PeterPablo commented 6 years ago

I'll also certainly will give this a try. From experience my connection drops from time to time, when walking around with my phone, where I'm streaming from.

mikebrady commented 6 years ago

Thanks guys. I've just pushed a development update with some more diagnostics, specifically if the supervisory RTSP link breaks due to a premature closure or an error. If you could run it at a log_verbosity of 2 and with statistics enabled, then if there are any breaks, it would be very interesting to see what, if anything, shows up in the logs.

mikebrady commented 6 years ago

Quick question -- are you using power-line ethernet extenders? Alternatively, what are ping times like between devices on your network? I'm just curious.

fruitofgeorge commented 6 years ago

No power line extenders. Ping times were pretty interesting. Pinging the RPi 20 times yielded round-trip min/avg/max/stddev = 1.413/20.421/109.763/28.700 ms but I noticed they drastically dropped after 10 pings so I ran it a few more rounds and got round-trip min/avg/max/stddev = 1.276/2.344/14.280/2.713 ms. That's the only hardlined device. Other devices on the wifi were at least double those first figures.

After updating to 3.2d25 things got really strange. It pretty much refused to connect to the airplay server from system preferences. It would appear to connect but then as soon as I tried to play anything with audio it would pop up a dialog box that said it could not connect. I eventually was able to connect directly through iTunes rather than the system audio output. It played music in iTunes fine but then I tried to watch a trailer and the audio came out of the built-in speakers even though it said it was connected to the RPi. Here's the lengthy log from the time while this was happening:

Also out of curiosity I ran an ethernet cable to my macbook pro and results were very similar to the above.

mikebrady commented 6 years ago

Many thanks for these experiments. There is no sign of any specific network errors here and the network statistics look very good. The problem looks like something to do with the logic when a session is terminated and another started right away. I’ll look at that, see if I can reproduce the problem, though I thought it was fixed. Thanks again.

mikebrady commented 6 years ago

Looking through these logs again, I'm seeing stuff like:

Feb 02 21:45:05 raspie shairport-sync[813]: RTSP Conversation thread 4 already playing when asked by thread 4.

This is a logic flaw in Shairport Sync. Hmmm.

mikebrady commented 6 years ago

Looking at the code, one can see that the termination of a session can sometimes take up to three seconds. That might be causing part (most) of the "Already Playing" problem. That issue has been fixed it so that the program can't go for more than 20 milliseconds before checking for termination. Another change is to tolerate repeated "ANNOUNCE" messages for the same stream.

There are a few other changes that [I think] tidy some other small timing issues up, so whenever you got the chance, if you could try the latest development branch it would be great. No rush, and thanks for your efforts.

mikebrady commented 6 years ago

Actually, if you do this, could I request that you enable a new facility to include the time-since-last-message in debug messages? When enabled, each debug log entry lists the time that has elapsed since the previous debug log entry. It is very useful for checking relative timing issues. It was added especially to try to get a better look at this particular issue, but I imagine it will be useful in the future as well.

To enable it, look in the new diagnostics stanza in the configuration file -- there's an example in the /etc/shairport-sync.conf.sample file that is installed when you do a $ sudo make install.

fruitofgeorge commented 6 years ago

Sure thing. I should be able to get to it in the next couple days.

I got around to installing 3.2d26. The good news is I wasn't able to get the "currently in use" while cycling through a bunch of youtube videos.

Also in some testing I wanted to track down at what version the issue first appears for me. I traced it back to the change from version 3.1 to 3.1.1, relating to issue #565. Oddly, my experience is the exact opposite that of shidevil's, meaning it works fine in 3.1 but with 3.1.1 I get the currently in use error. I can't make any sense of it but thought it was interesting.

mikebrady commented 6 years ago

Thanks for all that. I’ll have a close look.

mikebrady commented 6 years ago

So, some headway has been made with the "currently in use" problem. The difficulties in starting up are really quite puzzling. I presume the Mac is both the IPv4 (192.168.111.119) and the IPv6 device [fe80::fa1e:dfff:fee8:7243], right? If so, it looks as if AirPlay itself is misbehaving -- the Mac establishes a connection and without dropping it tries to establish a second one. That's really rather bizarre. Is this behaviour a continuing feature of using the Pi, or do you think it is some kind of transient?

Would I be correct in saying that it seems you started Shairport Sync up, waited about 30 seconds over IPv4 and then attempted to connect to it from the Mac. This is followed by three more connections over IPv6 each lasting around 20 seconds. On thing that I notice is that there is a discrepancy between the interval measured by log's clock time and time measured by Shairport Sync:

This is something I can't account for, but may be irrelevant.

In order to try to generate the errors you see, I'd like to try to replicate the scenario. So, can you say what actions you performed at the start. For example, did you start playing a YouTube movie in Safari and then switch output to the Pi, then switch it back to the internal speaker, etc.?

Thanks again for your help and patience!

fruitofgeorge commented 6 years ago

Yes, that is my Mac's IPv4 and also the local-link IPv6. I was racking my brain trying to figure out why they were communicating over both protocols as I have IPv6 turned off in my router and let DHCP do the LAN routing. Then I realized dnsmasq was still running on the Pi from an old project I thought I had fully uninstalled. Disabling that may or may not have helped some but it didn't fix the problem of both IPv4 and IPv6 starting connections. I ended up installing a new copy of Raspbian Lite from scratch. So here's what I can replicate now: After boot up, I select the Pi as audio output in system preferences. It takes roughly 20 seconds before it fully establishes the connection and uses Airplay for output. Then I go to Chrome and play a youtube video and the audio lags way behind. (Like over 10 seconds behind, for any system audio in fact. For example, clicking play in Spotify you won't hear music until over 10 seconds later.) Then I select the internal speakers for audio output and then back to the Pi again. It connects nearly instantaneously this time and playing a video in Chrome is in sync. The connection process still shows stuff like this in the log:

That's just from the one click of selecting the Pi as the audio output device. It tries from both IPv4 and IPv6 and takes 4 threads to get established.

fruitofgeorge commented 6 years ago

I just disabled IPv6 on the Pi and it still exhibits the same behavior so don't think that is the problem. It still creates multiple threads which get terminated, just now all from the IPv4 address.

mikebrady commented 6 years ago

Thanks again for that. I'll try running up 10.11 on a Mac over the weekend and see if I can get something to happen.

mikebrady commented 6 years ago

The first interactions that look anomalous to me are always IPv6 connections, so you might be on to something. E.g. the third connection in the log of your second-last post:

0.030127000|New RTSP connection from [fe80::fa1e:dfff:fee8:7243]:58412 to self at [fe80::7226:589d:84cc:31d0]:5000 on conversation thread 2.

I don't understand why it should take 18 seconds; it should be quick, like the previous one, which took about 10 milliseconds.

mikebrady commented 6 years ago

Me again. I guess one possibly quick way to check if it's an IPv6 networking thing is to temporarily enable IPv6 on the router and re-enable it on the Pi. That way, all settings would be nominal. If the misbehaviour went away, especially in regard to timing on those IPv6 interchanges, it would be suggestive.

mikebrady commented 6 years ago

Actually, I have noticed that the audio and video is in sync again in YouTube videos played in Chrome. For a while recently, Chrome lost that ability. Nice.

fruitofgeorge commented 6 years ago

I've got IPv6 up and running on everything and still have the same behavior. I also got a "could not connect" pop up message after connecting for the first time and attempting to play audio. Here's the log for that if it's of interest.

Thanks again. Was that a “could not connect” as opposed to an “already playing” message?

mikebrady commented 6 years ago

A quick test: if you turn off IPv6 on you Mac and restart it, does this problem go away? ipv6

fruitofgeorge commented 6 years ago

Yes, I had gotten a could not connect message. I've had them occasionally but can't replicate it at will so not sure what causes it. Thought I'd mention it in case it coincided with anything in the log.

Turning off IPv6 on the Mac didn't change anything. However, I think I've tracked down the cause of the delay in connecting to the Pi and playing out of sync on first play. I had been rebooting the Pi to keep testing consistent but it seems like things aren't fully set up on the Pi before it starts broadcasting as an airplay server. If I wait about 60 seconds after I see the Pi pop up as an audio source before I connect, everything goes smoothly. Trying to connect any sooner than that and I get problems connecting right away and audio plays out of sync by several seconds.

I don't really see that as a bug, more just my impatience and misguidance. I'd say we can close this one unless you'd like to pursue getting the connection set up faster after a reboot.

Okay, thanks.
