4 years ago Thanks for the interesting post. Hmm -- can't see anything untoward there alright. Could you enable statistics, maybe turn the log verbosity down to 2 and let it run for a while (say about three minutes after the audio stops) -- we might get to see if audio is actually arriving at Shairport Sync.
YouTube on iOS has always been problematic from the AirPlay perspective; haven't tried it from an AppleTV.

4 years ago Same issue here, only started appearing a few days ago, maybe with the new version of tvOS. Youtube sound from apple tv stops after a second or so. Sounds from any other app from apple tv work fine though. Perhaps its related to dynamic adaptive streaming of youtube.

3 years ago Hello Mike, thank you for this great application. I have also the same issue with youtube app on appletv, other apps like Netflix working like a charm. First i tried different settings, ignore_volume_control, keep_dac_busy, disable_synchronisation ... youtube still not properly working Next step was to switch to libalac and self compiled shairport, but this issue still exist. Its also no matter is a DAC or internal sound card will be used. Also audio configuration on apple tv (16bit, only stereo, reset airplay calibration) will not help. Do you have any other idea?
My log is attached.
[Edit: log file attached as file instead of text paste]

3 years ago Thanks for the posts, @andru79 and @jacobxdouglas and @bertrand-lupart. I don't have a recent Apple TV, I'm afraid, so I've let this slide. @andru79's log file shows nothing unusual at all -- in fact it shows output for a longish play session. Similarly, I can't see anything peculiar about @bertrand-lupart's log. As soon as I can get hold of an ATV, I'll have a look at this. It really does seem to be only the YouTube Apple TV App.

3 years ago According to this thread: https://discussions.apple.com/thread/251934651 it seems to work with Airplay 2. I have the same issue both with shairplay-sync and and while using an older Apple TV that does not support Airplay 2 as a receiver.

Thanks for that. More and more, it looks like a fault in the YouTube app.

3 years ago This was always an issue for me with the Youtube tvOS app. Now it just started on the Youtube TV app which prevents me from watching TV with any sound. Is the fix here to update to airplay 2?

3 years ago Just clarifying, when it is said it only happens with Airplay 2, that is saying that Shairport sync is only Airplay 1, rather than saying YouTube needs to be on an airplay 2 device e.g. AppleTV 4.

3 years ago Maybe interesting to know is that the youtube kids tvOS app does works (for same content). Surprised that this bug is still present after months, will all airplay 1 users have this problem?

3 years ago @mikebrady Hereby some additional verbose logging (not sure if it contains any error related info).
After a short idle period and commercial: 22:11:13 the actual video starts including audio 22:11:23 audio drops (video keeps running)
shairport-sync-youtube-verbose.log
YOUTUBE APP Version: 2.06.21.00/web_20210330_00_RC00 Device: TV (PLATFORM_DETAILS_OTT), Apple/AppleTV5-3/0, Cobalt (21.lts.4.300527-gold),AppleTV(14.5)
Shairport-sync software version: "3.3.7-libdaemon-OpenSSL-Avahi-dns_sd-ALSA-stdout-pipe-soxr-metadata-mqtt-sysconfdir:/etc"
I hope this logging provides some information, maybe something we can report back to YouTube. If I could try something out, please let me know.

3 years ago Just adding I see this - tvOS 4.7.
pi@raspberrypi:~ $ shairport-sync --version 3.3.8-libdaemon-OpenSSL-Avahi-ALSA-soxr-sysconfdir:/usr/local/etc
Only with YouTube.

commented
3 years ago Thanks. Pretty sure it's an AirPlay 1 issue. In case you missed it, Shairport Sync offers a limited AirPlay 2 functionality on the development branch.

3 years ago [UPDATE - no audio from my Apple TV, but works from my iPhone. Both 14.7 - weird]
Thanks. Just rebuilt for AirPlay 2 to test - but I must have done something wrong as I'm not getting any audio output now (using Movie app to test, not YouTube). Works fine if I switch back to the earlier version of the executable and I've checked the volume is turned up.

[Update] Yes, AFAWK AirPlay 2 support only works from macOS or iOS. It partly works from a HomePod, and we believe that it does not work from an Apple TV. Apologies if it is therefore inapplicable in your situation.

2 years ago Shairport Sync now seems to work well (when built for AirPlay 2) on AppleTV. Make sure you are using the latest development version of Shairport Sync and the latest development branch of nqptp.
Thanks.

AirPlay 2 support in still only the development branch, but that fix is in it and seems to be working well. Tested on the YouTube app on an Apple TV 4K fully up to date.

Hello,
I'm using shairport-sync on a Raspberry Pi plugged into a stereo with the jack port, and it works great ! iPhone, MacBook, Apple TV… can play sound to the stereo via shairport-sync. Thank you for that !
Everything's working perfectly, except for the YouTube app on the Apple TV : the first second on each stream comes to the stereo, then silence. First second of each ad, each video, or each time the video is time warped using the seek bar.
Everything's up to date :
Interestingly, no sound issue streaming from the YouTube iOS app : YouTube iOS -> Airplay 2 -> Apple TV -> Airplay -> shairport-sync
Can't find any error in the shairport-sync logs below (video launched at 21:41:00)
My guess something's wrong with YouTube tvOS app, since other people are reporting issues with Airplay speakers :
But I'd be happy to help troubleshoot if needed.
Thank you,
