Thanks for the report. Could you run:

and post the results here please?

(Please notice that it's a small v, not a capital V.)

Super, thanks. That looks alright. Could you now try:

$ shairport-sync -v --statistics

and try to play a track for maybe two minutes and post the log, please? You should get extra lines, something like these:

[mikebrady]

Thanks again. This is a mystery -- there is no sign of a connection being made to Shairport Sync at all. So, could you kindly increase the verbosity of the debugging:

$ shairport-sync -vv --statistics

and try again, please? We might see the attempt to connect being made.

[hassbian-ABC]

meaning no response

[mikebrady]

Can you say what system you are playing from please?

[hassbian-ABC]

iphone13 ios17

[mikebrady]

What is the name of the player?

[hassbian-ABC]

Always' no response', even if you haven't played

[mikebrady]

What app are you using to play the track? I don't recognise it from the screenshot.

[hassbian-ABC]

DS player , I tried to play using Apple TV connection and got the same result

[mikebrady]

Thanks again. Is there any possibility of using Apple's own Music app to see what is does?

[Update] Or Spotify...

[hassbian-ABC]

Even if I don't play any music and restart the service, it's still 'no response'

[hassbian-ABC]

Normal on iOS16

[mikebrady]

Thanks. I'm running it with iOS 17 devices without problems.

Do you have any firewalls or VPNs running on your systems or network?

[hassbian-ABC]

No, in the same network environment, everything is fine with iOS16

[mikebrady]

Thanks. Let's see if we get more reports like this -- I'm afraid I don't have any more ideas to try out.

[hassbian-ABC]

Connection and playback are normal, except for no response in home app

[hassbian-ABC]

Even if there's no music playing

[mikebrady]

Ok, now I'm beginning to understand your problem! Those screenshots are of the Home app, and not the iPhone or DS Player, etc., right?

Let me respond a little more later on...

[hassbian-ABC]

Yes，Except for the 'no response' in Home app, everything else is normal

[mikebrady]

Okay, that's also happening to me too, and I guess it's an iOS 17 thing. Unfortunately we don't have a good idea of the supervisory information and metadata information protocols that control this, so it may not be something we can fix.

"Non risponde" is Italian for "no response".

[hgaogao]

Have you found a solution again? Me too

And I also found that the iPhone will have this prompt during the process of switching from iPhone to iPad.

This is my build parameter.

[mikebrady]

Unfortunately not. It is a bit frustrating, but as mentioned above, we don't have a good idea of the supervisory information and metadata information protocols that control this, so it may not be something we can fix.

The message "Unable to play..." seem to be transient; when you try to connect again, the connection usually works.

[hgaogao]

Yes, it will work fine when you connect again
