2 years ago Thanks for the post. Verbosity of 3 is too much -- a verbosity of 1 or 2 is fine, thanks.
It it possible that you were alternating the AirPlay 1 and AirPlay 2 versions on the same machine within a short time of each other? I know that clients such as the Music app get confused by this -- it seems to take a good few minutes to settle down.
If you enable statistics and a verbosity of 1, you should see if/when a connection is made to Shairport Sync, something like this:
Aug 27 11:51:03 ubuntu2004 shairport-sync[867]: 2.981795376 "rtsp.c:3154" Connection 3. AP2 Buffered Audio Stream.

...It may also be an AP2 Realtime Stream, beginning like this:

What happened?
I recently decided to try out the latest Shairport-Sync development version to see how Airplay 2 was working.
I built it on a Raspberry Pi Zero W with the latest Rapbian Lite OS. everything seemed to go smoothly and had no trouble building and installing. I connected to it from an iPhone 11 pro with IOS 15.6.1 and it played sound through the USB DAC. Then, I disconnected and could not reconnect again no matter what I did (stopping, restarting, reinstalling, etc.) Every time I try to connect the phone just says "unable to connect". If I remove it and install the normal shairport-sync airplay 1 package it works fine. I also have raspotify on there it plays just fine as well. I have no clue.
I attached a log of a failed connection attempt with the verbosity level set to 3.
