Been having airplay disconnects for a coupe versions and have reported those issues as well as provided log files.
I have also been getting since this latest update (static) buzz (zapping) sounds infrequently. It’s very jarring and annoying.
Note: I Airplay Spotify from my iPhone7 to RPi3 / Audiophonics I-Sabre V3 ES9023 TCXO DAC over my WiFi network (Asus RT-AC87U router).
Here is a log for when buzzing happening, stop playing, tried to play again but Volumio airplay service was gone, volumio web site still running.
