iTunes keeps playing sync sound effects during music playback
I'm running iTunes 12.5.4.42 on a Windows 10 PC. On the same wifi network, I also have an iPhone 6S and an iPad, both running iOS 10.2.1. Wifi sync is enabled.
I just bought a new album in iTunes, and am trying to enjoy it. However, during playback from my PC in iTunes, iTunes keeps playing the sync sound effect over and over again. It sounds at least once every five minutes. This is very distracting during music playback so it's rendered my iTunes unusable for playing music. I am not touching the sync settings for either iOS device, and they are not connected via USB. It just won't stop making this sound.
