Why do I have audio problems when one of my connected devices is a Mac computer?

You may experience audio problems during playback if you have two devices connected and the one on standby is a Mac computer. If you experience this, try the following:

Make sure you pause or stop the playback on the Mac computer.
Turn Bluetooth off on the Mac computer.
On the Mac computer, select “Don’t use this device” from the Bluetooth preference pane in System Preferences.
