An example playback device is a first playback device in a media system. The first playback device is configured to resolve audio conflicts with one or more other playback devices in the media system by: (i) capturing, via a microphone of the first playback device, audio content played back by a second playback device, (ii) identifying the second playback device as a source of the captured audio content; and (iii) responsive to identifying the second playback device as the source of the captured audio content, altering a playback characteristic of the second playback device or the first playback device to reduce an audio interference between the first and second playback devices.
