An example computer system identifies a capability of a playback device to reproduce audio content. Based on the capability, the computer system identifies a first version of audio content for playback by the playback device and causes the playback device to play back the first version of audio content. While the playback device is playing back the first version of the audio content, the computer system detects a change in a network connection between the computer system and the playback device. Based on the detected change in the network connection and the capability of the playback device, the computer system identifies a second version of audio content for playback by the playback device and causes the playback device to transition from playing back the first version of the audio content to playing back the second version of the audio content.
