Technology for smart line-in processing in an audio environment is disclosed. An example playback device includes a line-in connector for receiving a first audio signal, a network interface, and a processor. A computer readable storage medium has stored instructions executable by the processor to determine that the first audio signal is present at the line-in connector, and, in response to determining that the first audio signal is present at the line-in connector, (i) cease playback of a second audio signal being played by the playback device, wherein the second audio signal is not present at the line-in connector, (ii) cause the playback device to play at least a first portion of the first audio signal, and (iii) cause the playback device to transmit, via the network interface, at least a second portion of the first audio signal to another playback device.
