1. A playback device comprising:
at least one amplifier configured to drive an audio transducer;
one or more processors; and
data storage storing instructions that, when executed by the one or more processors, cause the playback device to perform operations comprising:
receiving, at the playback device, first audio data from a video display device;
receiving an indication from the video display device that the first audio data is encoded in a compressed audio format;
selecting a decoder from among a plurality of decoders;
decoding the first audio data using the selected decoder;
playing back the decoded first audio data via the playback device;
while playing back the first audio data, receiving, at the playback device, second audio data from the video display device, the second audio data encoded via an uncompressed pulse-code modulation (PCM) format;
determining, via the playback device, that the second audio data is encoded in the uncompressed PCM format;
based on the determination that the second audio data is encoded in the uncompressed PCM format, delaying playback of the second audio data for a period of time; and
after delaying playback for the period of time, initiating playback of the second audio data.
