'Popping' Sound when playing WAV over DLNA
Updated by Russell Samuels on Jan 5, 2014
Some AV receivers like DENON AVR-3808CI will make a noise towards the end of a track
when playing a WAV file over UPnP/DLNA. This occurs in receivers that interpret metadata
(specifically the LISTINFO chunk) within a WAV file as audio data.

The workaround is to use FLAC (another lossless codec) instead of WAV, the benefits being
that there are rarely compatibility issues with WAV files, more metadata can be stored
within the file, and the file size is smaller, without compromising audio fidelity.
