VLC Will Not Play PCM/L16 Audio

Does anyone know why VLC will not play the PCM-L16 (WAV) format? Tried the “http://<ip address>:5901/stream/swyh.wav” and there is 1.5Mb of data passing but no audio. I’ve tried this on Mac, LINUX, and Android versions of VLC. MP3 works fine. Windows Media Player plays the WAV stream fine.
