Lag: The lag is mostly attributed to the initial buffering of audio on the device side. All streaming media players buffer audio to overcome network glitches, etc. The size of the buffer and subsequent duration of playback delay will vary by make/model of playback device. You could delay the sound on VLC player.

There is a 70ms time delay when processing the audio through the PLAY:5. The uncompressed audio setting will result in the least amount of lag time with the unit.
