1731813 - Playback of .mp3 file as a MediaElementAudioSource hiccups at start

Status: NEW

(Core :: Audio/Video: Playback, defect, P3)

Description

[Jukka Jylänki]

STR:

1. Visit http://clb.confined.space/audio_test_suite/8bit_detective/8bit_detective.html (or git clone the site down for local examination from https://github.com/juj/audio_test_suite )
2. Click the last button on the page '8bit_detective_8000hz_mono_lame3.99.mp3'.

Expected:

The page should play back a seamlessly looping audio file as a MediaElementAudioSource with loop: true.

Observed:

The audio starts playing, but then immediately after ~1/3 seconds, has a hiccup/glitch, and then resumes to play normally. (Compare against the other audio formats for reference)
