Hi!
When trying to play an <audio> element through Web Audio using createMediaElementSource, I hear cracking noises at the beginning of the audio.
I have tested this with Epiphany on a linux desktop using "flatpak run org.gnome.Epiphany.Devel/x86_64/master" and also on the latest WPE. On Firefox the audio plays clearly.
I created an example here: http://softbot.avner.us/test/media-element-source.html
It happens both when streaming the audio and also when referencing a file through a direct path, as in here: http://softbot.avner.us/test/media-element-source-file.html
When using a buffer source from "decodeAudioData", the audio plays clearly.
Thank you!

/Avner
