Revert "Shiny Drum Machine doesn't play in TRATS device."

[Issue]: WEB-3340
[Problem]: Audio playback is delayed for 5 sec if ConvolverNode takes longer time to process audio
[Solution]: Revert this patch to play the audio continuously without any break

This reverts commit 921475cf76b500b4730f9b4f3e76a96da45a154a
