Demonstration of the Pops. There are 2 pops at the start, then it's all good.

This issue is not happening on Safari 15.6.1 on Intel and as I recall I did not experience this before 16.2 on M1. Does not happen on Mozilla nor Chrome.

These pops - as can be heard at the beginning of the example - mostly happens once an Audio Context is activated, following a page refresh. Happens inconsistently but a pop is guaranteed in every 3rd page refresh. Sometimes it only comes from one channel (right or left). The amount of these pops(some are lighter and smoother) never exceeded 2, then the App functions without a hick, it is as if the engine is warming up.  

I have added some latency to the buffer playback scheduling to make sure my code is not blocking CPU by any means but the pops persist.
