Several customers of my plugin WavePlayer are reporting that audio playback in Safari 15 and iOS 15 is "sped up" for a few seconds before settling to the correct rate.
I have just tested this on my MacBookPro with Mac OS 10.15.7 and Safari 15.4 using the simplest createMediaElementSource implementation you could possibly think of (a 16-line script) and can confirm the bad behavior only in Safari, while Chrome, Firefox, and Edge are not affected.

You can test this at the following address:
