Observed in STP 113 and iOS14 GA. Does not occur in Chrome or Safari 13.
When using a Web Audio graph of the form:
(BufferSource) -> (MediaStreamDestination) -> (HTMLMediaElement)
disconnecting the BufferSource from the graph causes a malfunction, and garbage audio to be fed to the HTMLMediaElement. Setting HTMLMediaElement.srcObject = null works around the issue.
I am able to reproduce. Thank you for the reproduction case, I will investigate.
This is a regression from http://trac.webkit.org/changeset/265280.
