Maybe not. It looks like Parag may have been seeing a combination of two
different issues: the one that Peter fixed and one related to group
scheduling.
As I had group scheduling disabled, I only saw the first one. But my audio
skips were a lot less severe than Parag described. And disabling group
scheduling helped solve the problem for him.

So it may well still be worth following up on this.
