--- Comment #29 from webkit at nuclearsunshine.com ---
I don't think it's a playback speed issue with the Absolute stream it sounds like it's just not successfully getting ~ every second packet for the first few seconds, and then playing the remaining (buffered) ones without any gaps for the missing packets. So it's normal pitch, but sounds "double-speed" (i.e. like a "time stretch" high-speed playback, rather than a "chipmunk" high speed playback).

Are you hearing something different from that? I just re-tested and it's still doing the same thing on that stream.

I suspect that the behaviour (no silence inserted for missing packets) is the same on the other streams, and it' just there is a lower ratio of missing packets for the glitchy few seconds on the other streams. So something like:

Absolute: 13579 etc. (10-packet section played back in 5-packet time)
Others: 12456790 etc. (10-packet section played back in 8-packet time)

Instead of:

Absolute: 1.3.5.7.9. etc.
Others: 12.4567.90 etc.

Where "." represents a one packet-duration silence.
