Pulseaudio sometimes plays music too fast/high-pitched

Description of problem:
Sometimes, pulseaudio sometimes plays music faster and high-pitched than it should be (like 44.1 audio on a 48khz device or something like that). Doing "killall pulseaudio" and restarting playback fixes things, which is why I suspect a pulseaudio bug.
This appears to be a regression since Fedora 17 (I jumped over Fedora 18), where this never occured to me.
I had the problem occuring with both audio opened directly in a Google Chrome tab (chrome probably uses liboggplay or ffmpeg or something for that), and with the adobe flash player.
Sorry I encountered both of this with just proprietary software, but since chrome and the flash plugin are probably sufficiently separate in their audio handling, I assume a pulseaudio cause is likely. However, so far it did not occur to me with other software (I do the majority of my audio playback inside the web browser).
Version-Release number of selected component (if applicable):
Name : pulseaudio
Arch : x86_64
Version : 3.0
Release : 10.fc19
Kernel version: 3.9.4-300.fc19.x86_64
Happens every 1-3 days, a "killall pulseaudio" and reissuing playback makes it go away.
Steps to Reproduce:
1. Leave computer running for a long time, play music at various times
2. After a longer break with no music, play music in Google Chrome directly in a media tab, or on Youtube with Adobe Flash. Doesn't happen always
Music is high-pitched and faster until "killall pulseaudio" is issued
Music is normal as always
Interesting, I have to say I noticed this too recently, and also only in the scenario's you mentioned. For me, primarily when playing 'Angry birds friends' (flash) on chrome.
I wonder, if resume/suspend cycles may be relevant... I'll try testing that, and report back if I find anything.
This message is a notice that Fedora 19 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 19. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 19 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
