Don't see this on my configuration; I suspect this only happens on a subset of machines with a particular configuration.  Would you mind posting the following details:

- Result of running dxdiag.exe and clicking "Save All Information"
  (I only need the audio related bits, so feel free to delete anything else from the resulting txt file)
- In the Sound control panel, right click on the "Default Device", select Properties, select the Advanced tab, and let me know what the "Default Format" is set as.

Thanks!

A couple of other things I forgot to ask:

- Do you see this every time you play media, or only the first time after the browser is started?
- Can you please repeat your test using the set of files here: http://flim.org/~kinetik/tests/bug1176499/
  (it's a simple 5 second sine wave encoded in various sample formats)

Thanks!

I see this issue only the first time when I play the movie,
restarting browser make it occur again.
Sometimes is reproducible even without restart,
when delay between playing movies is very long.

I can reproduce it on all samples. I tested only one sample and the next one after browser restart.

Adding a tracking flag for FF41.

Comment 7

[Matthew Gregan [:kinetik]]

Thanks for the additional debugging information.  I don't have an immediate solution, and since the change causing this was a speculative fix I've backed it out in bug 1103824 for now.

Virtual_ManPL, is this still an issue for you on latest Firefox41 (on Beta channel)? Thanks!

Comment 9

[Virtual_ManPL [:Virtual] 🇵🇱 - (please needinfo? me - so I will see your comment/reply/question/etc.)]

No, because patch which caused this issue was backed out per Bug 1103824 Comment 14 and Bug 1103824 Comment 15.
I will untrack Firefox 41 and also change its status.
