Swfdec - Nov 2008 - [Bug 18616] New: Screeching sound at end of videos

http://bugs.freedesktop.org/show_bug.cgi?id=18616

           Summary: Screeching sound at end of videos
           Product: swfdec
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: plugin
        AssignedTo: swfdec at lists.freedesktop.org
        ReportedBy: macoafi at gmail.com
         QAContact: swfdec at lists.freedesktop.org


At the end of, I think all, YouTube videos, a loud screeching, crackling noise
comes out of the speakers.  An ALSA dev suggested it had something to do with
it not releasing the device properly.

I'm using swfdec 0.8.2 on 64-bit Ubuntu 8.04 with libasound2 version 1.0.15
and
pulseaudio version 0.9.10.

No, that doesn't fix it.

This was my original patch and should work for you too :)

Should that be applied to clean sources alone, or should the previous patch and
this one be combined?

No, that doesn't get rid of it either.

Am I doing something wrong, maybe?  I modified swfdec and recompiled it, closed
Firefox, and opened it back up, then tested it.  Should I be recompiling
swfdec-mozilla after each recompile of swfdec as well or something?
