My previous testing was done on PulseAudio 4.0. I am not sure if this
patch was even meant for 4.0.

I just tested this patch (66962) by itself on PulseAudio 4.99.2.
And I then tested this patch with the patches from 69712 together on
PulseAudio 4.99.2.
Both tests were successful!
Specifically: The patch fixed the flash audio bug ( which was present
without the patch), and sound in general worked on Fedora 20.
