If you don't have in audio in Adobe Flash in Fedora 20, pulseaudio is the reason

If on your Linux PC YouTube wouldn't play more than one second of videos, while flash on other websites has no sound, or you have any other issues with audio in other apps, the likely culprit is Pulseaudio. I could never figure out the reason why the world needed pulseaudio, apart from the fact we have to use everything that Lennart Poettering creates.

Anyway, solution to the pain is easy, just follow excellent 30-second instruction on Mondo Grigio blog.
