Comment 91 for bug 450684

Worth noting for anyone following this bug who is seeing problems: make sure you're running a current version of PulseAudio. The version shipped with F12 has a bug that causes the hanging snd_pcm_writei that I ran into in this bug (comment 69), but an update to 0.9.21-5 is available in Fedora updates. There's a bunch of investigation of this specific problem over in bug 573924 for the curious.
