Description of problem: I know Flash is not supported as free software, however, the presence of libflashsupport suggests that there is some interest in getting flash to work on Fedora. To that end, I followed the instructions on http://macromedia.mplug.org/ to test Flash 10 (beta) on a x86_64 box. As suggested on that page, I removed libflashsupport. I got the following results. A) If browser+flash is started when no other application is playing, sound in flash works fine, however, I cannot use any pulse audio application. Mplayer reports error AO: [pulse] pa_stream_write() failed: Connection terminated,?% 5 0 AO: [pulse] pa_stream_get_latency() failed: Connection terminated Even after the browser and flash processes are killed, I get the error until I delete everything inside ~/.pulse/ B) If flash is started while another application is running, I get no sound in flash, but I can use other pulse audio apps just fine. What debug information should I provide to diagnose the problem?
Please run "pulseaudio -vvvv" in a terminal. Then do your testing and paste the output of that call here. (you might need to kill the running PA instance first by issuing "pulseaudio -k")

Hmm, this dump shows that access to your audio device is blocked because some other applications uses it. Please figure out which one that is, and terminate it. Then start PA again. Because no audio device is initialize PA will initialize a null sink, which however then causes a failure, which is already described in bug 462203.
I assume that application is Flash wrapped inside NSPluginWrapper. However, Flash 10 is supposed to work with PulseAudio without the need of libflashplayersupport (at least on i386 I'd assume). I am wondering if they (Adobe) cannot handle x86_64, and libflashplayersupport needs to be updated to support Flash 10 and x86_64.
Anyway, this is mostly a duplicate of bug 462203 and the other issue is not a bug in PA. Closing. *** This bug has been marked as a duplicate of bug 462203 ***
