Comment 12 for bug 221038

@Alex,
Flash doesn't appear in pavucontrol because it doesn't use pulseaudio.

I couldn't reproduce your problem. I paused an video in Totem for 10 min and nothing happened. I was able to start the playback without any problems.

Could it be that the problem is caused by the flash player?

@Benjamin Drung,
As it seems, xmms2 doesn't support pulseaudio in hardy.
I have seen a package in intrepid that should deliver support for pulseaudio. (xmms2-plugin-pulse)

In conclusion, I would say that these problems are related to software that isn't able to use pulseaudio at the moment.

Regards
Achim
