I have nearly the exact same problem as Oren - but I have yet to experience it happen /while sound is playing/. Only when pandora.com is paused for some time, and I then try to unpause it, does it happen: It seems to play just fine, as do other tabs I open e.g. in youtube - only there is no sound anymore from any flash on that browser.
I have some observations: If pandora.com is the sole open tab having flash running, the problem is fixed by reloading that tab. I believe the entire flash engine is reloaded then (see later). Also (quite obviously if the logic about restarting flash holds) killall npviewer.bin and then reload of tab fixes it. Killall pulseaudio does not fix the problem - on the contrary, I then have to killall npviewer.bin (or reload that frame) to get it to hook up again. Thus, npviewer/flash does not try to reconnect the audio in any way - it does not even seem to notice at all that its sound output is gone - which means that if I use two browsers (firefox and chrome), killall pulseaudio kills audio for both browsers' flash, independently so to speak: Reloading the tab in firefox does not fix the sound for flash in Chrome (yes, the browsers very obviously have one instance of npviewer.bin each). Furthermore, when this happens, watching the Application tab in Sound Preferences, found by System->Preferences->Sound, I can still see the "ALSA plug-in [npviewer.bin]" application that corresponds to the pandora sound, as if nothing was a problem, but there is no sound (If there are several npviewer.bins there, I do known which is which by keeping track of them when they work by using the Mute checkbox (or volume slider), hearing which control which). When I reload the tab, the one line representing that instance of npviewer.bin disappears (but if Chrome has loaded flash with sound, there was two, and then there is just one). It loads up the pandora.com interface (all flash) again, but the line doesn't reappear until the sound actually starts to play. There are several Pulseaudio/ALSA problems in this tracker; I am also affected by the Wine problem at bug 371897, might these be somehow correlated? -- pulseaudio locks up firefox, won't play sound https://bugs.launchpad.net/bugs/497667 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
