So what is the status of this now? I have Edgy, flashplugin-nonfree (as far as I can tell, this now installs Flash Player 9), no esound-clients, no ALSA dmix hack, libesd- alsa0 installed automatically (I presume because flashplugin-nonfree Recommends: it, perhaps others too) ... and I still experience intermittent problems with Flash sound in Firefox. It seems that some time after I have visited YouTube or other Flash video sites, sound is hosed. I have been unable to pin this down exactly; my recollection is that occasionally the sound would simply stop working between two YouTube videos.
I was pointed here by a comment in /etc/firefox/firefoxrc (see also bug #94392 ...) while attempting to solve these problems. By default my FIREFOX_DSP="none" and the comment warns about changing it to "auto" or "esd" but I went ahead now and changed it to "auto" anyway. Is that comment still topical and correct? So far, things seem to work for me, although I have not stress tested anything yet. -- Sound does not work properly in Flash in firefox https://launchpad.net/bugs/29760 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
