I followed the advice of the following bug : https://bugzilla.mozilla.org/show_bug.cgi?id=378155
Added esound + dependancies, which forced a removal of pulseaudio- esound-compat and now sounds do play correctly in Tbird. I don't know to what extent the removal of pulseaudio-esound-compat will have an impact on my environment though. But I do have sounds back in thunderbird now. ** Bug watch added: Mozilla Bugzilla #378155 https://bugzilla.mozilla.org/show_bug.cgi?id=378155 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/732572 Title: New Mail Notification Sound does not play in Natty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/732572/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
