Public bug reported: Both Konqueror nor Firefox are able to play video, but neither produce the accompanying audio. I would expect that the sound for at least system notifications work out of the box. The sound tests in Settings->System settings->Multimedia show Nvidia HDA ALC889A but neither the digital nor audio icons produce sound even with the test. Jack Audio Connection kit produces an error when it is tested.
For example this presentation shows video in both, but no sound: http://dev.medozas.de/files/LCA2010/2010-01-22-Friday/50091.ogv I've tried various Volume levels in the system and applications. I've tried both internal speakers and the audio out jack. This is in a fresh installation of LTS 10.4.1 Kubuntu from CD updated via APT and the online repositories.
