I have the same problem on Hardy with either pulseaudio or alsa selected as the audio output module.
On trying to test the sound system whilst VLC is playing, I get: "audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Could not open audio device for playback. Device is being used by another application." ** Attachment added: "lspci_out" http://launchpadlibrarian.net/18081638/lspci_out -- [Fiesty] Sound device is locked when playing a movie in VLC https://bugs.launchpad.net/bugs/128151 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
