Can anyone please help with the following problem ? The sound on a desktop PC running Debian Jessie has stopped working - no sound from any websites (e.g. BBC or YouTube) and trying to play a standard sound file I have saved which is used to test the sound with vlc gives: Audio output failed: The audio device "default" could not be used: Device or resource busy. and in the terminal window it says: VLC media player 2.2.6 Umbrella (revision 2.2.6-0-g1aae78981c) [00000000013f0608] pulse audio output error: PulseAudio server connection failure: Connection refused [0000000001318118] core libvlc: Running vlc with the default interface.
