Loss of Sound

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

Try renaming your pulseaudio config directory, so it gets recreated on next boot.

I’m not au fait with how Debian implements pulseaudio, so can’t tell you exactly where that directory is located … but if you post the output from:

ls -a ~/ | grep pulse


ls -a ~/.config | grep pulse

I might be able to tell you
