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)
