This sort of think occurred fairly often a few versions ago. My general test was to run alsamixer - check if anything was muted. If not the run 'killall pulseaudio' restart any audio apps then test. If that worked, pulseaudio needs reconfiguring or removing
Only other things I would do is a full system update. Remove sound card, boot, shutdown, add soundcard, boot, test. Hope this helps.

I'm convinced it's a software issue as if I boot from a live CD the sound works OK. I've tried uninstalling / reinstalling alsa & pulse in synaptic to no avail + various terminal commands (doing similar things) found in on-line forums. All to no avail. Is there a way to reinstall the sound system? Can anyone point me in the right direction as to how I should proceed. Thanks in advance for any suggestions.
