Tried various kernels but unfortunately to no avail. The happy ending bit: As a last resort I thought I'd try removing pulse / alsa etc. then reboot before re-installing them. I used the remove option in aptitude. Under the impression that I'd removed anything likely to generate any sound I was therefore quite amazed when on rebooting I got the login sound. Not really sure what's going on here but hey a result! Thanks to everyone who offered suggestions.
