@alberto: so audio is considered to be non-essential in a consumer computer??? I could see that being the case for servers, but computers with gui interfaces ought to consider audio to be essential to that experience, see for instance PC-98 spec.
I did eventually find a work-around for this problem. After I login, if I restart Pulse Audio then it works....
So this is likely to be either a race condition or a permissions problem.
