Well, this is embarrassing: Since this began I switched the machine on 
even less often than before, but yesterday I found out by chance that 
the sound did not come from the internal speaker but from the speakers 
built into my screen. Now I traced it to the snd-hda-intel kernel module 
(noise there if loaded, sound gone when removed with |modprobe -r|).

Why was the sound never heard on bootup in 3.8.x kernels but is starting 
with 3.10.1?

    Peter.

P.S.: At least now I know that the easy workaround is to tune the 
(hardware) speaker volume down to 0...
