Thanks Ray and Jayson. Actually I already had the pcspkr in the 
blacklist when observing the phenomenon.

I followed Jayson's advice to conduct a fsck and during my
last reboot (a few minutes ago) the speaker made an intermittent sound 
for 10 seconds and then got muted.

The continuous beep seems to have disappeared, so either there
is something random happening or the fsck has had a positive impact.

Thanks again,
