I was testing by configuring Windows 7 natively (until now it was only
configured to run from its partition in Ubuntu-hosted Virtualbox) and
I went for a reboot after refreshing the sound drivers. Initially the
default drivers gave silent speakers, but working headphones,
consistent with behaviour under Ubuntu, and after installing the
drivers (but before a reboot) there seemed to be no difference.

However, we may now never know if the problem was the speakers or not.
During the reboot, the hard-drive experienced a total failure (as
reported by BIOS diagnostic tools). The whole unit is now going back
to Dell with both the hard-drive failure and the silent speakers on
the docket, and I'm upgrading to a 24month on-site warranty while I
still can :) Will let you know if there's any change after the
hardware pixies at Dell have done their magic and once I've had
another go at an Oneiric install.
