My guess is that the problem was with a soldered-on button piezo speaker,

There is no piezo. Just the white PANEL header in the lower left corner of
this photo. The SPKR pins are on the lower right of the PANEL header.
Four pin spacing (as shown in the manual).

The OP got the buzzer/tweeter with his Lian Li case, it didn't come on
the mobo.

I got a buzzer with a Cooler Master case and it was just what I needed
for the mobo the case was intended for.

I assumed that the 'industry' practices or standards were that the
responsibility for the mobo speaker lay with the case mfr/supplier, like
the little case wired coil speakers of the past, and that the case
people had assumed/ taken on/ the responsibility and decided to save
money with little buzzers to 'stick onto' the mobo.

Just to clarify the situation the existing buzzer is the same as shown on
the link that Vanguard supplied: http://www.pcpartscollection.com/mosp.html

I managed to source a replacement from an old computer a friend had in his
garage but I'm afraid it made no difference to the volume.

I'm an elderly person with some hearing defect so to check that it wasn't
my hearing I got my wife (who can hear a pin drop at 50 metres) to listen
when I booted up. She remarked that though she could hear the beep it was
faint. I then tried three other computers (friends) to see if the volume
was better or the same as mine, and found that they all had very faint
buzzer beeps. In fact the owners of the other computers were unaware that
computers beeped on boot up and had never noticed a beep when booting the
computer.

I read with interest the points that Paul made, but my expertise is not up
to changing the motherboard circuit wiring. I wonder is it possible to
amplify either a cone speaker or a piezo buzzer, between the motherboard
connection and speaker/piezo?

The unit that I linked to that showed a 4-pin connector to a bud buzzer
meant you were using the 4-pin mobo header for the speaker connection. That
should handle a *small* 8-ohm speaker. It looks like you have a flaw in the
mobo regarding the driving circuit for the speaker.

Oh well, if you didn't know what the beep counts meant (long beeps, short
beeps, how many of each) then you aren't losing anything important to you
that you could do anything about. Once the OS starts loading and it loads
the audio drivers, your external speakers are going to get used, anyway.

I never mentioned anywhere in my messages that implicated I was unaware of
the error beeps, I might not be an expert but I have been building
computers since 1991, but thanks for the interest you've taken with my
small problem.

I know some Dells use the externally attached speakers for the warning
buzzer instead of using one like you have. The POST beeps come through the
powered speakers (so obviously you must have them powered to hear the
beeps). I haven't bothered to read the online manual for your particular
motherboard to see what it might support for sound issued through the
backpanel connectors.
