The speaker is not polarized. Reversing the two connections should
not change anything.
In the BIOS, there generally is not a control or option for the beep.
The beep should always be there.
On a successful POST, there should be one beep. The purpose of the
single beep, is to tell you the speaker is working. Error patterns
will be a repetitive beep pattern.
It is possible for a speaker wire to get pinched against sharp metal
on the computer case. If the speaker wire has live +5V on it, the
pinched wire can get so hot, that the insulation gets charred.
If you have a multimeter with an ohms scale, you could check
that the speaker presents some loading, like 16 ohms or 32 ohms
or whatever. That would be measured between the two pins with the
wires in them.
Check that the pin spacing on the speaker connector, matches the spacing
on the PANEL header. If you are recycling a motherboard from a
Dell/HP/Gateway etc., it is possible the header design is not the
same as your case wiring.
