So I encountered this card - https://arvutimuuseum.ee/th99/i/M-O/52700.htm

Nothing really interesting, but note the default jumper settings - apparently it's recommended to short pins 19 & 20, 23 & 24 on the Wavetable connector if no daughterboard is installed.
And I've even found a random photo of that card where the jumpers are actually there:

The attachment un6868.png is no longer available

They are supposed to short Audio R and Audio L coming from the daughterboard to GND - to reduce noise, I guess.

So, do YOU ever care to install those jumpers?
If yes - did you ever notice any difference?

In 2003, I voted in favour of joining the European Union. However, due to recent developments - especially the restrictions on cash usage - I'm hereby withdrawing my support. DOWN WITH THE EU!

It is about noise reduction, but it isn't something I have tried to test myself to see how much difference it makes if any.
