I purchased this and I want to set the jumpers correctly (including disabling the amplifier and game port) before I put it in a build. However, I can't find a reference for what the jumpers do or where the manual is. I found some reference here but not for this exact block: https://theretroweb.com/expansioncards/s/labw … on-labsound-810

Is this a situation where I try to map the jumper descriptions at the link I gave to the block or do I just need to find the manual?
