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?

This is a PnP card so it will have basically no configuration jumpers on the card itself. For example the joystick port is controlled with Unisound or ESSINIT software. Some ESS cards have no amplifier bypass jumper and require hardware modification, I think this is one of them. There appear to be no jumpers in the circuit path for the TDA1517 chip.

Thank you! So I'll leave them as is.
