Question Ashida Potentiometer volume issue [resolved]

[CosmicRazberry]

Nearing the end of this Ashida build and running into an issue where the volume wheel doesn't work. I am getting fine audio from headphone and speakers, it seems clear just no control. I set the volume type to potentiometer in the RVLoader settings. I have the option to set the volume in the RVLoader menu but it doesn't seem to properly save my settings? And the status page detects UAMP Hud while I am usiing an RVL-AMP, not sure if that's expected? The potentiometer itself looks to be soldered on properly. Right leg has continuity to 1.8v, left leg ground, but I am not sure where the middle leg is supposed to go? It does seem liike it has continuity to the "A" pad on the interface board? The PMS also has an A but thats for the addressable LED according to the diagram, do these A points need to be connected? Using multimeter in ohms between the ground leg and middle leg does show the potentiometer working and increasing/decreasing the resistance value.

I am a bit confused by the diagrams on 4LayerTech. For the analog volume option they show the middle leg to a jumper but that don't exist on the RVL-AMP. Then the note in the corner says the RVL-AMP doesn't have any ADCs for analog control so the PMS handles the communication to the Wii. How does the PMS get this analog information from the Ashida interface board/RVL-AMP? Is this done through the "A" addressable pad? Or is it done over SCW and SDW?

Kinda lost at this point as to what it could be. If any of the vias soldering points were bad I assume something else would be broken like no audio, glitched audiio, not showing up in the status page, no volume control option in the RVLoader audio menu, etc.

I did find this thread related to audio issues: Which mentioned the PMS-lite and UAMP fighting over analog volume control if you link SCW and SDW? However It seems like the RVL-AMP, according to the diagram image, on 4Layer tech doesn't have a controller for audio unlike the UAMP so is the advice different here? When I removed SCW and SDW from the Interfaceboard/RVL-AMP i lost audio all together, while GrazyGadget mentioned in that thread you should not loose audio, just the device showing up in RVLoader.

So turns out I did just need to connect the middle pin to the jumper pad on the PMS. For some reason when I was looking at that diagram I thought those jumper pads were supposed to be on the UAMP/RLV-AMP not the PMS... That's what I get for readiing the diagrams to fast and not paying attention to the rest of the pinouts. I just looked at the jumper pins which the UAMP has a simliiar layout. Thought I was doing pretty good following the diagrams so far but guess we all make dumb mistakes ha. All thanks to Stitches for pointing out what I was missing.
