Today I was adding sound to an LGB 22801. In doing so, I removed the existing decoder (LGB 55021) and replaced with an MD Electronics Drive-M (which I use in most of my locos) + SX6 Sound Card.
This was essentially ready to go given it previously had a decoder so moved everything over and it worked on default. However, when I tried changing CV values, I had a ~10% success rate without any particular rhyme or reason. To troubleshoot, I removed the pins that connector the wheel/motor block from the onboard circuitry and connected them directly to the decoder. This worked every time.
I was planning to leave it like this until I realised that without the motor block (GN, GE, WS, BN) being connected to the circuitry the functions (such as lights don't work) - I assume they're being used in some way.
My options as I see them right now:
Has anyone else experienced something similar?

My options as I see them right now:
- Simply remove the onboard circuitry and wire everything straight to the decoder (as I usually do)
- Test splitting the connections from the motor block to connect directly to the decoder and the onboard circuitry
- Ask here if anyone else has suffered from problems before and hope I've missed something obvious.
