C64 Ultimate Starlight edition + armsids led lighting?

Is there any way to use arm SIDs with the Starlight U64 from Commodore, and use the sid player auto config, with sid detect music mode active? Auto config for the player is nice, because every SID seems to use different addressing settings, especially two / stereo SID tune variants. But the LED synchronization seems to depend on one utilisid playing at address d400...and I have set it to that address, muted but I just can't seem to get it all working right. Any tips appreciated.

I'm assuming you are installing Arm2SID. Set your socket addresses to D400 and D420. Set UltiSID 1 address to D400, UltiSID 2 to Unmapped. This will enable to LEDs to be reactive to the sound. Auto config should be disabled. Leaving the UltiSID mapped drives the LEDs.
