Ok, I've done my test again (attached) and I have to admit that 0xc1ff/0x8000 doesn't change LMC mixer setup. 
I just wrongly interpreted my previous tests (I reused a part of code from my another application and  just didn't take into account LMC setup from it).

LMC_0B set Input 1 (mix DMA+YM equally) and then set 0xc1ff/0x8000  - here YM is audible
LMC_0B1 set Input 2 (only DMA, YM muted) and then set 0xc1ff/0x8000 - here YM is not audible

Therefore it seems that 0xc1ff/0x8000 is just ignored by LMC.
