audio level difference between DMA and YM is a known issue, at least on
STE. It should be measured on real HW someday (I have this on my todo
list) and hopefully it will be the same on TT.
As for Falcon, maybe DMA and YM have yet another sound level difference,
as this is a different HW than STE/TT.

Hi,
YM path differs between Falcon and STE/TT.
Later one uses LMC mixer with fixed SDMA vs YM signal level. In case of Falcon, YM is connected through ADC converter with adjustable gain with hardware register: $ff8939
