There is not additional sound, I don't understand why.


You're using HACKED copy of Gimmick game (Suikan Pipe). That will NEVER work because Suikan Pipe has music program code disabled (music writes disrupt VRC chip operation).


Maybe somebody can advise? how to enable music code on my hardware without VRC conflict?

Not using a VRC chip is the easiest solution.

Unfortunately anything you write on the ROM region will end writting to VRC registers. Gimmick! uses a area which on FME7 and Sunsoft 5a are empty so no conflicts happen.

And anyway Suikan Pipe is a horrible hack because it has bad music anyway (VRC can't bank the DPCM region so you get bad DPCM sound).

Find a FME7, 5a or even 5b cart without sound (Some Gremilins catridges had 5b inside without using the sound part) cart to make your Gimmick! cartridge.
