I seems to solve this bug by the following change (The volume also changes incidentally) :

chinagat.c Line 583:
MDRV_SOUND_ADD("oki", OKIM6295, 1065000)
MDRV_SOUND_CONFIG(okim6295_interface_pin7high) // clock frequency & pin 7 not verified
MDRV_SOUND_ROUTE(ALL_OUTPUTS, "mono", 0.60)

Thanks for reply!

But I found correct sound volume is 0.80.
I uploaded recorded Tuned MAME sound for reference.

MDRV_SOUND_ROUTE(ALL_OUTPUTS, "mono", 0.80)
