Some before and after sound recording would be great here - along with some original pcb recording/video displaying it's proper output. Sound emulation for the whole driver is known to not be 100%, even if it had glimpses of being good.

Uploaded sound files of "before and after". The woman's voice varies every time.
It sounds the blank parts of the man's voice sample are distorted.
Also in danhiq, the sound test SEQ 8 has the same distortion.

MASH, this time I set this report confirmed as it is regarded as a regression, although, please be noted that it needs more preparation for a bug report especially in a game with the imperfect flag, usually we don't accept reports except heavy regression for those games.

Thanks in advance.

Fixed in mame 0.143u? any intermediate version between 0.143 and 0.144.

However, it can only be checked untill 0.148u1 because in this version a worse bug appeared:
