Unless you have reference recordings from the PCB, we have nothing to go one because even prior emulation (even if they sound better), might not be correct.

No.06189 Fujix Administrator May 27, 2010, 16:12	It is a clear regression. Music and sounds are being broken at the 1st stage boss, then totally messed up after the stage. I'm checking other games in the stv driver.
No.06190 Fujix Administrator May 27, 2010, 17:07	cotton2 has the exactly same problem as cottonbm. I fix the report description and confirm.
No.06435 MasterBigode Tester Jul 27, 2010, 17:15	The music becomes glitchy much earlier for me, it seems that the music stops playing some samples until the game is reset when a lot of explosion sounds play at the same time.
No.11180 B2K24 Senior Tester Oct 28, 2014, 06:47	Agreed. I tested both sets and it seems like the reported behavior doesn't happen as described, although inaccuracies still exist.

No.11872 Zosite Tester Jul 14, 2015, 20:39	For the record, this issue which indeed existed a while ago is now fixed though I couldn't say when except that it was after 0.148. And I'm talking about BOTH cotton2 and cottonbm in 32 and 64 bit versions. Therefore it should be closed, though currently there are other serious issues to be fixed for this driver and particularly for cottonbm...
No.14937 Kale Developer Apr 10, 2018, 03:01	fwiw it seems to happen through most of the game, including the ending.
No.14967 Kale Developer Apr 19, 2018, 21:27	It also seems to apply to Find Love and in DaiMakaiMura stage 2/3/5 inside Capcom Collection Dai 2. Amusingly: - In Find Love if you save a state then load it sound becomes good. - In DaiMakaiMura BGM can be normally heard in sound test.
