|Summary||07115: spf2t (qsound): Distortion of sound effects mainly in left sound channel of spf2t|
Distortion of sound effects, mainly in the left sound channel. You will frequently hear distortion in the sound just by letting the game run or by playing. When the game starts and you hear ‘Capcom’ you always get the distortion in the left sound channel. The distortion occurs consistently with many specific sound effects.
Lowering the game volume(s) doesn’t eliminate the distortion.
I did some testing and this distortion is NOT present in mame versions 0.200 and 0.19X. BUT it IS also present in mame version 0.201
|Steps To Reproduce||You can reproduce the distortions every time by running the game or in the game service menu. Some examples - sound code no: 00A0 distorts in the left channel, sound code no: 00D0 distorts in the right channel and sound code no: 0120 distorts in both channels.|

I can confirm that there is a click happening in the cases you mentioned above.
Daily binary testing seems to isolate the issue starting after the HLE QSound updates here on August 18, 2018
