Unhappy VSYNC makes sound go nuts!

In all v0.8.22Rn releases so far, enabling VSYNC causes sound problems.

All the games/cracktros I tested in NTSC mode, the pitch increases like half an octave, and breaks up / skips badly.

In PAL mode, about half the games suffered from the break up / skip, but pitch was correct.

Messing with the driver lag slider does have an effect, but not enough to correct the pitch.

Increasing frameskip to four cures the break up / skip, but not the pitch.

Disabling VSYNC corrects the sound problem completely, but then it's rip-ville. Switching to desktop mode does, too, but that's no fun!

Activating / deactivating PowerStrip has no effect.

I run in 16-bit modes, 720x480 60Hz for NTSC, 720x576 50Hz for PAL.

I'm not using the OpenGL mode.

All my drivers are current-ish , and using a different soundcard had no effect.

I'm happy at v0.8.21R4, but I'm envious of all these lucky people and their happy flashing LEDs! And the sound filtering is cool, too.

I'll attach my fullscreen config files (generated with v0.8.22R7), and here's my system:

SuperPower SP-P2BXA (440BX)
Intel Pentium III 550@616MHz (Katmai)
256MB PC133 2ns SDRAM
ASUS V6800-AGP (Geforce 256 DDR)
Creative Soundblaster Live! 5.1
Creative AWE64

Win98SE / DirectX 8.1
