Summary 00130: darkseal: When using your weapon the music playback would ever so slightly increase.
Description When using your weapon (in this example, I used the knight), the speed of the music playback would ever so slightly increase while the weapon was in use and making a sound, returning to normal when the weapon animation/sound had ended.
Steps To Reproduce
Additional Information One of these changes is probably the cause:

0.103u1 changes:
"Many H6280/PCE fixes: [Rob Bohms, Charles MacDonald]
 - fixed cases where sprites could render outside of the buffer
 - added VRAM to VRAM DMA (Charles)
 - multiple h6280 fixes (Charles)
 - provided functions to correctly handle VRAM accesses for the
    entire 128K range (Charles)
 - added some of the I/O buffer bits from the hardware page
 - fixed h6280 IRQ ranges to support proper mirroring
 - hooked up h6280 IRQs to the PC Engine
 - corrected sprite-to-sprite rendering priorities.
 - partially enforce 16 sprite limit"

"Added stream_set_sample_rate() call, and converted the TMS5110,
TMS5220, ES5505/6, BSMT2000, AY8910, POKEY, TIA, Sega PCM/Multi-PCM, SN76496, OKIM6295, and YMZ280B sound cores to output at their native sample rates, allowing the core sound system to perform over/re-sampling to the output rate. [Aaron Giles]"

FYI set Audio CPU% slider down to 23% and this behaviour stops.
