概 要BGFXを使うとAudio Syncが動作しない。
詳 細Audio Sync is an feature that avoid crackled further in sound. Very good feature.
Possibly MAME was the first emulator to use an feature that sync the sound and video.
Others emulators also has that same feature called with other name being Time Stretching.
Audio Sync was added in MAME in several versions before 2011.
After some versions Audio Sync configuration was removed and enabled internally for good also as was resamplefilter.
Since when BGFX was added in MAME the Audio Sync never worked.

Audio Sync to work need enable refreshspeed.
To test enable OSD slider and refreshspeed.
If Audio Sync is working adjusting refresh rate for a higher value the sound will be slower.

Start any game using D3D output. Rygar and SF2H are good examples.
In OSD select screen refresh rate and adjust for a value above of 60 HZ.
The sound will be slower showing that Audio Sync is working.

Now start any game using BGFX output and adjust screen refresh rate for a value above of 60 HZ.
The sound is not slow meaning that Audio Sync not is working.
