Summary Regresssion 09401: SDL sound unaffected by fast forward
Description sdl is the default sound output method, if you press the fast forward button the video accelerates but the audio doesn't. So, after a while, you get a video-audio delay.
It doesn't happen with the other sound output methods; portaudio, pulse and pipewire are not affected.
It never happened before, so I guess the new upgrade from SDL2 to SDL3 is involved.
Steps To Reproduce - Start any game with the sdl sound output method (the default):
mame tehkanwc -sound sdl
- Press the fast forward button (Insert for Windows non-SDL MAME or Page Down for SDL MAME) for a couple of seconds.
- You'll see the video accelerate, but the audio will not.

I don't use SDL so unable to confirm, but it's acknowledged. Hopefully someone who does use SDL can check it out.
