概 要refreshspeedを指定するとひどいノイズ音が発生する。
詳 細I have noticed for a while that refreshspeed in combination with another switch [perhaps?] can cause terrible static/screeching sound output in games that utilise it [calspeed, pacman, dkong] fullscreen or windowed. But couldn't find the right combo to repro it.

I was able to repro it w/ a baseline 32bit Mame.exe and running calspeed using the attached ini's settings. I also thought this may have been a MameUI multisession issue but the baseline produces it too straight out of the box. I can hear it sometimes when pacman or dkong are the second games played in MameUI or in a multi-session Mame.exe 'start new game' if that's any hint to the fix.
再現手順Use the enclosed ini, launch 'mame.exe calspeed'

1. Hit F11 to bring up OSD.
2. Let the demo mode play.
3. Sometimes the horrible sound will exhibit immediately as the cars come down the California valley, sometimes it takes till the flyover for the start of the demo race.
追加情報This doesn't appear to be x86 specific as I have repro'ed it in x64 as well.

Note: This isn't a case of the system too slow to handle it/stuttering. Game was cranking at 99% which is what it should be using refreshspeed on a Core2Duo at 3.5Ghz 64bit Vista.

60Hz LCD + Triple buffering, thus the need for refreshspeed.
