Squeaky audio with WinUAE
After firing up WinUAE after a while and loading in an old Legend save I noticed that the audio would squeak/distort every few seconds. After trying a number of suggestions from places with nothing making any difference (sound buffer size, interpolation, audio filter, sound driver, along with a number of display settings) I noticed an option under
CPU and FPU titled
CPU Emulation Speed. Default setting was
Fastest possible, toggling this to
Approcimate A500/A1200 or cycle-exact fixed the audio problems and also dropped CPU usage from being pegged at 100% to <10%.
