Choppy audio when minimizing videos at 60fps

Choppy audio when minimizing videos to 60fps... windowed, maximized or fullscreen works normally...

Try set Flip mode for EVR CP
Try reset settings..

@Aleksoid1978 I just found the origin of the problem...when VSync is enabled (Enable Vsync via Direct3D9) the problem occurs when playing minimized videos at 60 fps...

@Aleksoid1978 With Flip/FlipEX Mode for EVR CP the problem is not displayed when VSync is enabled...but shouldn't this option be enabled by default instead of the other or what is causing this problem? Why does this only happen with minimized 60 fps videos?

[Aleksoid1978]

Flip can work bad on old hadrware/drivers.

Why is the video renderer affecting the audio?

Perhaps renderer could simply drop all frames when player is minimized? That could potentially save energy for processing stuff that isn't shown anyway.

@Aleksoid1978 I was doing some tests and the Flip mode gives me other problems, for example: when opening a video downloaded from emule from the same program (eMule) the video is displayed in a small window in the upper corner or simply the screen goes black (Launch Files in Fullscreen)... the same happens when using the MPC renderer...I have chosen to use the MPC renderer and Swap Effect in Discard...
