Raspberry Pi Sound issue only when playing Vertical Games

[hypergaming]

Hi everyone,

I recently put together this Raspberry Pi 2 Player control panel, but I'm having some audio issues. Horizontal games play perfect, but there is a sound issue only with vertical games such as Donkey Kong, Moon Cresta, etc. I tried a bunch of them already, and they all have the same sound issue.

Has anyone ever experience audio issues only when playing Vertical Games?

here is a video link, listen carefully to the noise that comes out, and like I said, is on all the vertical games, not just Donkey Kong, so its not a rom issue.



I'm using a Raspberry Pi 2 Model B - Emulation station / Retropie ( not sure which version but is not the latest one )

I appreciate your help!
