Issue with sound on portable dvd player

[Lumacosy]

With my project, I'd like to be able to do as much as I can without taking anything apart, because I don't know how to do it, and I'm afraid to mess up. My issue is I'm using the AV in port on this portable dvd player to transfer the Audio and Video from the Raspberry Pi to it. However, the only way it will transfer video is if the Yellow and White cords are switched around. It will show the video, but it emits a buzzing noise if the volume is turned up. Would there be any way to keep the setup as close as possible to what I have now whilst fixing the audio? Thanks.

Do you have the correct AV Cable for the RPi, which I presume has the TRRS Connector, as you have not stated RPi model:

I am using a Raspberry Pi 3 model B, and my wire looks identical to the one shown in the photo (although I don't know much about the technicalitys of it all).
