@FoxWordsmith7 It's not that people are unwilling to help, but that your first post did not provide the required info as described in this link (linked at the top of the forum).
Also, you said you read one post about audio. Have you read the wiki pages? You did not say anything about reviewing the documentation. Most of the answers to questions are there. You can also search for specifics about Pi Zero performance. For example, I searched for just that and found an interesting thread about overclocking to improve NES and SNES performance on a Zero.
The bottom line is that almost nobody on here has the same configuration, and to make matters worse for you, nobody knows anything about your configuration because you have not provided the details. It sounds like you are using a Pi Zero, but we don't know what controllers you have, what version of RetroPie you installed, whether you installed it via the script or loaded an image, what emulator you are using, and so on and so on.
Finally, the Raspberry Pi is a learning platform. Not everything you do on the device will have a "walk through". Some really great videos have been made by the community that can be adequate for some people, but you should assume that if you pursue this you will likely become a technical person when it comes to setting up the Pi, especially if you start tweaking performance with overclocking.
You can find a volume setting both in the RetroPie configuration and in Emulation Station itself by accessing the Main Menu (Start), then Sound Settings.
