Microphone issues with OSS

My microphone likes to output itself through the speakers and I don't know how to stop it.

I saw this in the wiki but....

Microphone playing through output channels

OSS by default plays back the microphone through the speakers. To disable this in ossxmix find the misc section. Check off every "input-mix-mute" to disable this.

There are no such options.

I'd take a screenshot of my ossxmix window but it is too large to fit in one screencap.
