Hello i have a olympus fe-210 and the volume doesn't work fore videos

I have the same camera that my parents bought me for my birthday this year. I noticed that there was no audio for videos so I looked around to see if you could turn it on in settings. I noticed that there was a silent mode option so I turned that off. I tried to do a video again and there still was no audio. So I looked around and pressed so many buttons until i found the volume option (I don't remember how I got there I'm still trying to figure out again) I turned the volume all the way down because I was concerned about the beeping of the camera. But then after I found out that you could turn off the beep, I tryed to look for the volume button, and I couldn't find it. I was wondering if anyone knows how to get back to that volume button.

This camera does not have a Mic.
