Blender audio issue

Hello, I’m new to the forums, and because of this reason, my friend and I downloaded a intro for blender for a Youtube channel, I rendered it in avi.raw, but the finished product had no audio, is there a way I can render our intro with audio, and some of the intros have audio in blender that you can hear while others don’t, does this make a difference?

I rendered it in avi.raw
Why did you use this uncompressed video format ? It is used as an intermediate lossless video format for further post processing
It’s video only, no sound Do not use it for a final output.

Use one of the other video formats that are there for your final video outputs.
