I got a cm300 with no plug in the back to activate internal speaker, does anyone have a pinout for it?

yes it is a cm300, it has no sound at all, could they have disabled it inside?

The speaker may have been unplugged to silence it while using an external speaker. Remove radio housing and look at speaker cable.

Also check to see if it is programmed for handset audio.
