You could previously control volume from the Touch when docked to a speaker dock, but now it's all up to the device you're docked to.
On a 1st gen touch it can tell if no headphones are connected, and since there is no internal speaker you won't get a volume slider. Plug in headphones and the slider will appear.

i don't get why it says dock connector when no earphones are plugged in
It apparently has nothing to do with internal speakers. I have a 2G Touch, and when I have the FM transmitter plugged in, the volume control - which was there last week - is now gone. And no, the side controls don't work, either. Now I HAVE to use just the stereo's volume controls. It's not a big deal, but I kind of liked the ability to control the volume from the Touch.
The reason it did that was because you plugged in the FM transmitter. My brother has a second generation iPod touch and when nothing is connected (unlike my first generation) the volume control remains.
