I tried this, too, however, just plugging in the headphones restored the volume control. Having a song playing, headphones in, and removing the dock connector did retain the volume control - for as long as the headphones were in place.
I removed them, and the volume control was gone again.
However, I was trying this while using a Griffin iTrip, and changing the iPod's volume, either before plugging in the iTrip, or while having the headphones in and the iTrip, did nothing to make the volume louder on the FM signal through the iTrip.
Which to me says that the audio out through the dock connector is NOT affected by the iPod's volume setting. It only controls the headphone port volume.
So, I guess, if you don't have something plugged into the headphone port, you don't really NEED to set the volume from within the iPod, and if fact could be misleading to a user to set the volume on the iPod only to find the peripheral to have its own setting too loud or too soft.
It must be Apple's design that devices receving the audio from the dock connector are supposed to control the volume themselves, and the iPod just supplies them a "line level", consisten audio stream. (Sadly, my iTrip does not have a control to boost the volume.)
Is there anyone who can confirm this, either from Apple or who can point to some credible source on the Internet?
hello,
I am having a similar problem but with the timex iControl watch. When i plug in the receiver the ipod tries using it as a speaker and no sound comes out! I spent $150 on it and would like it to work again... And yes it did work pre-3.0!
But I don't even own a dock.. I have touch 3g 8GB.. The only thing I plug on the ipod touch is the 3.5mm jack headset and the USB cable for charging/synchronizing the ipod touch on a laptop.. I wonder what happened, some thread say its a hardware defect, some was fixed thru resetting/ restoring but on my end, got no luck on all of these.
