I have owned and enjoyed the Bose SoundDock speakers for a number of years; during this time it has worked great with my iPod Mini, Video iPod, and iPod Touch. The speakers have an iPod dock that you seat the iPod in and the audio is played through the speaker.
These speakers predate the iPod Touch by many years and won't recharge the iPod Touch when plugged in. That's fine, I mention it because whenever I plug in the iPod Touch into the speakers the iPod Touch shows a message that recharging isn't supported.
Recently, when I dock my iPod Touch in the speakers the warning that it can't recharge comes up, but no sound is played through the speakers. Instead, the iPod Touch's existing speakers play the music. Plugging in my Video iPod still works as expected - the sound comes out of the Bose speakers.
I've tried undocking and redocking, wiggling it once docked, and so on, but I am unable to get the iPod Touch to play through the Bose speakers. Any idea what's going on here? This is frustrating since I use these speakers quite often...
EDIT: Some further clarifications. My iPod Touch is a 2nd-gen iPod Touch (if that matters). It is, and has for some time, running software version 4.1. I have not tried updating to 4.2 or restoring the iPod's original settings. Also, the speakers continue to work with my iPod Video, so I'm pretty certain the problem lies somewhere with the iPod Touch and not the speakers themselves.
