iPod Touch will charge but won't play when connected to a Sony docking system I bought a Sony ICF-CS15iP docking system and my iPod will charge when I connect it, but it will not play music through the speakers. This is my 3rd docking system and I have had the same problem with the others - it will charge but not play.  I'm assuming it is my iPod that has something wrong with it. Should I call Sony and or Apple?? Thanks!
Note* I have a 4th gen iPod Touch
I found a product description on the Best Buy website: 


  The ICF-CS15IP is Compatible with most iPod® and iPhone® models, including iPhone 4. Works with: iPod touch® 2nd, 3rd, &amp; 4th generations, iPod nano® 3rd (video), 4th (video), 5th (video camera), &amp; 6th generations, iPod classic®, iPhone® 4, iPhone 3GS, and iPhone 3G.


Your 4th generation iPod Touch is listed as supported by this device, so you should contact Sony and expect them to help you.
