Unable to connect to non blue tooth speakers
I used to be able to connect my iphone/ipad to a non-blue tooth receiver using an adapter, charging cord, and usb connection. This week I noticed that the iphone/ipads don't recognize the setup, but still recognize a headphone/earphone. I verified everything works separately, but not together to do what I want. I am assuming this is some sort of setting issue, but can't find the settings. Thanks for any advice.
