Enthusiast, ispalten & hatryst,
Sorry for late reply ~ life (and a teenager) ~ intervened.
Thank you for the suggestions, but yes, I tried them all MULTIPLE times and still have same problem. Switched mute and lock rotation back and forth, did hard reset, ...even did vacuum trick some people had luck with & nothing.
I get full sound when dock is plugged in, and with a flashlight and frustrating contortions, I can see the little metal (?) pins (?), which I tried cleaning with a toothpick wrapped in a coffee filter (...it's driving me nuts having to cart speaker dock around).
The ABILITY to produce sound is there: after full/hard reset, i get the 'slide to power on' click. That's it.
I'm going to update my OS, so that remains a dim possibility.
Honestly, I think my sound is just done for.
...so much so that I think a heads up to be careful choosing/using these dock stands is necessary ~ not only is there a ton of folks online, I came across TWO real-life "me too!"'s while b***ng at work. Hopefully there's a fix we're all missing, but....?
In case anyone's interested, the dock that ended my iPad audio was the iHome from walmart. The two others I found also bought their docks from Walmart, & I *believe* it's same model, combo speaker & stand.
Before iHome sues me, I DON'T KNOW IF FAULT WAS DOCK! ...only that I had sound, tried my new dock out, then never had it again.
