Yeah, not exactly a satisfactory one, though. Just something along the lines of "We have sent your request to remove DRM to our audio team. We value your feedback." It was a nice way of saying that mail has been forwarded to the audio team to throw in the bin. Still, better than being ignored outright.
Demand a refund. My girlfriend ran into this problem (we're pretty much a Linux household). Just could not get the audible books to run on Ubuntu and I wasn't willing to spend the time hunting around for a way to get around it. Fortunately, Audible was pretty gracious about the refund.
