Audible Player Question

[stevenmh]

Using the stock Sprint ROM since I got my phone a year ago, I've been able to fire up an audible book, then hit the power button, and the program keeps playing with the phone off, just like WMP will do.

Upgraded to the new OEM ROM from HTC, and now it no longer functions this way. WMP still does, but AP will stop playing when I turn off the phone. Tried installing the newest software, but no change.

Any ideas? I know there's an option to have AP itself turn off the screen after 30 seconds, but having to wait 30 seconds before I can put it in my pocket isn't cool. Nor is having the phone wake up for something and having it skip several chapters ahead. Nor is having to toggle the option when it's in the car cradle and I don't want the screen to blank. Is there a reg edit or something that can be done?
