I'm running the latest version of CM and am really enjoying it. I have, however, been having issues with the volume control of the device. Basically, I hit the volume button to change the notification volume and it does nothing. At this point, there is no volume so I can't hear any notifications. If I press the volume down button, the vibrate function will activate but that's all. Going in to the sound settings menu didn't work either. It let me move the slider, but as soon I close out of that menu, the volume goes back to nothing. One additional issue I've had is that calls start by default in speakerphone mode. Luckily, it lets me disable that but it's mildly annoying.
Anyone had these issues? I apologize if these issues have already been covered a million times. The CM7 thread is just daunting, though!
