Ed, thanks for the feedback. I will say that requiring "stop" to be pressed while in the middle of a long playback seems counter-intuitive. I'm sure regular (non-programmers) are going to be bitten by this a lot. That's why I'm reporting it. When the cover is on, the machine should really go do sleep. Perhaps a d-bus event should be sent (if not already) that says "hey, we're really going to sleep for a long time here", and applications that use the DSP can properly save register state and put it to sleep. Why doesn't the OS tell the DSP to suspend itself? If it currently does, but it still draws a lot of power because state has to be retained, then applications should be redesigned so they do such a shutdown. I think there is a difference between "idle sleep" and putting the cover on. -- Brad Clements, bkc at murkworks.com (315)268-1000 http://www.murkworks.com AOL-IM or SKYPE: BKClements
