I notice this a couple of days ago, and at that time I didn't realize N900 behaved differently after the re-flash. But for me I view it as a feature but not a bug since what happened mirrors what I see on PC.... the media player volume is separated from the OS volume. That way I can adjust the volume more finely. There might be noise/distortion creeping in if your setting is off, but it's no big deal to me so I vote for this feature to stay!
