Milan, I think that removing audio group is not a good idea. There are at least 2 reasons.
1. It might affect a lot of system components at least udev, libmtp, alsa which might cause regressions.
2. It would prevent group based access control to the audio device - mind that /dev is dynamic, so configuring back /dev/dsp group owned by audio will not be that easy - i.e. this kind of access control is crucial if your box is used remotely as a juke box.
