At the moment most of the time screen blanking (and subsequent standby) doesn't often work for me as I usually leave a visual like swarm on, so the screen is always changing. Therefore it would be good if HiJack also had the ability to blank the screen and put the unit into standby after a certain period of audio inactivity.

The VolAdj feature is already looking at and fiddling with the volume of the out-going signal all the time, so adding code to keep track of wheter the out-going signal is changing should not be much of an over head.

This feature could only operate when the player was in MP3 mode, otherwise it would always get triggered after the defined period in tuner or aux mode.
