(I have not modified my 7022) ... playing mp3s or netflix (or any app with sound) I get popping, crackling sound while display is on. If I turn off display (put into standby mode) my music app will still play, and the popping and crackling artifacts go away. BTW, my earbuds are $40 JVC and work fine in other devices. Can anyone else confirm they have this problem with their 7022, please? I would like to keep my 7022 (return it for a new one), but if this is a issue with all of them I'm going to return it and get something else. Thanks!
