I think it might be best for you to uncheck the option to restore settings while restoring the backup if that seems to be a persistent issue for you. The problem is that the same configuration file is used on Windows and Android, but the Windows version doesn't support that setting (as you have found). However, there is a little bit of a hack of sorts that you can use. Go to Settings->Backup and Restore->Export Settings on your Android device, and then Settings->Backup and Restore->Import Settings on your Windows device and select the .mcf file that was generated. Now the Windows configuration file will contain your selection for that "Play Audio in Background" setting, and if you backup and restore a .msb file on your Android tablet, it shouldn't change that setting anymore.
