Post a screenshot of your device manager.
of course i can hear the sound, when i use lg flash tool it ggoes but doesn't complete. And with lg air drive, it ask keeps on asking me to install mtp lge drivers. i think i can find this drivers on another lg phone by selecting usb connection type on MTP so that the drivers can be installed automatically.
