Hi Everyone.              Im having a problem with my LENOVO  ideapad z580. Last night when in unplugged my headphones, there was no more sound coming out from the speakers. Any suggestion on this ? i reinstalled the realtek drivers , checked all the sound definitions (none were hidden) .

When I tried to open the device manager there I found that -  " other devices ? BCM 20702A0 " .    It did not respond to update the drives.  When I tried to check with a driver updater, it was prompting the relative drivers are missing.  Any help would be appreciated to DOWNLOAD the required driver PLEASE.
