Dell Inspiron Audio issue

Hello Dell support team,Jimco,

I am facing some problems with Audio in my Dell inspiron 5559 only after updating to Windows 10 AU. Audio is not working after turning ON pc. But It will work fine after restarting PC.So every day I have to restart my PC before doing any work in it.Drivers are up to date(Realtek) and installed Dell update utility too. I tried audio trouble shooter from control panel also but its just doing nothing.Could you please suggest me any  possible ways to rectify it.
