reinstall dolby audio driver
I just upgraded from 8.1 to 10. Since then I get the message logging in that Windows cannot open dolby audio and to reinstall. Sound is barely audible thugh it was fine with Windows 8.1 found one on Wndows driver download page but, though I got notice it downloaded successfully, the problem persists - i.e. message doby failed to open - and sound is still barely audible. Any help greatly appreciated. At 75, I'm hard of hearing despite $6,000 pent on hearing aids.
