RealTel HD Audio Manager Help . in Computer + Tech Posted June 3, 2010 Okay So I Was Editing Files In Aduacity And I Had Wanted To Make The Audio Louder So I Brought Up Realtek HD Audio Manager . I Really Don't Mess With Computers That Much , But I Pretty Sure I Did Something Bad . Cause From That Point On I Can Hear NOTHING From My Computer . I Even Tried Plugging In Earphones But I Still Can Not Hear Nothing . When I Bring Up Digital Output , There Is A Checkmark And I Before It Was Never There . On The Speakers Out Put There Is A Bar That You Can Select: Select Default Device, And Select Communication Device . On Digital Output I'm Not Able To Click On The Bar . And I Think That Is The Problem . So Can Anyone Help Me With This Please , Cause It Is Starting To Get On My Nerves Not Hearing Anything ! Thanks In Return unless you're using HD sound output (through either HDMI, optical, or coax) the sound will be analog output. dont try and change it. there should be a option to change it back, if not you have two options 1. uninstall and reinstall sound drivers (99.99% should work) 2. system restore (MIGHT work) so its realtek hd obviously (its very common) but you need to find the exact model number, check Device Manager (run-> devmgmt.msc) Thanks That Helped Alot! And If A Mishap Like This Happens Again I'll Remeber To Come Back To This Useful Resource . Again Thanks Both Of Ya'll For The Help !
