Hi every one,

My HP ProBook 4535s, with AMD Radeon 6480G + 7400M, refuse to play Audio through HDMI port (video pass well but no sound).
I've installed all the latest drivers from the HP website (BIOS, Graphics, Audio...), all the cards have been well installed, except a yellow exclamation point in one of two "High Definition Audio Controller" but I dont have Digital Audio (HDMI) in Control Panel/Sound/Playback (only Speakers).

Any idea to fix that?


I've tried the latest AMD Catalyst, 13.1, but no use
