After I installed the latest update of AMD Catalyst Control Center, I can no longer hear the sound of my television, connected to the desktop via HDMI.
The old and working version is 14.12 AMD Catalyst Omega Software.After restored the system to its previous state, everything is working properly (even the sound of my tv )
SO is Windows 7 Ultimate -64 bit

In my case the HDMI drivers are not installed and I have this error in the device manager, I hope the next drivers settle it. I am currently with 15.7 drivers, will try to 14.12. Thank you.
