Hi,
the Version of my drivers are:
intel Display Audio: 6.16.0.3129 (16.10.2013)
Intel HD Graphics 4600: 10.18.10.3345 (31.10.2013)
All Drivers installed from zip-File in the Device Manager.
After Reboot: Sound works
Change HDMI Source on TV: PC -> Blueray -> PC: Sound works
Power off TV -> Power on TV: sound is lost, cannot reactivate until reboot.
One question: How can I upload Files in this editor, there is no icon for Upload only "insert link"
