Ok, when I connect my HP DV6 laptop to my Samsung TV the picture works fine but the sound comes through on the laptop only, not the TV.
The problem is that I don't seem to have the driver
for HDMI audio output, see the below picture:
Now, a friend came over today and he has a Dell laptop with EXACTLY the same graphics card (ATI HD 4570), he used the HDMI cable with my TV and the sound comes through fine.
I looked at his playback devices and he had an extra sound driver called "ATI High Definition Audio Device". I do not have such device. I do not have this device after downloading and installing the same "Catalyst Control Center" again and again and again and again. I am tired of seeing this damn control center as it never installs the driver I need.
I just need one, one measley driver to have sound and ATI has completely failed me at this, their control centre regularly crashes when I try and install it and my display sometimes crashes too.
