ATI HDMI audio not working. It is set as default device but it is still not working. I am using windows 7 with radeon 3200 onboard graphics and I am connecting it to my samsung lcd tv.
It gives an error that the audio device you selected is currently turned off in windows.
Please help.

Are the drivers updated to the latest ones?

Also disable the audio to your speakers on your computer and make the LCD the primary display.

Disconnect the cable from the PC when the power is on both the tv and PC wait 10 seconds ad plug it back in

I dealt with the same issue last night, and got it fixed. I new that it wasn't a card, TV, or cable issue because the machine dual boots to Server 2008 and the HDMI audio on that install worked perfectly. I tried many other strategies until I realized that the HDMI audio driver wasn't being updated when I downloaded the new drivers from ATI. I discovered this after I uninstalled the ATI drivers and realized that the audio device was still listed in the Device Manager as ATI. Using Device Manager I uninstalled the device, but it reinstalled itself a few moments later. So, I looked at its properties and found the name of the driver "AtiHtmi.sys". I did a search and found the file in two places:

C:\Windows\System32\
C:\Windows\System32\DriverStore\FileRepository\[ati subfolder name]

If I deleted the file from just the System32 folder the system healed itself by copying it from the FileRepository's subfolder. The FileRepository is a system folder, but if you are an admin and can take ownership of it's subfolder that contains the driver, you might be able to delete the backup driver's containing folder. I dual booted with Server 2008, so it was a bit easier for me.

Long story short--I uninstalled the ATI drivers, deleted the remaining ATI HDMI Audio drivers, rebooted, then installed the latest ATI drivers and it worked.

I hope this helps somebody else, too.
