Doh! Resolution = Audio Enabled

From the nvidea control panel, go to the change resolution screen. There you can pick if audio is enabled or disabled. Go figure.

it appears that simply momentarily starting nvsvc is enough to refresh the playback devices list.

What I don't get is why there appears to be so many unplugged devices!

I have two 3.5 mm jacks. One says S/P Dif. Is this another crazy hybrid port, allowing for "normal analog"(3.5mmjack) AND digitalaudio (again, via 3.5mm)?

Windows 7 Ultimate x64

I had the same problem: ATI HDMI audio not working (i.e. when I connected the HDTV to the laptop via HDMI cable, even though I connected with video I wasn't doing it with audio). I was running a Dell Studio 1749 with Windows 7 64-bit and ATI video card. After reading the forums, I finally found the solution to the problem (hope it works for you as well): I was missing was an audio codec from Realtek (which I did not have installed). Go to this link is to the Realtek website where they have their HD audio codecs:


Install the ATI HDMI Audio Device codec (I installed v R2.7, file name HDMI_R270), restart computer, and after you connect your laptop to the TV via HDMI cable, right click the Sound icon on the lower left of the screen/desktop, select Playback devices, set Realtek HDMI Output as default and now your sound should get out on the TV. Good luck!
