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.

Windows 7 Ultimate 64bit

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!
