I am using a GTX470 with an HDMI output, this card is able to handle the video and audio. I have no issues with the video but I get no sound. Is there a guide to enable sound on this card through hdmi that could be written out or I could be guided to. Thanks!
The only way for the moment to have HDMI Audio support in an Nvidia card is by first installing the proprietary drivers and then selecting the HDMI Audio as output.
Install Proprietary Drivers and Reboot PC
Go to Sound Settings
Make sure that in the Hardware Tab you can see the Nvidia card and then make sure that in the Output Tab you can select the Nvidia card. Select the Nvidia Card as the output and you should hear the sound.
This should be enough to have sound in any of the Nvidia Cards that support HDMI Sound.
I have tested this with:
- Nvidia GeForce GT 440
- Nvidia GeForce GT 220
- Nvidia GeForce GT 9500
- Nvidia GeForce GTX 460
- Nvidia GeForece GTX 560 TI
I also recommend using the Nvidia PPA in this question: How do I install the Nvidia drivers? which I can say has improved my Nvidia card a bit.
Open the sound settings by clicking the volume applet and selecting "Sound Settings". From there, make sure that under the "Hardware" tab, the HDMI card is selected, as well as under the "Output" tab. That should do the trick
