If your Elgato Game Capture HD audio plays in the software, but not on the passthrough TV, then some aspect of your Settings or Setup are probably incorrect.
Please try the following steps to see if they help with this issue:
1) Your TV may be set to the wrong volume.
Solution: Check your TV to make sure that it is set to use the right volume level, and is not muted.
2) Make sure that you're using a HDMI cable with your TV or Display, and not a HDMI to DVI adapter cable.
Solution: DVI connections are video only - audio will not be transmitted. Use an HDMI cable connected to your TV, so that audio and video can be transmitted.
3) The Elgato Gaming hardware may need to be reset.
Solution: Unplug the Elgato Gaming hardware from the Mac or PC, and video source. Wait a minute, and then attach everything again.
4) The Elgato Game Capture HD software may need to be reset.
Solution: Quit the Elgato Game Capture HD software, and then launch it again.
5) The HDMI cable may be defective.
Solution: Test the HDMI cable with another video/audio source (without using the Elgato Gaming hardware), to make sure that the volume is working properly with your TV.
If another video source also doesn't output any audio to your TV, then you may need to replace that HDMI cable.
If none of these steps help, then please contact Elgato Technical Support for further troubleshooting.
