How to get audio through HDMI port of Graphics card?


I have recently upgraded my graphics card of my Desktop PC to MSI R5770 Hawk with HDMI port. I have also Asus Xonar Essence (2.0 channel) audio card already installed in my PC.

After installing the graphics card, when I connected my Panasonic 42V20D plasma through the gfx card's HDMI port, the video signal is received but without any audio.

Somehow, I managed by connecting the 2.0 channel audio card analogue out to my Marantz AVR and listened audio through it.

Can anybody help me in making understand me how I can send the audio also through graphics card HDMI out port?

Try right clicking the sound icon in the system tray, selecting the 'Playback Devices' and setting the HDMI out as default rather than the Xonar output.

Your sound card needs to have a spdif out header & also your graphics card should have spdif in header. This way you can connect a 2 pin cable from sound card to graphics card. Then you can select the audio to spdif & the audio+video signals will be sent from your pc to to your avr/tv

If your sound card doesnot have the spdif out header, check if your mother board has it. In any case your graphics card must have spdif in.

I think the series from Radeon 5xxx upwards can directly bitstream upto 8 channel audio via HDMI without any sort of spdif ins like u mentioned bro....i might be wrong though.

hi,

in that case the graphics card should have an inbuilt soundcard & it can be eanbled by installing the hdmi audio driver of the graphics card. I have a old xfx nvidia 9400gt & asus board & i have done a physical connection as mentioned above & the audio+video is sent to my lcd tv.

Re: How to get audio through HDMI port of Graphics card?

Inrahn, I am getting both audio and video now through HDMI, which is connected from my PC to my Marantz AVR. My Panasonic Plasma is connected with AVR through another HDMI cable.

But, when I am trying to listen only music through my AVR (keeping my Plasma off), the sound is not coming through Computer graphics card HDMI. But as soon as the Plasma is swiched on, the AVR receives audio.

Any clue, how to resolve this problem?
