Onboard HDMI output of Gigabyte ga-a75m-ud2h has stopped working

Recently I have assembled computer with Gigabyte ga-a75m-ud2h motherboard and it has started giving me problem with HDMI port. Now whenever I connect my LCD TV with my PC though HFDMI cable at that time I cannot get audio. Please tell me what should I do to solve this problem.

You have to first check which version of the HDMI cable you are using? According to me you should use HDMI cable 1.4. if you are using HDMI 1.4 and then also this problem is occurring then I will suggest you to try different HDMI cable and then see whether it makes any difference or not. I am telling you this because many times because of faulty cable also this type of problem takes place. You have to also check in your sound setting whether correct playback device is selected or not.

Try this solution and then let me know what the result is.

Did you try to solve this problem by updating the drivers or reinstalling the drivers? If you have not tried then I will suggest you to first uninstall the drivers from your computer completely and then you have to reinstall the drivers and after that check whether it makes any difference or not? you have to also check on official site of Gigabyte whether there are new drivers are available for Gigabyte ga-a75m-ud2h motherboard or not. if there is new drivers available then you have to download that drivers and update it. Now after that your problem might get solved.

You should try to fix this problem by connecting on-board video with graphic card with the help of SPDIF cable and then check whether you are able to get audio though HDMI or not. I hope this solution will be helpful for you or not.
