Question

New soundcard, no sound with HDMI from graphics card

by Torkil84 / June 16, 2013 2:33 AM PDT

Hi,

The internal sound card on my Windows Vista PC broke a few days ago (I concluded that it broke after having tried reinstalling all drivers etc. etc.). I have now purchased a new sound card (Xonar DGX). The sound card works fine (for example, when I plug in speakers directly to it). However, my graphics card (ATI Radeon HD 4350 512MB2, which I use two of its HDMI ports to output to my monitor and TV) does not transfer sound along with the video signal.

I have de-activated the "internal sound" in BIOS settings and I have chosen the correct sound option in the sound manager (for example, the "Sharp HDMI"-option when I want to play video/sound on my TV) but still no sound. No conflicts etc. in device manager.

Does anyone know what the issue could be? I am desperate now as I have been troubleshooting this all weekend...

Thankful for all the help I can get!

/Fredrik

Hi, thanks for your reply but I do not see that post/discussion
containing an answer to the question. Do you perhaps have a link to one
that does, out of those thousands of posts?

Thanks. /Fredrik

I didn't propose a fix.

I asked why you thought a sound card was needed for HDMI audio. As to the thousands of prior discussions you can use google or such. But once in a while a member gets upset about a reference to prior discussions.

Here I wanted to know why you thought any sound card is required for HDMI audio. You may have been misdirected by a prior discussion and installed a lot of drivers that have upset this OS and system.

That's how it works

That's how it works and if you want audio from the sound card over HDMI, you need an internal SPDIF cable to connect the sound card and video card.
