New soundcard, no sound with HDMI from graphics card
by Torkil84 - 6/16/13 9:33 AM
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!
