But here, I have this HTPC with the onboard sound disabled, no other sound card and HDMI sound works fine. How can that be?
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!
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.
