Hello, As the topic says, my computer doesn't detect my on-board sound card. It all started when I tried to install new audio drivers from manufacturers page, but the next day when I booted PC up there were no sound. In Device Manager, under Sounds, game,.. controllers tab sit 4-5 High Definition Audio Devices. Here's pic: Then tried re-installing original audio drivers from motherboard CD, enabling/disabling On-Board HD Audio in BIOS but still no luck. My Audio Device is VIA VT1705. DxDiag shows that no sound card was found. This is what is shown in Playback Devices tab: But I have no HDMI kind audio devices.. How to make my system recognize my sound card?
