New Video Card has Killed Sound

Rommie · 12-27-2008, 11:26 AM

I have just installed a new video card on my PC, it's a Sapphire Radeon HD3450, to replace my old one which blew up a couple of months back. It works fine, but ever since I installed it, I have no sound on my PC. In Device Manager the sound card is still showing as installed and working properly. The speakers still crackle slightly if you turn up the volume, so I assume they are okay, but I don't have any sound at all.

Any ideas?

control panel > sound option.

ATi cards with HDMI capability default their HDMI port as default sound device. You have to change it back.

Check the Bios under integrated devices to make sure the sound is still set to enabled.
We have seen installations of ATI cards make the bios detect the HD sound on the card and switch the integrated off.

Sorry, can you be more specific, how do you check/fix that? I have gone to the sound section in CP (using Vista by the way), clicked on the audio device and clicked properties. Now what am I looking for exactly?

Sorry, I'm a bit newbie at this :)

t would be on playback tab. IT should likely list your origional sound device, and the ATi card.

No, just the sound device. I will try Wrench's suggestion when I get a moment to reboot.

Wrench was right on the money. Went into the BIOS and changed the integrated sound from 'Auto' to 'Enabled' and now magically I have my sound back. Thanks for the help everyone and Wrench especially.

Good to hear you have it working.
