Okay, so my problem is:

I recently added a graphics card to my windows 8.1 PC. The card itself works fine (a GTX 750Ti), but since installing it my sound no longer works from either port. Things I have already tried:

• Rebooting (obviously)
• Taking the card out and then replacing it
• Going through all the control panel audio settings (more on this later)
• Disabling the HDMI audio on the card
• Trying different (provably working) speakers and headphones
• Updating/installing drivers (not that you need them for headphones)

The "playback devices" screen declared that nothing whatsoever is plugged in (it is). I'm concerned I might have damaged something during installation, but nothing seems obviously damaged, and I would have expected static to either do no damage or wipe out the entire motherboard. The back port is working, so it isn't the cable. My monitor output is HDMI (with no speakers on the monitor), if that makes any difference.

Penny for anyone's thoughts?

Have you tried taking the card out and booting either your old card or onboard video to see if the card itself is causing the problem?

EDIT: You might also want to check and see if sound card audio drivers were installed and uninstall them. Even though you disabled the HDMI sound on the card the drivers may be interfering. You should also check to make sure your onboard audio hasn't been disabled.

Hi,

In my opinion, you issue is more related to the graphics card driver, it's better to get the new driver applied to your graphics card and OS model.
