No sound after Graphics Card installation

[kodyparker]

It appears that I have no sound after upgrading my Graphics card from an AMD to a Nvidia GTX 760. There is no option on bios to disable onboard high def audio, and Realtek will not install back onto my computer? Any help would be appreciated.

I had a similar situation after the recent update from Gforce Experience (Sept/2016) - ended up - UNINSTALLING the sound driver from Nvdia - and *knocking on head twice* appears to have corrected issue - the video driver is unaffected by this action.

I too encountered a similar problem when I upgraded my Dell Precision T7400's 256MB NVIDIA Quadro FX570 card to an EVGA 2GB (GDDR5) GeForceGT730 card. After deleting the old card's drivers, installing the new card and its corresponding drivers, my computer had switched to HDMI audio and the onboard audio wasn't even showing up in the sound control panels as a selectable option. Checking for updates, allowing Windows to attempt to repair the problem, and reinstalling RealTek's audio drivers didn't remedy the lack of sound. What did work (as mentioned previously) was adjusting a BIOS setting. On this particular computer, pressing F2 during startup opens up the BIOS settings menus. Using the arrow keys, I navigated down to "Onboard Devices" and from the sub-menu selected "Integrated Audio". There are three settings from which to choose from. This computer's default setting is "Auto". The other two settings are "On" and "Off". Apparently, my new card's ability to use HDMI causes the "Auto" selection to default to HDMI. Since I'm using an analog audio jack connected to external Logitech speakers, I need the computer's onboard audio enabled. Switching the Integrated Audio from "Auto" to "On" bypasses the whole auto-detection snafu, and will allow one's computer to boot up and detect devices plugged into its on board analog ports. Just be sure to save the new setting when exiting BIOS. All is good now.

That is the problem I just hit last night when I swapped in a Radeon to serve my wife's HP Vista desktop with a broken VGA connector from the onboard Nvidia graphics.

For the whole night I thought there were conflicts between the drivers. This morning when I checked the BIOS the 3rd time, I finally found an onboard sound option. It was set to Auto. When the graphic preference is set to onboard, the speakers work. When the graphic preference is set to PCI-E, the onboard sound disappears completely from the device manager. Sound would come out from the TV, but no mic for skype.

Setting onboard sound option to on, fixes the issue. Then I have sound devices from both onboard and Radeon (HDMI) when the graphic preference is set to PCI-E. I got my mic back. I wasted a dollar though, in ordering an USB sound card online when I could not get it to work late late last night.

Check if other devices (like mic, line in under recording) still exist. If not, It is likely the BIOS.

Good luck.

Running Windows 10 Home 64-bit
Ran the latest nvidia drivers released on 21 September 2016
Lost sound after installing
---
Right clicked sound icon in the task bar, my play back default had changed to my Monitor(go figure?) which doesnt have sound. Changed it back to my speakers, working once again.

simple fix, but rather stupid for the nvidia drivers to change that setting on its own.

I had the same problem:
Real Tek Audio Drivers which come with a Gigabit MOBO
Installed brand new EVGA GTX 960 2gb with latest drivers

This thread gave me the hint about Nvidia taking the HDMI card sound as the MAIN. The problem was that at the regular control panel there is no way for me to revert again over other sound inputs (front audio jack, etc.).
So I went to the Real Tek "Admnistration Tool" which cames by default with this MOBO (see image here: http://imgur.com/a/3s1Z5 ) and I saw there is a function that reads: "Advanced Device Configuration", when you click it it has 4 options, the one you want is the one which reads (excuse my poor translation): "Make the front and back output devices reproduce two different audio sequences at the same time".
So that made the sound come back 100% for me. n
My sound devices look like this: http://imgur.com/a/AkKHg (I have DFX software for improving some aspects of the sound quality to your taste, that's why it is also ticked as green). Before making this change the legend of the Real Tek output was not "2nd output" but now seems that Nvidia has relegated it to a 2nd place lol!

Hope someone find this helpful because I'm to grateful to this forum because it has helped me with really tough decisions and serious issues.
