@GhostTheDeadGirl Do you mean the speakers built into your monitor? That's the only sound device your dxdiag lists other than your headphones. So if you have standalone speakers too, the issue is that the system isn't recognizing them.
Anyway, try plugging your monitor into your graphics card rather than into the motherboard as it currently is. Then hit Windows key-i, select Update & Security, click the button to scan for updates, let Windows install whatever it finds, and restart your computer. Please test with the headphones unplugged, not just with the speakers selected as the default output.
While this doesn't seem like it would affect sound, the monitor's speakers are currently (as in, when the dxdiag was run) being controlled by the Intel audio driver, and perhaps the driver doesn't work properly when you're gaming, especially since the Nvidia graphics driver would take over when Sims 4 was launched.
The speakers are not built in to my monitor, they are external. My headphones are Bluetooth wireless and do not plug directly into the PC. The only way to plug my monitor into a different port would be to use an HDMI as opposed to the display port i currently use. No other game is giving me problems and everything else plays through the speakers.
Sims 4 is the only application currently that will not play through the speakers. I believe all my drivers are updated, but will try that and see if it fixes it
