No Audio Playback

Hello, I have started using Davinci Resolve today, but I'm facing an issue with the playback audio. When I play any video from the timeline or from the media tap there's no audio. The audio mixer shows that the audio is playing while it's not. I have tried reinstalling Davinci Resolve and reinstalling my audio drivers, along with every single other solution I found online, with no success. That included every setting in the (Video and Audio I/O) tap in the preferences. Also, adjusting many windows audio settings.
I should note that I'm sure my PC, audio hardware and drivers, are all fine, and Davinci Resolve is the only program that I'm having sound issues with. All of my specs are listed below.
Hope someone can help me. Thanks!
