Dear Tariq Siddiqui1
Thank you for posting in the Microsoft community.
1.Firstly it is recommended that you check the manual section of your monitor to see if there are on-screen buttons to raise or lower the volume.
- Right click on the sound icon at the bottom right corner of the screen - Sound Settings - More Sound Settings at the bottom - Playback - Find the model of your monitor - Double click on the left mouse button - Enhancements - Disable all enhancements - Spatial Sound - Turn off spatial sound.
3.HDMI sound control and graphics card driver also has a relationship, if you are using the nvdia graphics card driver, you can re-download the NVDIA graphics card driver - install the sound card driver module.
Good luck.
I hope the above information helps.
Best Wish
