Hello, @Rmm11
May I ask which motherboard you are currently using?
Is the lack of audio related to connecting the screen via DP cable, and have you tried cross-testing with different DP cables or devices?
Could you please provide more details, such as hardware specifications, BIOS, and driver versions, for us to better understand your situation?
For potential related FAQs, you can refer to [Windows 11/10] Troubleshooting - Sound (Speakers/Microphones) problems.
Thank you.
