Check if this happens after KB5124008 update from windows history. If Yes, then The KB5124008 update fixes a large number of vulnerabilities, including actively exploited zero‑days. Uninstalling it significantly reduces your security posture, so you should only uninstall it if File History, audio (or other critical features) doesn't work and you need them.

Hi. I'm David, and I'm happy to help you.

To be able to assist you better, please clarify the following:

• Are you trying to play audio via internal speakers, external speakers, or headphones?
• If it is an external speaker or headphones, does it have a standard audio connector (Jack connector) or a USB connector, or is it connected via Bluetooth?

Also, share a screenshot of your system information.

• Press "Windows + R", type msinfo32 and press Enter.

Maximize the window and use the shortcut "Windows + Shift + S" to use the screenshot tool.

Looking forward to your reply.
