Hi Charles Lee,
I can see that Q&A Assist and the Independent Advisor have already shared the initial guidance. Please go ahead and try those steps first and see how it goes.
To help narrow this down further, could you please let me know:
- Are you currently using the built‑in speakers or headphones/external speakers?
- Does this happen in all apps, or only specific ones?
In the meantime, while checking the items above, you may also try the following additional steps if you haven’t already:
-Test audio using a different user account on the same device to rule out profile‑specific settings.
- Go to Settings > Accounts > Other users
- Select Add account > Add a user without a Microsoft account
- Create the account, sign out, sign in to the new profile, and test the audio
-If available for your device model, check for any BIOS or firmware updates from the manufacturer’s support site and apply only those officially recommended.
-Try playing audio from different sources (for example, a web browser, a local audio file and a system sound) to see if the behavior is consistent.
Please let me know what you find after trying the steps above and I can advise further based on the results.
