Hi Sathish Kumar,
Thanks for reaching out to Microsoft Q&A Forum. I understand that your laptop speakers are not working properly even after updating settings.
Please make sure you already tried the Q&A Assist steps. In addition, please try the following.
To help narrow this down a bit:
- Are you currently using Windows 10 or Windows 11, and does the issue occur after a recent update or restart?
- Do external headphones or speakers work normally when connected to the same laptop?
In the meantime, you can try these steps:
1, Restart Windows Audio services
- Press Win + R, type
services.msc, and press Enter - Restart Windows Audio
- Restart Windows Audio Endpoint Builder
2, Set the default playback device manually
- Open Control Panel
- Select Sound
- Under the Playback tab, right‑click your laptop speakers
- Select Set as Default and then select OK
3, Check speaker balance levels
- In the Sound window, select your speaker device
- Select Properties and open the Levels tab
- Select Balance and make sure both left and right channels are set equally
4, Roll back the audio driver (if recently updated)
- Open Device Manager
- Expand Sound, video and game controllers
- Right‑click the audio device and select Properties
- Under the Driver tab, select Roll Back Driver if available
5, Check BIOS or UEFI audio settings
- Restart the device and enter BIOS or UEFI setup
- Make sure onboard or integrated audio is enabled
- Save changes and restart Windows
6, Create a new local test account
- Open Settings
- Go to Accounts and then Other users
- Create a new local user account
- Sign in with the new account and test the speaker behavior
