Hi,
Have you tried checking if your sound settings is all correct?
- Right click on the speaker icon then select Playback Devices.
- if your speaker is listed right click on it and select Set Default.
- Click Apply and OK then test it again.
- Test your laptop with your speaker again and see if it will work or not.
- If it doesn't work do uninstall/reinstall the sound card driver.
- Go to Device Manager and uninstall the sound driver.
- Next is to download and install the latest driver from the manufacturer site.
- Once installed reboot your laptop again then test it after the reboot.
