Hi,
Method 1:
If the issue persists I would also suggest you to start the Audio service and set it to Automatic:
a. Go to the Start screen.
b. Type “Services.msc” without quotes and press Enter.
c. Right click on Audioservice and click on Properties.
d. Set the Startup type as Automatic and then click Startunder Service status.
e. Click on OK.
Method 2:
If the issue persists, I suggest you to set the speaker as the default audio device and check.
a. Press “Windows Key + C” to open a “Charms Bar”
b. Go to settings and type control panel and select sound.
c. Click the Playback tab. Notice the check mark next to the default device. For most users, the default device is Speakers. Make sure that your audio settings are configured as expected. Follow these steps:
d. On the Playback tab, select the playback device, click Properties, click the Advanced tab, and make sure that the Default Format is set to the value that you expect. When you finish, close this window to return to the previous window.
e. On the Playback tab, select the playback device, click Configure, and then make sure the configurations are set correctly.
f. Select the sound device that you want as the default sound device, and then click Set Default.
g. Click OK to save your settings and to close the Sound dialog box,.
Hope this helps.
