HI DaveRay59,
Thank you for posting in Microsoft community!
I am sorry to hear that you have issue with sound in Windows 8. I will definitely help you with this.
What is the make and model of the computer?
You can download the High Def Audio Driver here is the link

Let’s follow the steps from the following link and check if it helps.
If you’re unable to overcome the issue try installing the drivers in Windows 7 compatibility mode
Follow the Steps:
Set the default playback device as Speakers:
a. Click on Start and then click on Control Panel.
b. Click Hardware and Sound and then Click on Sounds.
c. Under Playback tab, right click on the empty area and make sure “Show Disabled Devices” has a check mark on it. If Speakers are disabled, it will now show up in the list.
d. Right click on the device and select “Set as Default”. Click OK.
Please post back if you have any questions. I will be glad to provide you with the additional options available that you can utilize to get the issue resolved.
