Dear gbonyo -
I understand that after installing Windows 8.1, your speakers and headphones do not work.  Well, that's annoying...  I will try to help. 
- Before going through these steps, make sure that the speakers and headphones are connected to the correct ports. (I know this sounds silly, but sometimes it happens.)
The first and simplest thing to try is the audio playback troubleshooting tool:
1. With the headphones and speaker plugged in to the laptop, type "troubleshooting" at the Start screen to open the Search charm, and then select Troubleshooting from the search results.
2. Under Hardware and Sound, click Troubleshoot audio playback and then click Next when the Playing Audio window opens.
3. A new window opens. Select the device you would like to troubleshoot. Then click Next and follow the on-screen instructions.
4. If a recommended action displays, select Apply this fix or Skip this step to continue to search for other problems.
If the above does not resolve the problem (and/or it does not find your speakers/headphones) it could be that the laptop does not know that it has speakers/headphones attached to it.
1. From the Start screen, type "sound" to open the Search charm, and then select sound from the search results.
2. Click on the Playback tab.
3. Right-click an empty area of the Sound window.
4. Click the check boxes to select Show Disabled Devices and Show Disconnected Devices.
     If the device is listed as "Currently unavailable" or "Not plugged in," disconnect it, and
     then reconnect it from the port.
5. Test the device by sending a signal from the sound source (For example: Play an mp3 file).
6. Look at the bars next to the device name on the Playback tab:
If the gray bars next to the line-in audio device name change to green, the device is active and an audio signal is passing through the line-in port. The issue should now be resolved. 
If the bars remain gray and inactive, the computer is not recognizing a signal. Leave the Playback tab open and proceed to the next step.
7. From the Playback tab of the sound window click the port that you want to use (there could be one or more ports).
8. If the device you want to use contains a small circle with an arrow pointing down, the device is disabled. To enable the device, right-click the device name and select Enable.
9. Click Set Default to make this device the default line-in audio device.
10. Click OK to make the changes.
Please let me know if this resolves the problem.  If it doesn't, we can try a couple of other things.
Sincerely,
