No sound When i go to the windows media player and try to play music it says cannot play back audio stream no audio hardware is available or the hardware is not responding what can i do to fix the problem.

As you may have already notice, there isn't a problem with your driver.
However to gain a better understand the problem you rule out a couple of things. However, if the this problem is only present in windows media player. Then you should try another play i.e. VLC media player.

1. Go to you device manager and make sure the device is working properly. If not try uninstalling the device, restarted the computer letting windows discover the device again.

2. Next go to windows media player file (press "alt" key to get toolbar in newer version. Select options -> devices select your speaker -> properties and be sure that your audio device is available and selected.

3. Finally if all these options has failed, please use an alternative media like the one mention above (VLC media player).

I hope this have been a great help in your troubles. Please provide feedback on the solution.

It sounds like you're using a set of stereo speakers to play a surround sound output. I would try going in the TV menu and turning off surround sound

First Check you have Properly inserted Speaker Jack in right Jack in your computer sound panel. and also make sure that speakers are working perfectly.

if above connection are Ok then Try to play Other Music files in other Music Player like WinAmp, Cyberlink etc... If sound is comming then Install newer version of Windows media Player. other wise there is

I would recommend trying to see if these drivers will correct the issue..I can't see you having a laptop, and all of a sudden, there is no sound card installed? So, I think the drivers will solve the issue. You will need to enter serial number of laptop..click on the below link..

Windows Media Player cannot play several files in the playlist. This might be caused by one or more problems.
To find information about the specific problems, click the Now Playing tab, and then click the blue or red icon next to each file in the List pane.
In some cases, you might encounter this error message if there is a problem with your sound device, such as a sound card or sound controller. For example:

• Your sound device requires an updated driver. To determine if an updated driver is available, see Windows Update or see the sound device manufacturer's Web site.
  
• Your sound device is not functioning properly. To troubleshoot the problem, see Windows Help and Support or refer to your sound device's documentation.
  
• You do not have a sound device installed on your computer. Install a sound device, and then try to play the file again

Solution : Reinstall Driver, try to find your accompanied CD that goes with your pc
