Hi Rammi,
Welcome to the HP Forums!
I would like to take a moment and thank you for using the forum, it is a great place to find answers. For you to have the best experience in the HP forum, I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I grasp that when playing video you have picture but not sound and you get the error message that the device is being used by another application. Please close the any  applications using this device and try again.
I suggest you try these steps to start with.
Press the Windows key + C to open charms
Type Control Panel in the search bar and open it
Go to Sound and open it
select speakers and headphones and  open
click on the advance tab
change the sample rate and bit depth to the lowest settings  and click OK.
Try playing your video again. If this works you can go back and try a higher settings until the issue returns and then leave it set on the one just below that.
If you are still having an issue, and it was working previously , do a restore back to when it was working.
Using Microsoft System Restore (Windows 8)
You could also try reinstalling the original drivers using the recovery manager Using Recovery Manager to Restore Software and Drivers (Windows 8)
If your issue still persists I would try the following steps.
Boot into safe mode and try playing the video do you have the same issue?
Windows 8 Safe Mode.
If the issue is not present, then it would appear there is a conflict that needs to be addressed.
Using Microsoft System Configuration (Windows 8)
In the instructions it will advise you to enable items one at a time. This could prove to be very time consuming, so I suggest doing a 50/50 process and then start narrowing down to locate the issue.  This should save you some time.
I hope this has helped.
