envy 13 no sound

HP Recommended
envy 13 ah-0002la
Microsoft Windows 10 (32-bit)


my laptop is not playing any sound through the speakers (it only works when connected to a bluetooth device). I've been having this problem since I got it, but it used to get solved with audio check. Not anymore (ever since the warranty expired -amazing capitalism trick from hp??). 

if I run audio check it automatically examines audio devices, then it prompts to a screen with a "test audio" button that moves for about 1/10 of a second. below that there's a "no sound" button and when I click it brings yet another screen with another test audio button. This is the one that used to do the trick, but now it doesn't even last the 4 seconds that it was before.


I've also tried running the HP hardware diagnostics, but it has brought a series of error messages:




now, it gets even worse, because the microphone is not responding either. I tried to record a video with the built-in camera and got this message: 0xA00F429C<MicrophoneNotAvailable> (0xC00DABE0)


any help would be appreciated


thank you
