It is possible that you are missing the audio driver for your computer. The audio driver is the piece of software that will indicate the operating system how to communicate with the audio system. So, let's check your audio driver version, use the link below to find the steps;
I would also like to check the Intel® HD Graphics version you have installed, from our end the audio driver is included in this driver. So, provide this information too; go to Device Manger> Display adapters> Intel(R) HD Graphics right click on Properties and then go to Driver, you will be able to see the version installed.
I have tried every IDT driver I could find, I am running Microsoft Win-10 audio drivers now and when is set speakers and headphones as default and run test the green audio VU meter responds as it should but there is no sound from the laptop speakers.
It seems all in/out external audio must go through the 3.5MM jacks on the side of my computer when it was working correctly if you plugged in external speakers the internal speakers shut off, external microphone would shut off internal microphones.
This all started after a Win-10 update, when I was editing a movie and wanted to add a voice over. I plugged in my external Mic. as I have done many times in the past and set it as default but there was no audio coming in. I then tried my audio editing software and it didn't work either, it reported "incompatible audio drivers"
I started searching on line for advice, After many tries with different drivers to no avail HP recommended uninstalling all drivers associated with audio, I did so and the 3.5MM jacks disappeared System Diags. report Audio [P] Failed 9W72J2-6AT8GX-PXGX1F-21BN03
I am not the only one with this problem I have seen many people on line whit the same problem they all seem to have an HP similar to mine.
Model: HP ENVY 17 Notebook PC
Serial Number: 3CO23499TY
Product ID: A6U49AAR
I have worked around this by using a USB to 3.5MM audio dongle, I also have an audio mixer so I can do just about everything I need to and both NCH WavePad and Audacity have provided updates to work with the Win-10 audio drivers.
