ENVY x360 Convertible W0U47AV
Microsoft Windows 10 (64-bit)

The audio is NOT working. There is a red "X" through the speaker and it says "NO AUDIO OUTPUT DEVICE IS INSTALLED".

This keeps happeneing randomly 2-3 times ad day and gets gixed if I disable and enable the Conexant ISST Audio driver from device manager or restart my PC. The laptop is less than a month old and this problem is there from the start.

 

What I have observed:

1. The troubleshooter is useless. It comes back with nothing

2. When I hover over the sound icon "No audio devices are installed"

3. DEVICE MANAGER: under sound, video and game controllers, there are two listed: Conexant ISST Audio and Intel Display Audio. BOTH say the device is working properly and that the latest version of the drivers is installed. ALSO, there is no option to roll the drivers back (the option is grayed out) because this is a new computer so therefore, there was no previous driver.

4.In Device manager under Audio Inputs and Devices, the speaksers (Conexant ISST Audio) driver is missing, but it comes back if  I disable and enable the Conexant ISST Audio driver in sound, video and game controllers  from device manager or restart my PC.

5. ALl the drivers are the latest versions

6. The BIOS is the latest version

7. I have tried uninstalling and reinstalling the sound driver (both from device manager and add/remove programs), it fixes the problem then but the red 'x' thing on the spekaer still keeps happening randomly.
