Hi!
A few weeks ago, I got a message "A Conexant audio device could not be found. The application will now exit." The sound button has an X on it as well, saying "No audio output device is installed." I tried uninstalling and reinstalling audio driver and Windows 10 troubleshooting for this particular issue - nothing. I can not remember exactly what did I do, but the next morning it suddenly worked again. After a few days the problem returned and I tried more things than before, today I even did a factory reset on my laptop, but the problem was not solved. What else could I try before sending the computer to be repaired?
Laptop specifications:
OS: Microsoft Windows 10 Home
Model: Vostro 14-5459
Processor: i5-6200U
Audio: Intel(R) Display Audio; NVIDIA Virtual Audio Device (Wave Extensible) (WDM)
