I have a new Dell XPS 13 9350 (only a few months old)... I noticed that the Microphone is not working in any applications I try. I have gone through the Dell diagnostic as well as the Windows 10 diagnostics but nothing seems to fix the issue.
I am running the latest drivers (126.96.36.19937) from the Dell support web site.
I have tried to remove the Realtek drivers and go with the native Windows 10 HD Audio Drivers. This did appear to fix the issue, but then I updated the BIOS to 1.3.3 and now it doesn't work again. Not sure if the BIOS update broke it or it was just a coincidence and it would have failed after a reboot anyway. I may attempt to role back the bios and see what happens.
I don't believe it is a hardware issue as I have seen the mic working fine with the Windows 10 drivers.
Has anyone else seen this problem or have a solution?
The problem is I don't know if the MIc was working from the beginning. The day I got the laptop I update the drivers from the website right away. I work in IT and always like to have the latest drivers.
I have a similar issue running the same latest drivers. From a cold boot the microphone doesn't work (if I go into Sound/Recording the microphone levels are absent and the dialogue box hangs). If I cold boot then Restart the microphone works fine. Not a great solution but it seems to work every time. Any solution to get the microphone working from the initial cold boot would be appreciated!
I think resolved my problem. I noticed whenever I clicked on the mouse pad the mic would work. As soon as the click stopped the mic stopped working. This got me thinking it was a hardware issue. So I gave a firm press all along the front of the laptop. Ever since then the mic has been working fine. I can only assume there was a loose connector and by pushing it popped it into place. Time will tell if it is fixed. I am still under warranty so will keep an eye on it.
