Replaced my screen on wife's SP7 but now mic isn't working!

Hi - I had to replace my wife's screen for this device. Its very challenging but your guide was really useful! I was finally in the position to put the screen back on with adhesive but did a final test (I replaced the screen and as instructed damaged the wifi antenna so purchased a replacement of that too).

But now - the microphone(s) aren't working! Windows picks up the device but zero sound input. Any ideas or tips on this issue? I have seen the microphone cables for sale but not sure that will fix my issue.

Any help much appreciated!

Hi all - I figured it out. When I replaced the wifi areial part I did not re-connect the two microphone sensors - they are super small so I missed them.

If anyone else has the same issue feel free to reach out!
