Windows 10: Mic pick al audio input

I don't know why, but my mic in picking all the playback sound, even if my headphones and speakers are closed. It's acting like a speaker. I have to mention that the "Listen to this device" is't checked.

Remote device doesn’t detect audio input

The problem that the audio input of my laptop is not visible by the remote computer. I did troubleshooting steps such as checked settings, group policy, remote desktop services. No problem. But it remote audio device isn’t picking up input from my
mic.

 

nokia lumia 920 mic problem

I've also been having a mic issue for a while (four months), but all of the other discussions don't quite describe what I've experienced. I just upgraded to 8.1 hoping that would fix the issue, but it still hasn't been resolved. Here's what I'm experiencing
(Lumia 920):

• Mic does not pick up audio input to Cortana.
• Mic does not pick up audio input when listening for music, although it always finds the exact same song (Spaceflight).
• People I talk to say the audio is usually muffled somewhat. It seems to be random: Sometimes they hear me better on speaker, sometimes close to mic, and sometimes the call quality seems to become worse a few seconds into the call. Sometimes cycling
  the speaker on then off makes it better.
• Using a bluetooth headset for audio input does work fine.
• Mic does not pick up audio recordings (like in OneNote), tested making sure both mics were clear, then covered one mic, then the other. All I hear from the recording is straight static.
• Phone does recognize whether or not headphones are plugged in (seemed to be a recurring issue among some).
• Interestingly, mic DOES pick up audio in recorded videos.

Troubleshooting steps:

• Cleaned out holes on both mics.
• Reboot phone.
• Soft reset phone.
• Update phone to WP 8.1 dev preview.

The phone's over a year old, so yeah I know I'm not getting a warranty replacement or anything. I'm torn whether this is a hardware issue (because software updates don't seem to affect it) or a software issue (because there are limited circumstances where
the issue doesn't occur). If it's a hardware issue I'll probably just get a new phone (a 930 would be sweet, but alas, I live in the US). If it's a software issue I'd like to know if there are any bug-fixing steps I can try.

Can't isolate line audio from mic input; audio driver not showing.


Excellent reply. I set Audacity as you suggest and it works. To my perfectionist mind, there's one flaw: with all volumes to max, the recording level is rather low, as the attached snip shows. Any ideas how to increase it? My previous Win 7 laptop allowed far more level than this, using a Realtek driver.
