Microphone stopped working

Hi,
My microphone has stopped working, and I am unsure why, I suspect it was the upgrade to Linux 4.0.1.
I am unfortunately not sure what steps I should take to debug this. The audio device is detected, and I even get output sound. It used to work. I went through the wikis, and old forum posts, but couldn't find anything that seemed to relate to my problem
There is just no audio detected, but I made sure it is not muted.
It is not a hardware issue - I tested it on Windows, and it worked.
Any ideas on what I could do to debug?

Thank you

try

Re: Microphone stopped working

I'm using a Razer Blade 14" 2015, and I have gone through the wiki procedures, none helped

Re: Microphone stopped working

So of this have you tried ?
And what responses ?
Did you unmute the channel and enabled the capture ?

Re: Microphone stopped working

I tried all the troubleshooting steps, with no difference in behavior: the microphone just doesn't get any input.
The channel has always been unmuted, and with capture enabled.
I did realize something today, that might lead to more interesting troubleshooting measures: it works when I plug in headphones.

If I go to pulseaudio volume control, without headphones connected, the selected microphone is Microphone (plugged in), and the other options is Internal Microphone (unplugged) - I'm unable to select that one.
If I plug in the headphones, though, the Internal Microphone gets selected, and switches to plugged in.

I am assuming that the microphone that pulseaudio/alsa think is plugged in is the headphone/microphone jack's microphone (it's only one jack for both), and they're disabling the internal microphone. When I plug in an actual heaphone set, it corrects that mistake, activating the internal microphone. It seems to point to a hardware issue, but I'd assume Windows would then have the same issue, so I'm at a loss

Any help is appreciated.

Re: Microphone stopped working

Many peoples facing problem using pulseaudio. What about to disable/remove it ?
