[SOLVED] PulseAudio not detecting laptop's built-in microphone.

Before anyone marks this as an already asked question, I seriously am clueless as to what the problem is and googling anything at this point just places me in a loop of articles I've already seen.

Story:
After some time of my built-in mic not producing any sound, I finally fixed it. But shortly after that, I tried using Qjackctl to play some music through my microphone. At that point, I didn't touch any settings in pavucontrol or in Alsamixer. I eventually stopped using Qjackctl, closed it and decided to use my microphone. It was producing no sound at all. All it detects is my headphone's microphone, which doesn't work (CM108 audio controller). Anyways, fast forward to googling a ton of things and trying a lot of them, my built-in microphone isn't even detected anymore. It happened straight after restarting pulseaudio. My built-in mic had an "Analog Stereo input" profile, originally was "Analog Stereo Duplex". Here are all of my pavucontrol settings  - https://imgur.com/a/ZYBpG86 . You can see in the second picture that I have some activity on my "Monitor of CM108 audio controller" but that seems to be the music I'm currently listening to. As you can see, no built-in microphone is present in the settings.

If anyone wants more information on my settings/drivers/inputs , tell me.

Re: [SOLVED] PulseAudio not detecting laptop's built-in microphone.

Welcome to the boards, Berdy

How exactly did you "finally" fix it? That wording looks like you've consciously done something but you aren't specifying what exactly. Please provide all adjustments in that regard.

I can't look at the pictures at work, however there's less information in there than would be contained in a 

pacmd list-cards
pacmd list-sources
pacmd list-source-outputs
arecord -lL
amixer -c$insert index number of the correct card from arecord -l output$
sudo fuser -v /dev/snd/*

please post that in [ code ] tags, preferably during an attempt to actually use your microphone.

Re: [SOLVED] PulseAudio not detecting laptop's built-in microphone.

And there we have it™ you have a jack daemon started that occupies access to  your main card. Why? Did you do that consciously? Where do you start it, do you want it to be started? If you want it to be started, read: https://wiki.archlinux.org/index.php/Pu … rough_JACK if you don't want it to be started find out what starts it and whether it can be configured to use pulse instead.

O wait you did mention qjackctl, check through it's  config and ensure no kind of autostart is enabled, and go through your session startup files and check that you didn't leave some script lingering somewhere.

Re: [SOLVED] PulseAudio not detecting laptop's built-in microphone.

Yeah I noticed that while looking at the command too.

I checked the config, it seems as if all autostart is disabled.

What I did, however, was 

killall jackd

Thanks for the help!

Re: [SOLVED] PulseAudio not detecting laptop's built-in microphone.

Well I'd assume that this will be back if you don't figure out what starts it on boot/login, however if this works for you, please mark as [SOLVED] by editing the title in your first post: https://wiki.archlinux.org/index.php/Co … ow_to_post
