Inspiron 7590 - integrated microphone not detected

[Olomorn]

Hi everyone,
I have trouble using the integrated microphone on my Dell Inspiron 7590. The audio (integrated speaker, usb adapter, blutooth, etc.) works perfectly, the webcam works great, but the microphone is not detected at all, not even in the settings.
I'm also kind of a noob so don't hesitate to ask for details... Thanks in advance!

Edit:
So there is information I should have provided so here it is ^^'

Then I tried looking the "dmesg" infos but I did not find any error related to what would be my internal microphone, and the journal did not contain anything related to the problem either. (i could have missed it though)

Welcome to Manjaro!

How to provide good information in your posts

When asking questions in the forum, it would be most helpful to all members if you provide some basic information. When you provide info from the terminal, usually from your logs, you have to format it so the content is easy to read. First copy and paste your text/terminal/code into the post Then select the text/code and click the post edit toolbar button </> . Another handy way is to use 3 backticks ` at the start and 3 more at the end of the text like this: ``` Paste text or code here …

[Olomorn]

Okay, I edited my post to include the output of the inxi command. I did not find anything in the dmesg output or the journal and they are probably too long to be posted here in their entirety.

[Fabby]

Nearly midnight here now, so I'll respond tomorrow. In the meantime, please execute:

alsamixer

• Press F6 and take screenshot, press Esc
• Press F2 take /proc/sound/devices, press Enter, take screenshot, press Esc, press Esc, press Esc

Post screenshots

[Olomorn]

I'm in no hurry, thank you for helping me

[Fabby]

You seem to have 2 capture devices (=microphones) so that's good:

alsamixer

then press F4 and use ← and → to switch between devices and use ↑ to ensure the volume is higher than 0 and ↓ if you end up making your microphone too loud.

[Olomorn]

I tried that but I only have one capture device displayed (see image below) and it is not detected by any application that I use (gnome settings, discord, firefox, etc.)

[Fabby]

Install cheese and see if that works?

[Olomorn]

I tried recording a video and rubbing the microphone and speaking near it, but to no avail
And to be clear the microphone works like a charm on windows.

[Fabby]

@nikgnomic Calling the surgeon to the operating room!

I'm at the end of my troubleshooting steps here... Can you have a look, please?

[Olomorn]

Still no one? I can provide any other information if you tell me how to get it!

[Fabby]

@nikgnomic Do you have any idea? If no, do you know who might be able to help here?

@Olomorn can you provide some info from Windows??? (EG, driver, hardware, ...)

I really don't know how to proceed any further here: all out of ideas...

[Olomorn]

I didn't find much, in the device manager it is listed as Intel Smart Sound Technology (Intel SST).

[Fabby]

@Olomorn

Intel Smart Sound Technology

That should just work!

Does it still work under Windows??? (Try a Skype test call if you have Skype or Sound Recorder if that still exists nowadays or whatever...)

[Olomorn]

Yes it does, I often have to reboot on windows to make my video calls, and then come back to manjaro to work

[Fabby]

Hold on for a minute!

Try the following:

• Shut down the machine completely.
• Cold boot straight into Manjaro and see if it works then!

(Grasping at straws now)

[Olomorn]

I'll do that, but I mean, I am in manjaro right now, and barely ever use windows except for the aforementioned video calls (and the occasional video game)

[Olomorn]

Okay so this did not help but also I noticed that the integrated speakers no longer seems to work and have been replaced with a "dummy output", and after seeing that I tried to plug in my jack headset and it is not detected anymore either, but my bluetooth earbuds works perfectly

[Fabby]

That sounds like a side effect issue:

• warm boot into Windows,
• warm boot into Manjaro,
• unpair the BlueTooth
• and try again...

[Olomorn]

There is still only the dummy output!
And since I would only use the integrated speakers for video calls, I am not sure if this is a new problem or not! I am quite sure I didnt do anything to the drivers or anything...
