Internal microphone not working

Hello,

I just installed Archlinux, and my internal microphone does not seem to be working.

I have installed pulseaudio, pavucontrol, and done everything that is listed here:  https://wiki.archlinux.org/index.php/Pu … Microphone.

The speakers work well. It's only the microphone that isn't working.

I test it using `arecord -vvv -f dat /dev/null`, but the max peak value stays at 0%.

Another funny thing is that on alsamixer, on the capture view (f4), I can see two input sources, one being "headphone mic",
and the other one "headset mic". I have activated both "captures" using the spacebar, and I've also raised the bars to ~50%
on every value on the capture view.

I'm using a Dell Inspiron 15 7000.

Could anyone help me?

Re: Internal microphone not working

I tried today with an USB microphone, and it did work. I didn't even had to do any configuration. I just plugged it in.

On the other hand, the internal microphone is still missing.

Any ideas?

Re: Internal microphone not working

Your mic is there but you are recording from the wrong source (you hook into the output monitor) and on a low volume: 

pacmd set-default-source alsa_input.pci-0000_00_1f.3.analog-stereo
pactl set-source-volume alsa_input.pci-0000_00_1f.3.analog-stereo 80%,80%
#Potentially needed if pulse has stored the fact that your "preference" is the output monitor
pacmd move-source-output 7 alsa_input.pci-0000_00_1f.3.analog-stereo #This 7 is unstable, recheck correct number with pacmd list-source-outputs, or just switch in pavucontrol, ensure the mic is selected, not the output monitor

Re: Internal microphone not working

Thanks, I see the issue!

Nevertheless, I can't seem to change the default source. The `pacmd set-default-source` command doesn't seem to do anything:

$ pacmd set-default-source alsa_input.pci-0000_00_1f.3.analog-stereo

$ pacmd list-sources

There is still a * right next to index 0.

I tried moving the source output using the `pacmd move-source-output` command, but the max peak value stays at 0% still.

 $ pacmd list-source-outputs

		module-stream-restore.id = "source-output-by-application-name:ALSA plug-in [aplay]"

And when I run a `pacmd list-sources`, I get the same result as above.

Is there a way of forcing the output-source, other than using the `pacmd set-default-source' command?

EDIT: I also tried adding "set-default-source alsa_input.pci-0000_00_1f.3.analog-stereo" to the /etc/pulse/default.pa file, and then
restarting pulseaudio, without any results.

Re: Internal microphone not working

Did you found the solution ?

Same issue here : no microphone detected on a Dell Inspiron 15 7000 (7590).

Re: Internal microphone not working

I'm also having the same issue with the Inspiron 15 7590. Here are my alsa controls:

https://pasteboard.co/IZF2Uex.png

I've tried playing with each of the controls. There are reports that the "Digital" control affects the internal microphone, but this has had no effect for me.

[edit]
I've now bought a headphone / microphone combo with a TRRS connector, and I'm really struggling to get a good signal from that too. I *can* get something through, but the noise floor is *very* high. Something is definitely missing from the driver for this laptop's audio setup.

Re: Internal microphone not working

Lower the Headset Mic Boost. Most "boost" controls don't add something useful and should be toned down. Should this not be sufficient post at least the amixer command of the relevant card, alsamixer screenshots can lack a lot of context.

Re: Internal microphone not working

Thanks; I tried every control. It turns out the microphone requires DSP firmware and will only work with the new SOF driver (and the sof-firmware package).

I've created a bug report against the SOF driver that's being tracked here:
