After the last update, my microphone is not working anymore

ericmilaneze · March 16, 2020, 4:33pm

Hi,

I have a Dell Latitude 3000 with Fedora 31. Details:

Static hostname: dell-notebook
Icon name: computer-laptop
Chassis: laptop
Machine ID: 75059346d58e41889e47b65977ab6d95
Boot ID: f54ad53ab0ff44c398739f9edb0f76c7
Operating System: Fedora 31 (Workstation Edition)
CPE OS Name: cpe:/o:fedoraproject:fedora:31
Kernel: Linux 5.5.8-200.fc31.x86_64
Architecture: x86-64

After last Fedora update, the microphone stopped working. It’s like there’s no internal microphone since there’s no input to be chosen.

When I use the live flashdrive or Windows (which I really don’t want to use), it works percectly.

This is what I see when running the following command:
alsamixer -c0 -Vcapture

I also used the following commands:
alsa-info.sh --no-upload

Parts of the resulting file:

Does anyone have any idea what I can do in order to have my microphone back?

HI, @alph4num3ric,

I managed to do what you advised, but it didn’t work unfortunately.

The file /etc/default/grub is like this now:

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="resume=/dev/mapper/fedora_localhost--live-swap rd.lvm.lv=fedora_localhost-live/root rd.lvm.lv=fedora_localhost-live/swap snd_hda_intel.dmic_detect=0 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true

Then I used the following command:
sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Rebooted.

It still can’t find the laptop internal microphone.

ericmilaneze · March 16, 2020, 9:08pm

Update: I ran the following command:
arecord -l

Got this as a result:
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC3204 Analog [ALC3204 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0

Then I updated the file /etc/pulse/default.pa making the line with this:

#load-module module-alsa-source device=hw:1,0

uncommented like this:

load-module module-alsa-source device=hw:0,0

It made the input device appear, but it didn’t work anyway.

Please, someone help me with this!

ericmilaneze · March 16, 2020, 10:03pm

Solution:

I did two things:

1 - Ran the following command:
sudo dnf install alsa-ucm alsa-firmware

2 - Upgraded to this kernel version:
Linux 5.5.9-200.fc31.x86_64 x86_64

That made the trick and it’s working like a charm now.

debajiteziodutta · March 28, 2020, 12:50pm

Hi, I am also having same problem, apart from Audacity(application) my inbuilt mic does not work anywhere be it Skype, Firefox or google hangouts.

Fedora Workstation
My kernel version = 5.5.11-200.fc31.x86_64
AlsaMixer v1.2.2
/proc/asound/version= Advanced Linux Sound Architecture Driver Version k5.5.11-200.fc31.x86_64.

Please let me know if any other information is needed.
Do help.

borod108 · March 31, 2020, 8:32am

any news on this? I have the same problem

balajib · March 31, 2020, 4:36pm

Try this
rm -rf ~/.config/pulse/*
sudo cp /etc/pulse/* ~/.config/pulse/

Reboot system

borod108 · April 1, 2020, 12:23am

Thank you, I tried, nothing changed.
Also, as a side note, the file structure is very different between those folders

svenka · April 1, 2020, 8:37pm
