Microphone does not work on new Dell Inspiron 7590

  • 772

I am using Ubuntu 19.10 with the new Inspiron from Dell - 7590 (model info from Arch Linux)

The microphone does not work, but speakers do. I tried anything - building kernel 5.5.6 and updating alsa to 1.2.1, but it does not seem to help. The integrated microphone as well as the 3.5mm generally do not work, but there seems to be activity in pavucontrol (I think this is white noise). Also there is nothing shown as input (when I go to settings -> sound), but I can see something in pavucontrol

My multimedia controller is:

00:1f.3 Multimedia audio controller: Intel Corporation Cannon Lake PCH cAVS (rev 10)
    DeviceName: Onboard - Sound
    Subsystem: Dell Cannon Lake PCH cAVS
    Flags: bus master, fast devsel, latency 32, IRQ 177
    Memory at ed318000 (64-bit, non-prefetchable) [size=16K]
    Memory at ed100000 (64-bit, non-prefetchable) [size=1M]
    Capabilities: [50] Power Management version 3
    Capabilities: [80] Vendor Specific Information: Len=14 <?>
    Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel, snd_soc_skl, sof_pci_dev

No input devices show by default on clean install of Ubuntu. I tried 18.04 (LTS) but the result is the same, so I switched back to 19.10. When I run pavucontrol it shows this:

I can see noise and that the mic is recording something (but I cannot control it from the sound settings) but it does no react to my voice.

Output from cat /proc/asound/card0/codec* | grep Codec: 

Codec: Realtek ALC3254
Codec: Intel Kabylake HDMI

I hope someone can help me out here, I would be really grateful. Thanks in advance!

Update: seems the mic now works under Archlinux: https://wiki.archlinux.org/index.php/Dell_Inspiron_15_(7590)

Update #2: With a little help from sof developers, I think I can get my mic (as well the one from many other dell laptops) working - https://github.com/thesofproject/sof/issues/2502

  1. You might try an OEM kernel image (or the linux-oem package, there is also a tools and modules package) as these sometimes have better support of OEM Hardware (especially Laptops) and as far as I recall, Dell is contributing there or actively supporting it.

    #should install everthing basic you need
sudo apt-get install linux-oem
#or for a >= 5.0 Kernel
sudo apt-get install linux-oem-osp1
#Might want to install oem tools but try it without first if they are not automatically installed

    If the OEM-Kernel does not help you you might try checking the differences between your 19.10 and 18.04 manufacturer image or if the problem still persists when booted from a live or USB stick using the manufacturer image.

    If the problem persists with the officially supported image, then the driver really might not support using it the way you want.

  2. Be sure to use an application that can record audio. See the message in Puva, recording tab. Try gnome-sound-recorder. You can find it in Synaptic. Also be sure that your web-browser is capable of recording.

    1. First check the mic sound level. To check the sound level install alsamixer. To do that use following commands: 

      **sudo apt-get install alsa-utils**

**sudo apt-get install alsamixer**

    2. Once alsamixer is installed then run following command to run it 

      **alsamixer**

    3. Then press F6(Function key to check the sound cards) and select appropriate sound card and press enter key.

    4. The screen will show volume level for Master, Speaker, Headphones and MIC (Depending on the system, this list may vary). Make sure MIC volume is not zero.

  4. There is a way to fix this.

    I have the same laptop and I'm also running 19.10. As the OP, I also managed to solve this problem. I'm writing this answer as a "how to" guide, just to help others having the same problem as we had. The oem kernel proposed by @Ritualmaster is tested and at least in my 7590+ubuntu19.10 configuration, is not working.

    The problems:

    • The sound(speakers, line in-out, dmic) is fully working using sof, but the ucm configuration files needed are not in the master branch of the project nor in Ubuntu's installation.

    • Ubuntu's update to 5.3.0-42 kernel breaks sof causing failure to the sound system, leaving a DummyOutput device for sound output.

    So I'll try to document the required steps for the solution:

    1. Blacklist "snd-hda-intel" and "snd-soc-skl" modules in order to let the linux kernel to load the sof driver. The driver is already installed as it is part of the kernel since 5.2 (I think).

    sudo touch /etc/modprobe.d/blacklist-snd.conf
sudo echo "blacklist snd-hda-intel" >> /etc/modprobe.d/blacklist-snd.conf
sudo echo "blacklist snd-soc-skl" >> /etc/modprobe.d/blacklist-snd.conf

    2. Fetch the sound card configuration files from the sof project repository. This step requires git. So if you don't have it, install it via sudo apt install git. The configuration files are not in the master branch and so both the existence and the contents of them is not guaranteed. For that reason we will checkout the files exactly in the right version manually.

    cd ~
git clone https://github.com/thesofproject/alsa-ucm-conf.git
cd alsa-ucm-conf
git checkout -b inspiron f083700
sudo cp -r ucm/sof-skl_hda_card /usr/share/alsa/ucm/

    3. If you have installed the kernel update "5.3.0-42", you also have to make sure you are booting to the previous "5.3.0-40" version every time. One simple way for doing this is editing grub. Find /etc/default/grub and delete line GRUB_DEFAULT=0. Then add the lines below

    GRUB_SAVEDEFAULT=true
GRUB_DEFAULT=saved

    Now update grub and reboot

    sudo update-grub
sudo reboot

    4. Assuming you are using inspiron 7590 ;) make sure you press F1 when the dell logo appears while booting, in order to bring up the grub menu. From this menu select advanced and then 5.3.0-40. Bringing up the grub menu is not necessary every time, only once. In the previous step we have set grub default selection to "saved". That means it will continue to boot the last selected version from now on.

    That's it. Hopefully the system will boot and the sound cart will be detected just fine.

    For example in my pulseaudio volume control: enter image description here and enter image description here

    Note 1: If mic level is still low, you can raise it in alsamixer.

    Note 2: If there is a better way of selecting kernel to boot let me know.

  5. that's what worked for me: install sudo add-apt-repository ppa:kaihengfeng/fix-lp1869819 and put it

    options snd-hda-intel dmic_detect=-2
options snd-hda-intel model=dell-headset-multi

    into file /etc/modprobe.d/alsa-base.conf

    It works for ubuntu 20.04 on Dell G3 3590!!!

  6. While hoo2's answer is not working for me, it helped me to find a solution.

    I am running Ubuntu 20.04, on Dell Vostro 7590 with kernel version 5.6.0-1020-oem.

    Here are the steps:

    1. Install SOF firmware and topology binaries:
    git clone -b stable-v1.5.1 https://github.com/thesofproject/sof-bin.git
cd sof-bin
sudo ./go.sh
    1. Blacklist snd-hda-interl and snd-soc-skl by adding following lines to /etc/modprobe.d/alsa-base.conf:
    blacklist snd-hda-intel
blacklist snd-soc-skl

    Note that if you have some other changes to that file, it is good to revert them (e.g. remove options snd_hda_intel dmic_detect=0).

    1. Reboot
