Internal Microphone Not Detected [Lenovo Carbon X1 7th Gen, Ubuntu 19]

Question

UPDATE: This guide's script ended up working for me, even though I had done all the commands individually on my own previously. Don't really know why, but wanted to throw it out there for anyone else reading this.

(As a preface, I am very much a noob when it comes to Linux, but I have already tried following advice from many different forums to no avail. I have tried throughout to provide clear and necessary information about my system's setup.)

I bought the Lenovo X1 Carbon 7th Gen with the intention of running Ubuntu. When I encountered the Wifi problem described here, I settled on using Ubuntu 19 even though I would prefer LTS with Ubuntu 18. All was going well with the system until I needed to use the microphone for a Zoom call, when I realized that my system did not detect any input devices. See what my GUI sound settings look like - there are no input devices to choose from, but my speakers are working.

After troubleshooting online, I found this forum post describing how to fix the problem when running Arch. I decided to try and follow the guide on my own, since this Lenovo forum post implied that this guide isn't Arch-specific and might work for other distros (e.g. Debian, Ubuntu). However, even after following the guide (taking into account the typos pointed out by user tbw in reply #9, I couldn't get the microphone to be detected.

Currently, this is what my /etc/modprobe.d/blacklist.conf looks like.

# blacklist snd_hda_intel
# blacklist snd_soc_skl

When I uncomment the above blacklist lines, there is no difference in the input sources available but I am unable to use my speakers. Thus, I've left these lines commented for the time being.

Currently, this is what my /etc/pulse/default.pa looks like.

load-module module-alsa-source device=hw:0,7

And here is the result of the following command.

# ls -l /lib/firmware/intel/sof-tplg/
total 200

-rw------- 1 jmarkey jmarkey 32787 Aug 14 13:27 sof-hda-generic.tplg.original

Thus my current system resembles the result of the guide. I even made the edits to the pulse daemon described in the final edit of the original post on the thread, and this is what my /etc/pulse/daemon.conf looks like.

enable-lfe-remixing = yes
; lfe-crossover-freq = 0
lfe-crossover-freq = 250

Here is information about my hardware.

Please let me know if I should post any other information. Because I'm a noob, I'm not sure if the above information is too much or not enough.

I've also tried a few other fixes as well, notably messing around with alsamixer and pavucontrol, but to no avail. Since messing around with these fixes, the light behind my F4 key has been lit (denoting that the microphone is disabled), but I am unable to turn it off by pressing it (while holding the Fn key and while not holding the Fn key).

--------------EDIT 1---------------

Here's the output of the following command (with the lines commented in the blacklist file).

dmesg | grep sof

And then with the blacklist lines uncommented.

I'm having the same problem. Hopefully the maintainers see this! — merlin2011, Jan 18 '20 at 02:16
I basically followed these instructions, and now sound and microphone are working. Many other things do not work on my X1C7 with Ubuntu 19.10, but at this point, I decided to wait for 20.04. and hope that everything will work out of the box. — Doc, Jan 19 '20 at 16:31
@Doc Thanks the the link to that thread - I hadn't seen it. However, even after manually walking through the script in the repo, and following the modifications recommended in the Lenovo thread, there is no change in my audio or microphone. In fact, my system was up-to-date with the result of the guide before I even started, besides using ${firmware_version} instead of a specific value. I'll upload my output of dmesg | grep sof to the original post. — jackson, Jan 20 '20 at 15:29
I upgraded to 20.04, installed all updates on the ubuntu software center (i.e., the firmware-updates), then followed steps 3-5 of this post, and the my mic worked, finally! :-) Note: That post also offers a solution for Ubuntu 19.10!

I had the same issue as you, here is what worked for me:

Step 1: Install the latest kernel available from kernel.ubuntu.com

Use ubuntu-mainline-kernel.sh to install the latest kernel available from kernel.ubuntu.com.

Step 2: Upgrade linux-firmware package to Ubuntu 20.04

Download and install Ubuntu 20.04’s linux-firmware package, which is currently at version 1.187.

Step 3: Blacklist snd_hda_intel and snd_soc_skl

Add the following lines to /etc/modprobe.d/blacklist.conf:

blacklist snd_hda_intel
blacklist snd_soc_skl

Step 4: Update PulseAudio config Add the following lines to /etc/pulse/default.pa:

load-module module-alsa-sink device=hw:0,0 channels=4
load-module module-alsa-source device=hw:0,7 channels=4

Step 5: Reboot

Reboot and make sure you boot with the kernel installed in step 1.

This did the trick on my Lenovo IdeaPad 5 14IIL05. Thank you so much, I was looking for ages and upgraded to the latest kernel and Ubuntu version. — Juergen, Aug 08 '20 at 10:09
With regard to step 1, can you be much more specific. How does one install the latest kernel. step-by-step instruction would be wonderful. — Michael Levy, Dec 30 '20 at 15:55
THANK YOU! This fixed my T14 Gen 2 on 22.04. I tried everything, but this worked. — Alan, Dec 07 '23 at 03:15

If you use Ubuntu 20.04 all these issues are fixed.

How does this not provide an answer? – pwaterz Apr 17 '20 at 21:02
You are not suggestion a solution to the problem, just to install some other version of Ubuntu. Its like "he, install CentOS, the problem does not exist there" – Simon Sudler Apr 19 '20 at 06:57
@pwaterz - Suggesting a different ubuntu version is not a solution for a 19.10-specific question, but suggesting a different kernel may be a solution, as suggested in the other answer. 20.04 has the new kernel too. – cipricus Apr 21 '20 at 07:15

I think that's totally open to interpretation. I personally think it would be WAY easier to solve the problem by updating version. If I came to this thread and saw that someone said things were better in a newer version I would update. There are plenty of times in software where the fix is to download an updated version because bugs were fixed. I stand by my answer. Telling folks to update their kernel is far more complicated and risky than just updating the whole OS. – pwaterz Apr 21 '20 at 16:29
