[SOLVED] Microphone not working Thinkpad P53 (CX8070)

I did a fresh Arch install on a Thinkpad P53. There is an issue with audio input and I haven't managed to get it to work yet. Output works fine using the internal speakers and also when plugging in an audio headset. All the alsa packages are installed (alsa-utils, alsa-firmware) as well as pulseaudio (which I want to use). In pavucontrol I configured the Built-In Audio as "Analog Stereo Duplex" but there is no microphone input at all.

According to this: https://wiki.archlinux.org/title/Advanc … ot_working I created the config file, but no success.
This is the line:

options snd-hda-intel enable_msi=1

Any ideas how I can get microphone input to work? Any hints are appreciated smile

Edit - Found the problem:
The microphone was disabled in BIOS. Enabling it made it work.

https://unix.stackexchange.com/question … -archlinux

The input device is not muted in pavucontrol. There is the "Built-in Audio Analog Stereo" which is set to "Analog Input" and 100 %. But the bar which indicates audio input shows nothing. Testing with arecord also gives no input, just stays silent. What seems odd to me is that in alsamixer for the HDA Intel PCH card I only see one Capture device "Digital" (set to 100). I would expect something like "Internal Microphone" there.

Re: [SOLVED] Microphone not working Thinkpad P53 (CX8070)

Yes. Still didn't work. Had to force unload the module though as pulseaudio was always using it and I couldn't get it to reload otherwise.

This post suggests lowering the volume having success:

This also didn't have any effect.

Re: [SOLVED] Microphone not working Thinkpad P53 (CX8070)

I have one more with with some ideas :
https://bbs.archlinux.org/viewtopic.php?id=257121

I tried using the sof-firmware, but it doesn't change anything. After installing it I still get the same devices in alsamixer and no working mic. And installing it should be all that needs to be done to use it, as far as I understand (I removed all other sound configs from /etc/modprobe.d). However in dmesg I don't have any sof related messages as mentioned in the wiki:

sof-firmware is required for some newer laptop models (mainly since 2019) because they implement their drivers with firmware provided by the Sound Open Firmware project. Checking the journal will provide messages about the missing firmware (see BBS#275577).

So yeah, I'm still a bit stuck on this one.

Re: [SOLVED] Microphone not working Thinkpad P53 (CX8070)

After some more reading and checking my hardware again I found that the wiki says Intel Cannon Lake CPUs might require some special settings:

lspci | grep -i Audio

00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10)
01:00.1 Audio device: NVIDIA Corporation TU106 High Definition Audio Controller (rev a1)

On Intel Cannon Lake (eg. HP ZBook 15 G6), the integrated sound chipset requires ALSA firmware, and the following kernel module parameters are required:

options snd-hda-intel dmic_detect=0
options snd-hda-intel model=laptop-amic enable=yes

That should enable both sound and microphone.

This seems like it should solve my problem, however I still don't get any input in the microphone. I tried it with sof-firmware and without (I'm still not sure whether I should/can use it or not). This reddit post: https://www.reddit.com/r/Gentoo/comment … enovo_e14/ suggests that my codec (Conexant CX8070) would work with it. However even after installing it my card still shows up like this:

cat /proc/asound/cards

 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0x6041108000 irq 183

Re: [SOLVED] Microphone not working Thinkpad P53 (CX8070)

Disregard most of that, drop the modprobe conf if you still have that, and reboot, so we get the state from your OP.

You have a "two channel" microphone. That's very often a lie and will actually lead to breakage, try muting the left (or right) channel and try to record then, e.g. 

pactl set-source-volume alsa_input.pci-0000_00_1f.3.analog-stereo 100% 0
parecord -d alsa_input.pci-0000_00_1f.3.analog-stereo testLeft.wav
pactl set-source-volume alsa_input.pci-0000_00_1f.3.analog-stereo 0 100%
parecord -d alsa_input.pci-0000_00_1f.3.analog-stereo testRight.wav

Re: [SOLVED] Microphone not working Thinkpad P53 (CX8070)

I tried muting the channels but no success. The recording is totally silent, no static noise or anything. In alsamixer I noticed that the default Card (PulseAudio) shows the "Capture" device with two channels. But the HDA Intel PCH card only shows one capture device "Digital" with one single channel.

Re: [SOLVED] Microphone not working Thinkpad P53 (CX8070)

Update after some more reading. I had a look at the options for my codec on https://www.kernel.org/doc/html/latest/ … exant-5066 (my exact kernel is not there so I looked at some of the other Conexant codecs. headphone-mic-pin and stereo-dmic sounded like it would be worth giving them a try. Especially because I also found this post where microphone issues got resolved after setting headphone-mic-pin: https://askubuntu.com/a/1307597.

Unfortunately none of them worked and I am still stuck with non-working microphone. Slowly running a bit out of ideas.

Finally I solved this: The microphone was disabled in BIOS. Enabling it fixed it, immediately worked after that!
