Microphone doesn't work (Thinkpad E14 Gen6 AMD)

felipebsd · Jun 2, 2025

Hello there!

The Thinkpad E14 Gen6 AMD is almost perfect for a complete FreeBSD (14.3) desktop experience, except for microphone. Even the camera works!

The device is reconized:

# cat /dev/sndstat
Installed devices:
pcm0: <ATI R6xx (HDMI)> (play)
pcm1: <ATI R6xx (HDMI)> (play)
pcm2: <ATI R6xx (HDMI)> (play)
pcm3: <Conexant (0x1f86) (Analog)> (play/rec) default
pcm4: <Conexant (0x1f86) (Left Analog Headphones)> (play)
No devices installed from userspace.

# mixer
pcm3:mixer: <Conexant (0x1f86) (Analog)> on hdaa1 (play/rec) (default)
vol = 1.00:1.00 pbk
pcm = 1.00:1.00 pbk
speaker = 1.00:1.00 pbk
mic = 1.00:1.00 rec src
rec = 1.00:1.00 pbk
ogain = 1.00:1.00 pbk

Loading the acpi_ibm.ko I can control the microphone led:

# sysctl dev.acpi_ibm.0.mic_led=1

But nothing is recording, It's like hardware mute.

Someone with more experience in this situation can help me?

Thanks

Is the microphone used the built-in or a external plugged-in? How did you test the microphone?

Test:

Code:

ffmpeg -thread_queue_size 1024 -f oss -i /dev/dsp3 test.m4a

dsp3 internal mic device.

I'm on a ThinkPad E15 AMD Gen 3 (the pindump example from post # 2 is from that machine), the microphone (recording) from internal mic works fine here with the above test.

felipebsd · Jun 3, 2025

It's the built-in.

Yes, I have tried before.

Did you play the file with a media player?

There should be other /dev/dsp* devices, try those as well recording from.

I didn't pay attention earlier as I should have, but nid 25 looks like the headphones / mic port combo microphone pin configuration, not the built-in (“Jack” and ‘disconnected’ imply this):

There is no other ("Internal") "Mic" listed in the pindump.

Check BIOS/UEFI if there is an extra internal microphone on/off switch. On my E15 it's a single on/off slider for both, speaker and mic (Security -> I/O Port Access -> Integrated Audio).

Here is the same.

I'm afraid I've reached a dead end with my help. The "pindump" doesn't show another (internal) "Mic" which might suggest a driver problem, I don't know.

Have you tested recording on another OSs? There was a case with audio issues (speaker) on FreeBSD, assumed resolved by warm reboot from Linux (https://forums.freebsd.org/threads/...although-headphone-out-does.92565/post-645751).

Besides trying that, you could check on 14.2 (in case there is a regression) and CURRENT if the pindump shows a Mic Fixed Digital Internal nid pin configuration.

If the tests don't show a internal mic on those versions as well, ask on the https://lists.freebsd.org/subscription/freebsd-multimedia mailing list, or -questions@, -current@. The FreeBSD developers there may have a better view of the problem.

If you have an external microphone or headset, you can at least test the functionality of the headphone / mic port, see is the mic is working there.

felipebsd · Jun 6, 2025

I tried in the Linux livecd (Ubuntu Desktop 25.04) and works like a charmy over there.

I will keep trying until I find a workable solution and will update here if I find one.

Thanks for your time.
