Output sound working but no input

[Neblinus]

Good afternoon!!
After many years of Linux, I have finally switched to FreeBSD 14.3-RELEASE with GENERIC kernel, amd64.

So far being a good ride, already solved some problems I had on my own (thanks Linux for the training wheels LOL), but there's one little thing:
I have set the sound card and sound output its alright, but I can't get my laptop internal microphone to work.

Here's some information from cat /dev/sndstat

Installed devices:
pcm0: <Realtek ALC272 (Analog 2.0+HP/2.0)> (play/rec) default
pcm1: <Realtek ALC272 (Left Analog Mic)> (rec)
pcm2: <Intel Ibex Peak (HDMI/DP 8ch)> (play)
No devices installed from userspace.

Information from mixer -f /dev/mixer0 (the speaker)

pcm0:mixer: <Realtek ALC272 (Analog 2.0+HP/2.0)> on hdaa0 (play/rec) (default)
    vol       = 1.00:1.00     pbk
    pcm       = 1.00:1.00     pbk
    speaker   = 1.00:1.00     rec
    mix       = 0.74:0.74     rec
    rec       = 1.00:1.00     pbk
    igain     = 1.00:1.00     pbk
    ogain     = 1.00:1.00     pbk
    monitor   = 0.67:0.67     rec src

And information from mixer -f /dev/mixer1 (the microphone)

pcm1:mixer: <Realtek ALC272 (Left Analog Mic)> on hdaa0 (rec)
    speaker   = 0.00:0.00     rec
    mic       = 1.00:1.00     rec src
    rec       = 0.91:0.91     pbk

As per indicated by the Handbook, I have snd_driver_load="YES" defined on /boot/loader.conf loaded at boot time.

I also have hw.snd.default_unit=0 defined on /etc/sysctl.conf, also indicated by the Handbook.

After some research, I was able to grasp some understanding that this line:
speaker = 0.00:0.00 rec
of mixer -f /dev/mixer1 output (for the microphone)

pcm1:mixer: <Realtek ALC272 (Left Analog Mic)> on hdaa0 (rec)
    speaker   = 0.00:0.00     rec
    mic       = 1.00:1.00     rec src
    rec       = 0.91:0.91     pbk

indicates that its volume is set to 0.

So, I tried to set it with mixer -f /dev/mixer1 speaker=1.0, but this gave me (perhaps the most insightful?) output:

mixer: speaker.volume=1.00:1.00: Device not configured
pcm1:mixer: <Realtek ALC272 (Left Analog Mic)> on hdaa0 (rec)
    speaker   = 0.00:0.00     rec
    mic       = 1.00:1.00     rec src
    rec       = 0.91:0.91     pbk

Searching on the internet gave very few results, even considering both Google and DuckDuckGo results...
Can anyone help me out?

As per indicated by the Handbook, I have snd_driver_load="YES" defined on /boot/loader.conf loaded at boot time.

You don't need to load snd_driver necessarily, the audio card is detected automatically in most cases.

I also have hw.snd.default_unit=0 defined on /etc/sysctl.conf

With default_unit=0, the microphone is configured on pcm0 (note "(play/rec)")

pcm0:mixer: <Realtek ALC272 (Analog 2.0+HP/2.0)> on hdaa0 (play/rec) (default)

Try to record something:

ffmpeg -f oss -i /dev/dsp3  test.mp3

If ffmpeg complains about dsp3, try another device.

about dsp3

I believe T-Daemon went away for a second and meant dsp1.

Hello!!
Thanks for answering!!

You don't need to load snd_driver necessarily, the audio card is detected automatically in most cases.

In fact, the Handbook even states this, but I tried it to see if the microphone would work.
I will remove it from the conf file.

With default_unit=0, the microphone is configured on pcm0 (note "(play/rec)")

Yeah, I also realized this, but I thought if I set it to the microphone ( default_unit=1) the output device default_unit=0 would be left non-working. Guess I'm just dumb LOL.

Try to record something:

I will!!
Right now I can't, but I will be doing so in approximately 1/2 hours.
I will then come back with the results and possible the fix, if I get it.

Thank you so much for you time and help!!

Hello!!
Thanks for the attention!!

As I replied to T-Daemon, I will be soon testing this.
Thank you so much for the hint!!

Hello!!
So, I tried setting the mic as default with sysctl hw.snd.default_unit=1, and after that, executing mixer -f /dev/mixer1 speaker=1.0, but still no luck:

mixer: speaker.volume=1.00:1.00: Device not configured
pcm1:mixer: <Realtek ALC272 (Left Analog Mic)> on hdaa0 (rec) (default)
    speaker   = 0.00:0.00     rec
    mic       = 1.00:1.00     rec src
    rec       = 0.91:0.91     pbk

Try to record something:

I tried recording as you indicated (and as W.hâ/t pointed out) using ffmpeg -f oss -i /dev/dsp1 test.mp3.
The resulting file was correctly saved, but the sound...I only hear static.

In fact, if I get near the spot where sound is outputted, I can hear a little static that is constant.

I then tried using the sound output device, as according to mixer, it has also recording capabilities:

pcm0:mixer: <Realtek ALC272 (Analog 2.0+HP/2.0)> on hdaa0 (play/rec) (default)
    vol       = 1.00:1.00     pbk
    pcm       = 1.00:1.00     pbk
    speaker   = 1.00:1.00     rec
    mix       = 0.74:0.74     rec
    rec       = 1.00:1.00     pbk
    igain     = 1.00:1.00     pbk
    ogain     = 1.00:1.00     pbk
    monitor   = 0.67:0.67     rec src

I set it as the default sysctl hw.snd.default_unit=0 and then, using ffmpeg -f oss -i /dev/dsp0 test.mp3, I was able to record something and actually hear my voice on top of a very loud static.

I tested again, still using the ouput device, but this time with the microphone turned off from Xfce media controls ( xfce4-pulseaudio-plugin).

Even then, I could record, hear my voice, but still on top of a very loud static.

What's interesting is that I was able to actually join a meeting on Google Meet using this laptop, with the microphone set to the output device ( pcm0:mixer: <Realtek ALC272 (Analog 2.0+HP/2.0)> on hdaa0 (play/rec) (default) both on Meet and on Xfce plugin, and everyone could hear me perfectly, without static.


EDIT:
Even more interesting found:
Adjusting the PulseAudio plugin of the microphone icon to 0 (without turning the toggle off), with the microphone set to the output device (still at the plugin) stops the static I could hear near the laptop completely, but also makes no sound on the recording.

 

[js-denton]

I have same problem. On my laptop the audio is ALC257. Speaker was detected - no problem, but internal microphone don't detected, only microphone via mini jack.

I don't understan how setting device.hints
My laptop is IdeaPad 5 14IIL05.
I don't understand why show double audio mixer and why have three spekers.
Output mixer:

pcm0:mixer: <Realtek ALC257 (Analog 2.0+HP/2.0)> on hdaa0 (play/rec) (default)
    vol       = 0.52:0.52     pbk
    pcm       = 1.00:1.00     pbk
    speaker   = 1.00:1.00     rec
    mic       = 0.94:0.94     rec src
    rec       = 0.37:0.37     pbk
    ogain     = 1.00:1.00     pbk

I try mixer mic.recsrc=add speaker.recsrc=remove, but nothing changes.
If i connect headphone with microphone - all works correct. In Audacity display 4 devices:
/dev/dsp: Spkr
/dev/dsp: Mic
/dev/dsp0: Spkr
/dev/dsp0: Mic
Regardless of what I choose, the recording will only work with the microphone on the headset.

Anybody have ideas what to do?

Would you please provide dmesg | grep pcm0.

Sorry for the inconvenience, I forgot to mention this in my last post.

 

[js-denton]

Yes, of сourse:
js-denton@Zion:~ $ dmesg | grep pcm0

pcm0: <Realtek ALC257 (Analog 2.0+HP/2.0)> at nid 20,33 and 25 on hdaa0

But seems is not really different from /dev/sndstat

 

[T-Daemon]

But seems is not really different from /dev/sndstat

I needed the node ID's (nid 20,33 and 25), cat /dev/sndstat doesn't show them.

Try /boot/device.hints ("as" , "seq" values copied from my laptops Realtek ALC257 pindump):

hint.hdaa.0.nid25.config="as=3 seq=0"

To take effect, reboot system.

 

[js-denton]

Thanks for help, but no effect. Can this be related to the webcam? Maybe need to set up something there? I turned on the camera on handbook and there were no problems with it.

 

[christos]

js-denton In your pindump the microphone shows up as "Jack". Can you plug a headset with a microphone and see if it works?

Neblinus Can you share the output of dmesg after you run `sysctl dev.hdac.0.pindump=1`?

 

[kgbsd]

Just spent half the day troubleshooting very similar microphone issue, sound out is great, but no microphone on command line and no microphone in firefox.
figured I'd post my findings as this thread comes up in searches and will link other threads that have seemed to die to here.
will resort to using my bluetooth headset.
onboard laptop camera works good, no complains there except no one car hear me.

Turns out FreeBSD does not detect the internal microphone because there isn't a real one as I can tell, but this Array/Smart Sound:

I booted into Windows and device manager:

Audio Inputs:
  Microphone Array ("Intel Smart Sound Techology for Digital Microphones")
Sound, video and game controllers:
  "Intel Smart Sound Techology for Digital Microphones"

The ALC285 and ALC257 seems to be the same issue, FreeBSD does not see the microphone. It does however see the microphone jack [but I have no mic to plug in].

[js-denton]

js-denton In your pindump the microphone shows up as "Jack". Can you plug a headset with a microphone and see if it works?

Neblinus Can you share the output of dmesg after you run `sysctl dev.hdac.0.pindump=1`?

Yes, my headset it's worked. But now E is once hard freezed and then sound after short time is crached. I will try installed MidnightBSD and see what's there.
