SubjectSound input source detected but not capturing
Message-ID<CTlaN-8kU-7@gated-at.bofh.it>
I have a fresh Bullseye installation on a laptop. Sound output is
working. But the input is not working. The device is detected.

--8<---------------cut here---------------start------------->8---
$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC236 Analog [ALC236 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
--8<---------------cut here---------------end--------------->8---

In the gnome settings, input is showing built-in microphone but there is
not movement in the capturing indicator.

alsamixer is also showing the sound card (F6) - HDA Intel PCH.

Did you make sure:

1. correct device is set to record from 
2. recording is enabled
3. input volume is large enough

If you are not sure send the output of command 'amixer' so we can check.

In fact, unless you have only one sound device, the command should
be 'amixer -cN' where N is the number of your sound card and can change
after reboot. So first you have to type 'cat /proc/asound/cards' to
find your card number.

I guess I have only one device so there is nothing to set.

How is recording enabled? Do I need to add myself to some group? I am
member of followin groups: pankaj cdrom floppy sudo audio dip video
plugdev netdev bluetooth scanner.

I have tried to set input volume using various knobs in gnome settings
as well as alsamixer. It did not work.

I meant 'input source'. On my machine it can be:

'Rear Mic' 'Front Mic' 'Line' 'CD'

You are member of audio group, so that's fine. By 'recording enabled I
meant on/off switch.

Your control 'Capture',0 is turned on and volume is at maximum, so
that's fine, but you don't have 'input source' control. On my machine
output of 'amixer -c0' gives among other controls the following:

Simple mixer control 'Input Source',0
  Capabilities: cenum
  Items: 'Rear Mic' 'Front Mic' 'Line' 'CD'
  Item0: 'Rear Mic'

I suppose this is the reason why your capture is not working, but don't
know how to fix it. You might try to install kernel 5.13 from
experimental or newest vanilla stable which is currently 5.14.1 (take
care not to make your system unbootable). Also you might try with newer
alsa userland software.

Hmm... I have returned from the macos world. I need to regain speed to
do all that. It has been a couple of years now. ;-)

Well, there's no "Internal Mic" and "Mic" to choose from, so maybe 
that's the problem.

@Pankaj, do you have a microphone connected to the audio (combo) jack 
and/or maybe the internal microphone is disabled in EFI and/or from 
hotkeys?

Or this...

Very new laptop? Does it need Intel firmware for the soundcard? 
firmware-intel-sound from non-free? 

https://packages.debian.org/bullseye/firmware-intel-sound

All the very best, as ever,

Thanks for the advice, Andy. I just tried it. But this did not work. I
even rebooted the system after installing. That did not make any
difference.

Had the same problem,

apt-get purge pipewire
apt-get --purge autoremove

did the job. According to several posts on this list, pipewire doesn't
seem to work properly. Unfortunately there was no changelog warning
when upgrading and pipewire's developers do not seem to care much about
documentation.
