My problem is that PulseAudio don't register input level from some of my input devices.
When I speak in my mic the input level in PulseAudio don't show any reaction!
They are not muted and volume is near 100%.

- These mic devices don't work:
Built-in mic give no input level (internal speakers output works fine).
External mic give no input level (external headseth output works fine).
USB Sennheiser 3D G4ME1 + Sennheiser PC 363D mic give no input level (headseth output works fine).

- These mic devices works fine:
USB Jabra Speak 510 mic gives input level (output also works fine).
USB Plantronics C720 mic gives input level (output also works fine).

seem only three pin complex

you have to use hda jack sense test to find out the missing mic jack

Tanks for the replies, Raymond (superquad-vortex2), but what do you want me to do now?

[Raymond (superquad-vortex2)]

http://voices.canonical.com/david.henningsson/2014/03/07/headset-jacks-on-newer-laptops/

do you computer support headset, headphone and conventional mic?

try mute right channel or record in stereo to check the signal of left and right are inverted

[Pål F. Kristiansen (paalfe)]

The computer support on jack with headseth with mic on the same jack.

Recording is done in stereo channel, tried muting left and the right, input level is still not shown in pulseaudio.

$ grep -r Realtek /proc/asound/card*
/proc/asound/card1/codec#0:Codec: Realtek ALC668

"options snd-hda-intel model=,dell-headset-multi" in /etc/modprobe.d/alsa-base.conf do not help. Autoswitch when connecting headseth works fine without dell-headset-multi option.

Ran "ubuntu-bug audio" to debug mic and it do record, but Pulseaudio do not show any reaction on input level monitor!

Did a record in Ocenaudio with built-in mic, it do record, but Pulseaudio do not show any reaction on input level monitor! Same happens for my Senheiser USB soundcard + headseth with mic.

So it turns out the input devices do record, but input level monitor in pulseaudio do not show any signal! Why does this only happens for my builtin mic, external mic and senheiser usb soundcard + headseth with mic. Everything works fine for my plantronics usb headseth with mic and my jabra speaker with mic!

http://bazaar.launchpad.net/~unity-settings-daemon-team/unity-settings-daemon/trunk/view/head:/plugins/media-keys/what-did-you-plug-in/pa-backend.c

the combo jack is setuo to support headphone, you need to change it to headset or mic by the popup dialog

[Raymond (superquad-vortex2)]

refer to pa_backend.c

did you find headset mic jack or headset mic phantom jack in codec info using dell headset model?

In PulseAudio ports will show up with the following names:
   Headphones - analog-output-headphones
   Headset mic - analog-input-microphone-headset
   Jack in mic-in mode - analog-input-microphone

   However, since regular mics also show up as analog-input-microphone,
   we need to check for certain controls on alsa mixer level too, to know
   if we deal with a separate mic jack, or a multi-function jack with a
   mic-in mode (also called "headphone mic").
   We check for the following names:

   Headphone Mic Jack - indicates headphone and mic-in mode share the same jack,
     i e, not two separate jacks. Hardware cannot distinguish between a
     headphone and a mic.
   Headset Mic Phantom Jack - indicates headset jack where hardware can not
     distinguish between headphones and headsets
   Headset Mic Jack - indicates headset jack where hardware can distinguish
     between headphones and headsets. There is no use popping up a dialog in
     this case, unless we already need to do this for the mic-in mode.

[Pål F. Kristiansen (paalfe)]

When I have enabled "options snd-hda-intel model=,dell-headset-multi" in /etc/modprobe.d/alsa-base.conf I do get the popup for choosing "Headphones", "Headset" and "Microphone".

And in PA on Built-in Audio Analog Stereo I get:
- Internal Microphone
- Headset Microphone
- Microphone

[Pål F. Kristiansen (paalfe)]

Still have problem with this.
What I don't understand is why this also happens with some of my external USB soundcards?

I also can't send audio to my audio receiver via HDMI. I can choose via HDMI, but audio receiver don't receive audio!

[Pål F. Kristiansen (paalfe)]

This problem is still not solved, I have no idea what to do next...

Here are some more info if it helps.

upgraded kernel to 3.16.0-30-generic.

Internal soundcard is now recognized as Realtek ALC3661, wich is correct.

$ grep -r Realtek /proc/asound/card*
/proc/asound/card1/codec#0:Codec: Realtek ALC3661

Still have problem with mic not working, happens to my internal mic, external mic and external usb-sound card.
The weird thing is that mic works fine if I boot PC from a Ubuntu 14.04.1 USB boot key.

[Pål F. Kristiansen (paalfe)]

This is now solved.

------ 1 ------
Headset jacks on newer laptops - http://voices.canonical.com/david.henningsson/2014/03/07/headset-jacks-on-newer-laptops/.

Solved by adding "options snd-hda-intel model=,dell-headset-multi" in "/etc/modprobe.d/alsa-base.conf".

------ 2 ------
Pulseaudio remixing was disabled.

I had disabled Pulseaudio remixing to avoid upmixing of stereo audio streams when using a multi-channel output (5.1 digital output).

Disabling Pulseaudio remixing gave problems when watching multi-channel movies in Totem or VLC and using stereo output. I only got audio from the front-left and front-right audio tracks, no audio from the center, back-left and back-right audio tracks.

I therefor re-enabled Pulseaudio and at the same time I noticed that all my mics suddenly worked fine again in Pulseadio!

Enable/disable Pulseaudio remixing is done in "/etc/pulse/daemon.conf", look for "enable-remixing". It is enabled by default!

---------------
So this was not a bug, it was configuration problems caused by myself!
