Microphone Detected but no Input

Hello,

I've got a simple Zalman ZM-Mic1 microphone with a 3.5mm phone jack connecter and trying since hours to get it working. I followed the https://wiki.archlinux.org/index.php/Pu … Microphone steps but with no luck.

I can see my microphone on pavucontrol under input devices. It correctly detects that microphone is plugged in or not (showing Rear Microphone (plugged in) for the port).
Under alsamixer I selected my Card HD-Audio Generic then selected the Rear Mic (where my microphone is plugged in) as the input source and increased the Rear Mic Boost to 50.
I uncommented the line load-module module-alsa-source device=hw:1,0 in /etc/pulse/default.pa as mentioned in the wiki above.

There is simply no input. Detection of the microphone works perfectly though. Plugging it in and out of the ports is correctly detected. When I plug it into the front connection it correctly detects that it's the front port.
The microphone is not broken. It works perfectly fine on Windows 10 on the same machine and same port.

Here is the output for pacmd list-sources

I tried to explicitly set my input device by 

pacmd set-source-port alsa_input.pci-0000_0c_00.3.analog-stereo analog-input-rear-mic

Recording input only results in pure silence

arecord -f cd -d 10 -r 48000 test-mic.wav

Re: Microphone Detected but no Input

You are not recording anything in these outputs, or if you do, you are accessing an incorrect ALSA device and not the pulse sink.

Try 

parec --file-format=wav --device=alsa_input.pci-0000_0c_00.3.analog-stereo testing.wav #While this is running post the next ones
pacmd list-sources
pacmd list-source-outputs
sudo fuser -v /dev/snd/*
amixer -c1
systool -vm snd_hda_intel
uname -a

Re: Microphone Detected but no Input

While running  

parec --file-format=wav --device=alsa_input.pci-0000_0c_00.3.analog-stereo testing.wav

in one terminal, I ran the other commands in another one:

Re: Microphone Detected but no Input

Looks alright, was the testing.wav silent as well? Those panel controls detected by amixer look relevant, try 

amixer -c1 set 'Rear-Panel',0 60,60
amixer -c1 set 'Rear Mic Boost',0 0,0 #Just a precaution, you may omit this, however having mic boosts at full blast usually just leads to noise
amixer -c1 set 'Capture',1 60,60 #No clue how relevant this one is and it seems quite disjoint from the rest, but it's there and it's muted so it might be relevant.
#Retry the steps again (systool and uname aren't needed anymore, these were just to check some general things, the others you might still do)
#If it still doesn't work, try raw hardware access on the detected captures
arecord -Dhw:1,0 -f cd -d 10 -r 48000 test-mic0.wav
arecord -Dhw:1,2 -f cd -d 10 -r 48000 test-mic2.wav
arecord -Dhw:1,4 -f cd -d 10 -r 48000 test-mic4.wav

Re: Microphone Detected but no Input

The testing.wav was silent.

Here's the output:

$ amixer -c1 set 'Rear-Panel',0 60,60
Simple mixer control 'Rear-Panel',0
  Capabilities: cvolume cswitch
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 63
  Front Left: Capture 60 [95%] [27.75dB] [off]
  Front Right: Capture 60 [95%] [27.75dB] [off]

$ amixer -c1 set 'Rear Mic Boost',0 0,0
Simple mixer control 'Rear Mic Boost',0
  Capabilities: volume
  Playback channels: Front Left - Front Right
  Capture channels: Front Left - Front Right
  Limits: 0 - 3
  Front Left: 0 [0%] [0.00dB]
  Front Right: 0 [0%] [0.00dB]

$ amixer -c1 set 'Capture',1 60,60
Simple mixer control 'Capture',1
  Capabilities: cvolume cswitch
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 63
  Front Left: Capture 60 [95%] [27.75dB] [off]
  Front Right: Capture 60 [95%] [27.75dB] [off]

Then I exectued again

$ parec --file-format=wav --device=alsa_input.pci-0000_0c_00.3.analog-stereo testing.wav

An ran again

Unfortunately the testing.wav was again silent. So I tried

$ arecord -Dhw:1,0 -f cd -d 10 -r 48000 test-mic0.wav
arecord: main:828: audio open error: Device or resource busy

$ arecord -Dhw:1,2 -f cd -d 10 -r 48000 test-mic2.wav
Recording WAVE 'test-mic2.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

$ arecord -Dhw:1,4 -f cd -d 10 -r 48000 test-mic4.wav
Recording WAVE 'test-mic4.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

The recording from the first capture device failed and the other .wav files were silent.

Re: Microphone Detected but no Input

Final solution was to buy a USB microphone.
