PulseAudio doesn't detect webcam's microphone

I'm using Skype to keep in touch with my friends, and as I tried it yesterday with a webcam integrated in my laptop, nobody could hear me - the microphone didn't work. I tried recording something with audacity - it gives me 4 input options: pulse, HDA Intel PCH: ALC665 Analog, defaut and sysdefault. When I choose pulse, nothing gets recorded, when I choose HDA Intel, everything works as expected. Pavucontrol shows me only a "Monitor of built-in analog sound", which doesn't work. I followed the advice on PulseAudio/Troubleshooting wiki page:

 kolzi@kolzi-laptop ~ % arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC665 Analog [ALC665 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

and added

load-module module-alsa-source device=hw:0,0 

to my /etc/pulse/default.pa, above the line saying

.ifexists module-udev-detect.so
load-module module-udev-detect

It kind of worked - finally my microphone showed up in pulseaudio, I could observe the volume bars moving, but... all of my output devices were gone, everything that was left is null output device. I guess that by loading the module by hand, I disabled autodetection. How can I make it detect my microphone?

Re: PulseAudio doesn't detect webcam's microphone

reenable autodetection (comment out the module-alsa-source and restart pulseaudio

pulseaudio -k

) and then post

pacmd list-cards
pacmd list-sources

I just want to check if your microphone really actually isn't detected or if you've missed something

Something is detected - but that's the monitor thing that doesn't work. I guess it'll be for some stupid reason, but I can't figure it out...

@PL_kolek, I'm having the same problem. Did you eventually resolved this?

Re: PulseAudio doesn't detect webcam's microphone

@Demon please open a new thread, with the information I requested in the second post, or see if the following clears it up.

@PL_kolek if for some reason you are still looking for a solution, your pulseaudio profile is wrong, it should be output:analog-stereo+input:analog-stereo, switch that in pavucontrol's configuration tab and check if it works.
