[Bug 1395501] Re: input devices found, but there is no input level
This is now solved.

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".

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!
