darkice doesn't accept pulseaudio input

[STrRedWolf]

Darkice on Ubuntu does not accept pulseaudio input. It thinks it's an ALSA input, and fails to open it.

This is a compile configuration bug, since I can compile it with pulseaudio input on Gentoo and works flawlessly -- it picks up the audio from PulseAudio (in this case input from an iPad 4 being sent via Bluetooth, thus th need for PulseAudio) and sends it to Icecast 2 on a Debian ARM system.

Package version: 1.0-1ubuntu1

I confirm this. I am on a Dell Inspiron N5110, everything works well with Lubuntu 14.04 fresh install.
I also installed audacity pulse, pavucontrol.

By default alsa records my integrated microphone only, by playing with pavu i was able to record the pulse loopback.

I also see audacity when i am recording, on pavucontroland i was able to change the source on it like many tutorials suggest.

With darkice i can on record my microphone on alsa loopback.

I use the following config: in /etc/darkice.cfg

[general]
duration=0
bufferSecs=1
reconnect=yes

[input]
#device=default
device = pulse # OSS DSP soundcard device for the audio input
#paSourceName = alsa_input.pci-0000_00_1b.0.analog-stereo
sampleRate = 44100
bitsPerSample = 16
channel = 2

[icecast2-0]
bitrateMode=vbr
quality=1.0
format=mp3
server=localhost
port=8000
password=hackme
mountPoint=radio1
name=mawebradio
description=Une super radio...
url=http://mawebradio.fr
genre=hardcore

The result when i launch sudo darkice is:

$ sudo darkice

I used the default repo packages (sudo apt-get install icecast2 darkice ...)

With this working i could stream my music form my laptop to my windows phone linked to my stereo ^^

Status changed to 'Confirmed' because the bug affects multiple users.

I found a way to make it work:
$ darkice

If i run darkice in sudo mode it doesn't work, so just run darkice with device=pulse like
[input]
#device=default
device = pulse # OSS DSP soundcard device for the audio input
#paSourceName = alsa_input.pci-0000_00_1b.0.analog-stereo
sampleRate = 44100
bitsPerSample = 16
channel = 2

and it works.

A tip for anyone getting here:

if you type : pactl load-module module-null-sink sink_name=anyname

it makes a new device "Moitor of someting" in pavu, and you can make a program play on that chanel and then make darkice record on that channel so the sound played by default programs aren't recorded.
