For all of you whose problem hasn't been solved, and whose sound input
cannot be detected by pulseaudio yet, I think I have the solution.
NULL SOUND INPUT
1. Install [audacity]
2. Go to [preferences/devices] and select your sound card from the combobox under the [Recording] section.
NOTE: I have [ALSA] in the [Interface] section, [default] in the [Playback] section and [HDA Intel: ...] in the [Recording] section.
3. Back in the main window, play around with the microphone combobox and record until you get the right microphone (you replay what you recorded to see if you were successful)
NOTE: [Digital Mic:0] worked for me just fine.
4. Install [padevchooser] (PulseAudio Device Chooser) and open it. You will see an applet in your panel.
5. From its menu, select [Manager...]. Now go to the [Devices] tab and select your input source. Then click on [Properties] button.
NOTE: My input source's name is [alsa_input.pci-0000_00_1b.0.analog-stereo].
6. Click on [Show Volume Meter]. Here you are supposed to record as you did with [audacity], now that [audacity] sets the mic for pulse.
QUIET SOUND INPUT
1. (Follow last guide from step #4).
2. Play with the [Volume] slider until you have decent settings.
NOTE: I have my slider at 200%.
LETTING GSTREAMER ENJOY THE GLORY
1. Run [gstreamer-properties].
2. Select [PulseAudio Sound Server] as your default input.
NOTE: I have [Default] as my [Device]. There are two other devices labeled as [Unknown]. One is the same as [Default] (the mic) and the other one is the default output. Use this second one when you want to record what your computer plays.
If this guide worked for you, feel free to come by to #ubuntu at irc.freenode.net and say hi to mezquitale and wolter. But mezquitale is the real mage here. He helped me out and gave me the audacity technique.
