OK.
You should have pulseaudio-utils installed - this package includes the
"parec" command used to record Pulseaudio sources.
You should also have Pulseaudio GUI applications under menu "Sound &
Video" "PulseAudio Volume Control" & "Pulse Audio Volume Meter
(Capture)"
First it is necessary to make sure you are getting audio on the correct
input and that you can record audio from the input.
Plug a sound source into the audio in and make there is continuous audio
(e.g a radio station)
Using "Pulse Audio Volume Meter (Capture)" - on the working port the
meters should be moving - find which pulse audio device is the one you
are using.
If No port show activity use "PulseAudio Volume Control" to look at
input devices and make sure volume level is right to show activity.
The command to record a WAV file form audio input is as follows.
Code:
--------------------
parec --file-format=wav -d alsa_input.pci-0000_00_1b.0.analog-stereo test.wav
--------------------
After record about 30 secs - stop the program and try to play the
test.wav file to confirm the audio has been recorded.
The input device (i.e. the devices start with "alsa_input") you use
will depend on your system. A short list of valid device names (Igore
any "monitor" devices) will be shown using
Code:
--------------------
pactl list short sources
--------------------
