have you checked if your sound card's IGain is muted or set to a very low
level? Here I can set "Line" as capture device but the recording level is
determined only by the setting of "IGain". These things may differ from
card to card though, so I'd recommend to use alsamixer or the gui-mixer of
your choice to check the settings of the other mixer lines.
Pulse audio sits on top of alsa. Use alsamixer to select the sound
source (f6) and check that the input is not muted. If you see 'mm' it is
muted so hit the 'm' key to unmute it ( you should see '00') then raise
it's volume level to max using the up-arrow key. Hit 'esc' to exit. Then
use pavucontrol open the 'configuration' tab then select the sound
device. If it has stereo speakers then select stereo plus analog mono
input. Check the input devices tab to select your desired input device.
Leave this open and started your graphical recording app. Start
recording and check the recoding tab on pavucontrol. You should see the
audio level flickering.
Keep in mind that this is how stock audio is installed to Debian. If you
are following ten year old alsa setups of config files from the net, you
will be stuck and virtually punching alsa repeatedly in the face. Using
pulse you can have many sound input devices and you can select between
them on the fly.
I have five sound devices and I use pavucontrol to disable three of them
leaving my USB 7.1 sound system to be output only and my USB headphones
to be stereo and analog mono input. Click click, dead simple. Again, if
alsamixer isn't set correctly, pulse doesn't stand a chance. Ric
