Low audio in recorded videos with desktop screen recorders.

It seems like other Internet posters and I have problems with (e.g., Vokoscreen and
Kazam for me) screen recorders' video recordings having low audio volume than what I
hear during my simple video recordings. I am using an over decade old Debian Jessie
v8/oldstable desktop PC that uses an Intel onboard sound.
http://zimage.com/~ant/antfarm/about/MyComputerStuff.txt for the secondary PC's
details. I tried changing so many mixer volumes in ALSA, Pulse Audio, etc. in KDE
v4. It's confusing! My recorded videos' audioa are always low.
Has anyone had this problem and know how to fix it? Or do I have to use my decade
old, updated 64-bit W7 HPE SP1 PC to do the video recordings. :(
Thank you for reading and hopefully answering. :)

You should only change one thing at a time.
And in order to track down the problem, the following points must be
addressed:
1) Which application are you using to playback videos? Some applications
have their own volume control which can sometimes (eg mplayer) be difficult
to find how to adjust.
2) Are you running pulseaudio? If so, when you fire up pavucontrol and
go to the "Playback" tab (the first tab in fact), do you see in addition
to System Sounds, your application name and a volume control slider?
3) If you fire up alsamixer, does it show pulseaudio as the first (default)
device with volume control? The hitting F6, can you select the sound card
device for your Intel onboard output. Warning, on changing the alsamixer
volume control for the real sound card hardware device, some older pulseaudio
setups had a habit of resetting the level by themselves, so attempting to
change it manually actually served no purpose.
Old versions of pulseaudio at times had major problems messing with
sound levels and upgrading to a recent version (8.0 at least) would be
a sensible course of action.
The other issue is, are you actually recording the videos with a sensible
audio level for playback?

volume isn't.
Now, the bad news. I lost the audio completely in my recordings. Argh. I need to
figure how to get it back even if it is low.
