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.

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.
Many players like VLC, MPC-HC, etc. on multiple computers when I try to play the
recordings back.
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.
Hmm, maybe that's why:
$ dpkg -l |grep pulseaudio
ii gstreamer0.10-pulseaudio:amd64 0.10.31-3+nmu4+deb8u2 amd64 GStreamer plugin for PulseAudio
ii gstreamer1.0-pulseaudio:amd64 1.4.4-2+deb8u3 amd64 GStreamer plugin for PulseAudio
ii pulseaudio 5.0-13 amd64 PulseAudio sound server
ii pulseaudio-esound-compat 5.0-13 amd64 PulseAudio ESD compatibility layer
ii pulseaudio-module-x11 5.0-13 amd64 X11 module for PulseAudio sound server
ii pulseaudio-utils 5.0-13 amd64 Command line tools for the PulseAudio sound server
The other issue is, are you actually recording the videos with a sensible audio level for playback?
Yes. When I just do my normal playing, it is fine. It's just my recordings' audio
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.
