| Subject | Low audio in recorded videos with desktop screen recorders. |
| Message-ID | <p4CdnS62t96zcPTBnZ2dnUU7-I3NnZ2d@earthlink.com> |
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. :)

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. 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?

Many players like VLC, MPC-HC, etc. on multiple computers when I try to play the
recordings back.

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

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.

I forgot to share my http://screenshot.cz/F5/F55QQ/audiomixers.gif
screen capture if it helps.
