There is the continuing problem of built-in speakers on laptops
being too quiet when running Linux. I managed to fix this with
something in /etc/asound.conf and an extra mate-volume-control
applet added to the panel. With this extra volume control, I was
able to turn the audio far past 100% and even past 153%. The
laptop I'm working on needed to be wiped and the OS reinstalled.
Unfortunately I neglected to save or write down what I did to
implement this volume control tweak.
Before I discovered this, I used /etc/asound.conf (or ~/.asoundrc)
to add a "Pre-Amp" slider to Alsa. This raises up the low end such
that the really quiet audio stuff is loud enough. I'm not sure if
that had anything to do with the volume control tweak.
Would someone please help me with figuring out what I could have
possibly done to make MATE's audio control applet to go as far past
100% as I cared to raise it?
Do you have access to the MATE Control Center, through the
applications menu?
If so, in there, is the Hardware -> Sound settings configurator
Also, in System -> Preferences -> Hardware -> Sound
Whilst this is on a UbuntuMATE system, I expect that you should, if
you are using the MATE desktop environment, have access the same
way, to the same functionalities.
I'm on a regular Debian system. What you pointed me to is the same
thing that I get if I right-click on the volume control applet and
select "sound preferences". I'm not clear on what I'm supposed to
see there as it has no visible options to raise the maximum volume.
