Hello, e-group!
I have read that it is possible to add a pre-amp (pre-amplifier) to Alsamixer in order to boost/increase/amplify the default maximum volume of 100% so as to, obviously, go over 100% in volume. Unfortunately, I haven't been able to achieve this. Thus, does anybody of you know how to do this in Puppy Linux? I am using Puppy Linux 4.3.2 (based on 4.3.1).
On a related note, I have also read that increasing volume is also possible with PulseAudio, but it appears that going the Alsamixer route is easier. So please let's try Alsamixer first....though, as last resort, I wouldn't disregard PulseAudio.

Flash, this is actually possible, even system-wide. A pre-amp to Alsamixer or a configuration on PulseAudio do the trick, at least this has been reported, though on other distros and not on Puppy Linux. The problem arises when one has a sound file (or video file for that matter) that is too low even at full 100% volume level. Of course, normalization and stuff can be applied, but adding a pre-amp to Alsamixer is easier and faster, at least as a temporary solution.
Now that I think about it, please let me give you one of the links dealing with this pre-amp issue:

Do you know how to do this on Puppy Linux? I tried, but I was unsuccessful.

Bingo!
I was finally able to add a script (mentioned on the link of a previous post) and install a pre-amp to alsamixer, and everything works as intended. Even so, I am not really convinced of the real value of this pre-amp. While the audio files that were low now have a louder sound becoming sort of "normal", this has introduced clipping to the audio files that had a normal volume beforehand. I have played a little bit with different parameters, but I still haven't been able to find the "sweet spot" by virtue of which most everything are supposed to be acceptable, and frankly, I don't know if it would be possible. One way or another, I will report back once I take a final decision.
For the interests of those who might benefit with it, here's how you do it in Puppy Linux:
First, open Geany (Menu -> Document -> Geany text editor). Then, add the following:
pcm.!default {
type plug
slave.pcm "softvol"
}
pcm.softvol {
type softvol
slave {
pcm "dmix"
}
control {
name "Pre-Amp"
card 0
}
min_dB -5.0
max_dB 20.0
resolution 6
}
Afterwards, save this script, name it asound.conf , and place it inside the etc directory (click on the File icon on desktop and look for etc folder). Next, re-start the Alsa sound wizard (Menu -> Setup -> Alsa sound Wizard) and follow instructions. Finally, to see the new pre-amp, open Alsamixer (Menu -> Multimedia -> Alsamixer audio mixer). And to control it, use the right arrow key on your keyboard and, once on the pre-amp, use the up or down arrow keys to change values.

Hi, again! I have decided to use VLC as such can control volume up to 200% and can be used with specific files only and not system-wide. Notwithstanding, for those of you who, for instance, have an overall low volume as is the case with some laptops, I am sure that adding a pre-amp to alsamixer could be indeed useful.
