How to boost volume of unamplified speakers?
How to boost volume of unamplified speakers?
Hi my speakers are supposed to be plugged into another PC that has a built in amp
, that PC broke so I now plug the speakers straight into the soundcard but they are very quiet.
what i need is a way of boosting the volume to the whole OS (turn it up to 11)
when people talk on vent (mangler) i can boost their volume with a slider so its nice and loud, so I know its possible

As far as I know, the speaker output of all motherboards is very low power, requiring amplification before it will drive speakers with enough power to be heard. Sound cards also generally require their output to be amplified.
Slenkar, if you still have that old computer, the card where the speakers were plugged in may be still good. It must contain an amplifier. You should be able to move it to the new computer. Otherwise, you'll have to either get a sound card that has an amplifier, an external amplifier for the speakers or new speakers with a built-in amplifier.

The first computer I bought had a Winmodem in it. Apparently those things have amplifiers that are powerful enough to double as the output amplifier for the speakers. Unfortunately everything in a Winmodem is done in software, so you can't use them in Linux for the audio amplifier. So I had to buy speakers with built-in amplifiers. Too bad, because H-P had done a good job of matching the speakers to the amp. They really sounded good.
I managed to get a pre-amp on my retrovol by adding a script as said here:

I installed a fresh precise and now when I try to do it the sound system crashes.

create /etc/asound.conf
and paste this:
Then you get PreAmp in retrovol
and paste this:

Then you get PreAmp in retrovol
Tested in X-precise 2.2 (Precise 5.6.1 based, xfce4-mixer), Carolite 1.1 (Racy 5.2.2 based, xfce4-mixer), and LxPup 13.10c (Slacko 5.6 based, retrovol mixer). Worked great in X-Precise and Carolite with the xfce4-mixer. Preamp control shows up and works. In LxPup, using retrovol, I haven't yet gotten the preamp control to show up. Rebooted, tried both type hw and type plug in the conf file etc. Also played with alsamixer with no sucess yet so I'm batting .666 here. Not too bad My guess is that it would also work on X-Slacko 1.1, also with the xfce4 mixer, but don't have that on board right now.
All of the above on a Fujitsu S6520 core 2 duo all intel laptop with HDA Intel audio.

Pups currently in kennel :D Older LxPupSc and X-slacko-4.4 for my users; LxPupSc, LxPupSc64 and upupEF for me. All good pups indeed, and all running savefiles for look'n'feel only. Browsers, etc. solely from SFS.
works on my laptop running slacko 5.7 thank you!

preamp in slacko 6.3.0
I can't get the add a preamp in slacko 6.3.0 using the /etc/asound.conf file with this code to work (this works with slacko 5.7). Has anyone gotten a preamp to work in 6.3.0?
