Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Whenever I capture sound from my sound card (in Audacity), the volume is low. I've looked around in alsamixer but I don't know which control the capture uses. Which one controls the input level?
My sound card is a Creative Labs SB0090 Audigy Player
I have Alsa Mixer 1.0.13 and my kernel is 2.6.13-15.15-smp
I've also used KMix but like I said, I don't know if line, line1 or line2 is being used.
Wow! I thought I was the only one who had this problem when I got Audacity for Linux. When I was recording, it didn't matter whether the input volume on Audacity was at the top or right at the bottom, it always had the same input. What I did then (just a couple of weeks ago) was select the entire recording and use the amplify tool under the "Effects" menu. But now, I followed your advice, Comprookie, and looked in my Volume Control menu. I went to Edit -> Preferences and clicked the box for "Line-In Capture". Hopefully, the next time I'm recording, it will work. I would try this, gymnart. If that doesn't work, you can always use "Amplify". Good luck!

I will look at the Line-in Capture in Audacity.
When I try the Amplify tool, the quality gets distorted sounding, like it is in a tin can. Also, "Clipping" happens. I'm wondering if there are certain special settings so that won't happen if I use the Amplify tool.
I solved the problem on my system! The problem was the "Capture" level on the volume control. I'm using Ubuntu, but hopefully this will be mostly the same on what you're using:
Right-click on the speaker/volume control on your taskbar
From the menu that pops up, click on "Preferences"
What opens up on my system is a window called "Volume Control Preferences". This lets you pick which part of the audio setup you want to adjust the level for. Scroll down until you see "Capture", click on it it once and then click OK.
Now go back up to the speaker control icon on your taskbar and left-click on it. You should now be adjusting the input level for sound capturing. Drag it up until it is at a good volume (it's best to do this while recording something in Audacity so that you can see how loud the recording is).
After you're done, you can go back to the original volume control by following the same steps, but this time clicking on "Master" under Volume Control Preferences.
That's how I did it; I assume this should work for every kind of recording, your setup may be a bit different. Also, once you're done, the MIC input level on Audacity is irrelevant; you adjust the Capture level to change the volume. Good luck!

ok, i have now tried that and I just have KAMix and QAMix (both are the same thing) and neither has anything in the capture feature. Under that tab, it just has a Mic Boost box which I can check and uncheck but there are no volume levels.
I also looked into Audacity's controls and toolbars but I noticed that I do not have a Device Control toolbar either.
I'm glad that you solved your problem on your system, "The Other Guy".
