Sound Configurations

[Diego Nascimento]

Hi all,

i migrated to fedora distribution a short time ago and when i tried to set
the volume of the different outputs, i couldn't. Today i just can configure
the master volume.

How can i configure alsa to control the volume of all different outputs
separated?

Hi Diego,

If you right click on the "Speaker" icon and select "Open Volume 
Control" you will be able to "Edit->Preferences".  From there it is 
possible to add and remove different input and output controls.

Unfortunately, there is no way from there to distinguish which are 
inputs and which are outputs and things don't always make sense (to me). 
  For example, there is a "CD" input but it doesn't control my CD.  My 
CD's volume is controlled by the "PCM" output.

hth,

That is because there are different ways to get sound from a CD. You
can use the audio output from the CD-ROM drive - that shows up on
the CD input. You can also grab the digital data from the CD-ROM
drive over the data cable, and convert it to analog using software
on the computer - this will show up on PCM just as playing a music
file from a hard drive will. Some CD-ROM drives also have a digital
out connection on the drive, and some sound cards have an input for
this. I don't know what that input is labeled.
