How I chage alsamixer in the command line so that I can fine tune alsamixer and get rid of some white noise? Right now it looks like this.

  • @blvdeer, I tried your suggestion but I got this error message-"This sound device does not have any capture controls. It sounds like I may need to find a different way to eliminate the white noise. So thanks anyway, you too, rajenupula. Sep 15, 2013 at 5:19

Here some of the commands can help you.

  • Use the right and left arrow keys to navigate through the sliders.
  • At the bottom of each slider you see either 00 or MM. Toggle these with the M key. MM means muted, 00 is enabled.
  • Use the up and down arrow keys or the Page Up/Page Down keys to control the sliders. Page Up/Page Down move the sliders in increments of five, and the End key resets to zero. When there are two channels controlled by one slider, Q increases the left channel and Z decreases. E increases the right channel, and C decreases.
  • Press F2 to see all the system information on your sound cards. If you have more than one sound card press F6 to display a sound card chooser.

It depends on what your current soundcard supports, as its HDMI its showing S/PDIF. Try pressing F5 to display all options that the soundcard supports.

You can also change sound device/card with the F6 key
