Volume Problems / Alsa Mixer

The Issues

This wiki helps solve problems like: "Sound will come out of the speakers, but will not come out of the headphone jack." or "Sound works ok, but the microphone channel won't work"

The Steps:

• open alsamixer in terminal
• check the volume level of the channel that isnt working for the user
• use the keyboard arrows to raise volume on that channel to ~90%

Procedure

1) Open terminal and alsamixer

At the top taskbar, open

applications> accessories> terminal

and that will open the terminal program

At the input prompt, type

alsamixer

and press 'enter'. This will open the alsa mixer program.

2) Check to see if alsamixer mixer levels are the problem

Find the mixer channel that corresponds to the user's problem, and look at the volume level for that channel. If it is at 0, then this is probably the user's problem.

If not, the user's problem may be somewhere else

3) Change the volume for the channel

Use the keyboard arrows left and right, and use the right arrow to select the volume settings for the appropriate channel (this is the mic channel). Then use the up arrow to raise the volume of this channel to between %80-100. Now press escape to return to the terminal prompt, and then close the terminal window.
