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)At the top taskbar, open

applications> accessories> terminal

and that will open the terminal program

2)At the input prompt, type

alsamixer

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

3)These are the volume settings for the computer's onboard mixer. Use the keyboard arrows left and right, and use the right arrow to select the volume settings for the 'Line' 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.
