12.04 Speaker Static

Question

Since upgrading to 12.04, I've been having issues with my speakers:

They seem to be making an odd hissing noise (sort of like static) and they sound really tinny.

Is anyone else having these problems or is it just me and is there any way to fix it?

(bear in mind that this is a new problem that I've never had until I upgraded yesterday)

Answer 1

Turning down the mic boost using alsamixer fixed it for me.

To do that, open a terminal (Alt-Control-T will do this) and enter the alsamixer command. Pressing the Tab button brings up "Capture" screen. Use the left and right arrow keys to select the mic boost slider and reduce it with the down arrow key. Press the Esc key to quit alsamixer.

Answer 2

I've only been able to diminish the audio static by doing two things. First, lower the PCM volume level to 80ish. Type "alsamixer" into the terminal and arrow over to PCM then arrow down. Also,this. Hope this helps.
