Using 13.04 64-bit, my sound is having some issues. Whenever I adjust the volume higher/lower my speakers/headphones make a sort of crackling noise. It's not very noticeable when I'm playing music or watching a video, but when I adjust the volume with no sounds playing I can clearly hear a distinct crackle sound. It also appears to pop randomly as well every couple of minutes, but I can only duplicate the issue when I raise or lower my volume.

Here is the output from lspci -v | grep -A7 -i "audio"

And also the output from sudo aplay -l

These outputs were posted to show the sound card in my laptop. I have tried some troubleshooting techniques here: Ubuntu Wiki however they did not resolve the issue. Any help with this issue would be greatly appreciated. Thanks for any help in advance!

It sounds to me like a dry or loose solder or connection to your computers speakers or may be dirt under the sound up/down keys. –  SimplySimon Aug 11 '13 at 7:55
    
No matter how I adjust my volume, it always crackles. If I adjust it with my mouse wheel, or use the function keys or or adjust the sound applet itself, it always crackles. I just can't determine if it is a software or hardware issue. –  dswhite85 Aug 11 '13 at 9:08
    
as i said, I believe that it is more likely to be a hardware problem. –  SimplySimon Aug 11 '13 at 9:11
