<title>I hear crackling or buzzing when sounds are playing</title>
22
<p>If you hear crackling or buzzing when sounds are playing on your computer,
23
you may have a problem with the audio cables or connectors, or a problem with
24
the drivers for the sound card.</p>
28
<p>Check that the speakers are plugged in correctly.</p>
29
<p>If the speakers aren't fully plugged in, or if they are plugged into the
30
wrong socket, you might hear a buzzing sound.</p>
34
<p>Make sure the speaker/headphone cable isn't damaged.</p>
35
<p>Audio cables and connectors can gradually wear with use. Try plugging the
36
cable or headphones into another audio device (like an MP3 player or a CD
37
player) to check if there is still a crackling sound. If there is, you may need
38
to replace the cable or headphones.</p>

<p>Check if the sound drivers aren't very good.</p>
43
<p>Some sound cards don't work very well on Linux because they don't have very
44
good drivers. This problem is more difficult to identify. Try searching for
45
the make and model of your sound card on the internet, plus the search term
46
"Ubuntu", to see if other people are having the same problem.</p>

<p>You can run <cmd>sudo lspci -v</cmd> in the <app>Terminal</app> to get more information about your

54
<p>Are we shipping any sort of device manager? If we do (or even if we
55
recommend one, but people need to install it), and if you can get all
56
the information you need about the sound card from that, we should
57
link to that for getting info on your sound card.</p>
