Troubleshooting in Build: Audio

DESKTOP BUILD: AUDIO TROUBLESHOOTING

You're going along your build checklist just fine. You thought it was odd that no Ubuntu drums were audible when you booted up, but you would be reaching the sound test portion of the build later on, so you didn't worry. Only, now IS later on, and you have no sound. Here's what to do:

As always, recheck your connections	Be certain that the speaker wire is connected to the correct, "outgoing" speaker port in the system and that the speakers are plugged in to a power outlet and "on" at a reasonable sound level set. Try plugging in the speaker cable into the front panel's headphone icon and see if any sound comes from the speakers then.
There is no sound on the "Sound Check" step of the "Basic Check" Checklist	First thing you want to do is click on the small speaker icon located at the top right portion of your monitor and make certain nothing is muted, and the "Output Volume" is set to a moderate level. If this still doesn't work, open a terminal and type in "alsamixer". You should see a screen with an interface of many different volume control levels. Go to both "Master" and "PCM" by using your arrow keys and set each to around 90.
Replace that sound card!	If all else has failed, shut down the system, disconnect the power chord, and put in a sound card if the current sound card is onboard, or replace the sound card if there was one in the system already. Turn on the computer again and begin doing all the same procedures as before.
I have sound, but my CD-ROM/DVD Player isn't working	If you find the CD/DVD player isn't working, look into the system and make sure that the IDE/SATA connection is good. If there are other ports then try plugging the connections into other IDE/SATA ports and see if you have any luck. If not,
