audio
 

i have recently installed the AMD64 version of ubuntu, and i have no sound. i tried using ubuntuguide.org, but there is only sound set up for i386 machines. if anybody could help me i would appreciate it,

okay, do you have mixer to start with so that you can control the output? I use aumix and it works fine. alsamixer also works fine.

make sure that your master/volume and your pcm aren't set to zero.

if that doesn't work, check you sound devices. I don't really know where they are in ubuntu but try
/dev/mixer /dev/sequencer /dev/sound/ /dev/snd/
check that you have permissions by doing:
#ls /dev/mixer -l
and with all the others. to make really sure you have permissions you can do
#chmod 777 /dev/mixer
and with directories like /dev/snd and /dev/sound you do
#chmod 777 -R /dev/snd

how did that work out for you?
if that didn't work, can you find your soundcard and do you have a driver for it? type
#cat /proc/pci | less
and check.

good luck!
what worked and what didn't?

open a terminal and type alsamixer

you will see several slider bars and some small boxes with mm in them.

the boxes are switches. Use your arrow key to move over to the right, and don't be fooled they go over quite a ways, not just what you see in your screen.
almost all the way over you will see a switch for analog/digital.
to toggle the switch type m. When it is on it will turn green.
You may have 2 mixers available to you both may need to be turned on.
one is alsa and one is oss. You can do both from this console.

to switch mixers after you have turned them on you can go to sound and video on menu then select volume control. now select the file menu and you will see a change device to select your mixer.

the alsamixer is a lil cryptic so I like to start a cd playing to make sure I hit the right switch, if its the right one you will hear sound.

want to thank you both for the help :) i'm a noob, haha, but we all have to start somewhere right?

do have another question, i am also running cedega, but the alsa sound is failing the test. i have turned on all alsa that i know of, and still isn't passing. any ideas would be great! thanks

make sure it is alsa that you use. open xmms and see if you use alsa (which you should use) or if you use oss.
if you choose alsa and it doesn't work, then you haven't installed or configured alsa properly.

otherwise, don't know...
