When I've had issues with sound not working, it's usually been because something is using the sound card and preventing whatever application I'm using from accessing it.

If you do:

Code:

lsof | grep snd

That should tell you what's using the sound card. You may have to grep for something else, if your system doesn't use /dev/snd (not sure if that's standard or not).

Also, you may already be aware of this, but just in case... using root to run your X session is a very bad idea. You should create a user account for yourself, and use su when you need root permissions.

mattca this is the output of lsof | grep snd

Code:

#lsof | grep snd
kded4     5270     lavloz   23u      CHR      116,8      0t0     1580 /dev/snd/controlC0
kded4     5270     lavloz   24u      CHR     116,17      0t0     6791 /dev/snd/controlC1
kded4     5270     lavloz   25u      CHR     116,20      0t0   311767 /dev/snd/controlC2
kmix      5497     lavloz   11u      CHR      116,8      0t0     1580 /dev/snd/controlC0
kmix      5497     lavloz   16u      CHR     116,17      0t0     6791 /dev/snd/controlC1
kmix      5497     lavloz   17u      CHR     116,20      0t0   311767 /dev/snd/controlC2

I created a user but it doesn't work too
I noticed a thing :
I use XMMS to listen file but it doesn't use snd, it use dsp.
this a peice of my lsof | grep xmms when i listen to something (sure i don't listen anything on speakers) :

Code:

lsof | grep xmms
xmms      5957     lavloz  mem       REG        8,1   153614  1213917 /lib/ld-2.15.so
xmms      5957     lavloz    0r     FIFO        0,8      0t0   562175 pipe
xmms      5957     lavloz    1u      CHR        4,2      0t0     1058 /dev/tty2
xmms      5957     lavloz    2u      CHR        4,2      0t0     1058 /dev/tty2
xmms      5957     lavloz    3u     unix 0xe73c5680      0t0   644847 socket
xmms      5957     lavloz    4u     unix 0xe73c4780      0t0   644850 /tmp/xmms_lavloz.0
xmms      5957     lavloz    5r     FIFO        0,8      0t0   645602 pipe
xmms      5957     lavloz    6w     FIFO        0,8      0t0   645602 pipe
xmms      5957     lavloz    7u     unix 0xdcbdac80      0t0   645603 socket
xmms      5957     lavloz    8r      REG        8,3  1428169     4194 /d/La VloZ/quran/061.mp3
xmms      5957     lavloz    9w      CHR       14,3      0t0     8765 /dev/dsp

As u see the two last lines

Code:

xmms      5957     lavloz    8r      REG        8,3  1428169     4194 /d/La VloZ/quran/061.mp3

Is the path of my file

Code:

xmms      5957     lavloz    9w      CHR       14,3      0t0     8765 /dev/dsp

Is /dev/dsp

Does the problem is here?? if yes how do i make XMMS use /dev/snd (snd here is a directory)??

Okey Thank you, i solved it

Note: This solution for ALSA.
First you have to know the ID of the device which you want use

You can get the devices IDs list from /proc/asound/cards
Or from

Code:

aplay -l | grep card

Then you have to create a file in your home directory named ~/.asoundrc
And write on it these 3 lines which make your default device

Code:

defaults.ctl.card DEVICE_ID
defaults.pcm.card DEVICE_ID
defaults.timer.card DEVICE_ID

Change DEVICE_ID with the number you've got from /proc/asound/cards or from

Code:

aplay -l | grep card

And test with this command :

Code:

speaker-test -c 2 -t wav

I hope everything is clear

Note: if you reboot your computer and you don't have the sound again, check the /proc/asound/cards for device ID maybe its has been changed without your knowledge (Like in my case)
