Fedora 7...audio problem - laptop

[shortchar]

I also had a Toshiba Satellite laptop on which the sound did not work. However, adding the line with "model=3stack" to modprobe.conf ended up working for me, after a reboot. I'm still having sound issues though... my laptop doesn't recognize headphones -- the sound comes through both the speakers and headphones when they are plugged in.

I am using xmms in Fedora 7 (kernel 2.6.23.1-21), and I had the same problem. Please see attachs for details
I tried all above solutions but not successful. Now, I hear no sound and can't play multimedia programs.

Besides, I tried some solutions as:

chmod -R a+rwx /dev/snd

or

yum -y install xmms-arts

after choosed arts was output plugins in xmms, and ALSA for Audio device in kcontrol but all that don't make effects.

I am using GNOME, when run any command in Terminal, I always get messages like:

$ sudo gedit /etc/modprobe.conf
/bin/sh: /usr/bin/esd: No such file or directory
/bin/sh: /usr/bin/esd: No such file or directory
/bin/sh: /usr/bin/esd: No such file or directory
/bin/sh: /usr/bin/esd: No such file or directory
/bin/sh: /usr/bin/esd: No such file or directory
/bin/sh: /usr/bin/esd: No such file or directory
/bin/sh: /usr/bin/esd: No such file or directory
/bin/sh: /usr/bin/esd: No such file or directory

after that gedit run. I feel very furious about this error.
How to reinstall esd or fix?

I tried compile kernel again to support ALSA but not successful. Can anyone help me? Thank in advance.
