First thing to do is make sure that your sound is not simply muted. Look for that first; I think running the alsaconf command will allow you to check your sound too on RHEL5.

If you realize that it's not muted, could you post the content of /etc/modprobe.conf
The output for cat /proc/asound/card0/codec#* | grep Codec would also help.

Thank you for your precious help.


I am sure that sound is simply unmuted and the command 'alsaconf',when i enter, it shows "bash: alsaconf: command not found".
Here is the content of /etc/modprobe.conf:-

[root@localhost ~]# alsaconf
bash: alsaconf: command not found
[root@localhost ~]# cat /etc/modprobe.conf
alias scsi_hostadapter ata_piix
alias eth1 sk98lin
options snd cards_limit=8
alias snd-card-0 snd-hda-intel
options snd-hda-intel index=0
[root@localhost ~]#

[root@localhost ~]# cat /proc/asound/card0/codec#* | grep Codec
Codec: Generic 14f1 ID 2c06
Codec: Generic 1095 ID 1392
Codec: SigmaTel STAC9228
[root@localhost ~]#

Pls help me.
Thanks.

Ok, thank you for your info. It is probable that your problem is that although RHEL5 does recognize your sound card, it doesn't recognize it properly. So what you will have to do here is edit modprobe.conf, in order to specify a model for your card.

First thing that you must do is make a backup copy of your modprobe.conf file. It's always good to take our precautions.

Then open modprobe.conf with gedit (or whatever editor that you like) and you will add what I wrote in red below:

Code:
alias scsi_hostadapter ata_piix
alias eth1 sk98lin
options snd cards_limit=8
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0 model=dell
then save it, restart your laptop and test your sound. If it still doesn't work, edit modprobe.conf with another model name. Here are some suggestions:
ref
3stack
5stack
laptop
dell-3stack
dell-d21
dell-d22
dell-d23
dell-m21
(or -m22, -m23, -m24, -m25, -m26, -m27)
fujitsu

Try that first. If after all these you still have no sound, let me know and I will suggest you more model names that you can try.

Ok, well there are some more model names that you can try. Go to that link below and scroll down to the line 739 which treats the module snd-hda-intel. You will find a series of model names associated to different codecs.

http://www.mjmwired.net/kernel/Docum...figuration.txt

Try them all. Chances are one of them will do. Start with those associated with the STAC**** codecs since they are the ones closer to yours. If none of them work, try the other names, even those like thinkpad, toshiba and acer. And in case it still doesn't work, remove that line
Code:
options snd-card-0 index=0
I made you add previously and try all the model names again.

Ok, I just want to make sure that I understand here. You are saying that now you get sound but these messages appear?

If that is the case, I think you can solve that by running a command like gst-register (as simple user or as root, I'm not sure here). You can check in /usr/bin/ to see what the right command is.

Thank you verry much for ur kind response.In /usr/bin/ dir,there is no match like gst-register.I am attaching here screenshot of output of alsamicxer command.

ATI SB450, SB600, RS600,

It doesn't seem to me like your sound is working, not even with these module names. It looks like editing modprobe.conf didn't do the trick. I thought it would, sorry.

However, there is still a possible solution and it is for you to first, restore modprobe.conf to its original state, and to update ALSA to a more recent version. Unfortunately, that is something that I never really attempted myself so I wouldn't be able to tell you how to proceed; sorry again.

Hopefully, somebody else can give you more information.

No, don't.

You must know what you are doing before attempting something like that. Please go to this link below that gives some useful explanation and links for packages. It's for Fedora and RHEL-4 but it must be good for RHEL-5 too. If you want to check the proposed ALSA packages, just make sure that you replace "el4" in the addresses with "el5". There's also a link to the alsa-project web page and their bug tracker which would be a good idea to visit as well; chances are there are cases similar to yours. If you need to ask more questions there is at the end of the page an e-mail address that you can write to, or don't hesitate to come and ask them here.

Good luck.
