What OpenSUSE version are you using? What Desktop/Windowmanager? (ie. Gnome or KDE?). If KDE, is this v.3.5.x or 4.xx ?

now the problem is that... m getting sound as echo... i mean... like we hear a "Ding"

in my laptop it goes like Ding Ding Ding Ding DIng Ding and goes on... it never stops... [/b]

Please check your mic is switched off, although to be frank, this doesn't read to be a mic problem.

I have seen this problem with openSUSE-11.0 alpha3 on KDE-4.xx.

also i have installed the alsa drivers.. but no help... [/b]

Alsa drivers provide you sound. With no Alsa (nor OSS in some cases) you wont' have sound. So of course you have installed the alsa drivers. ... The question of interest is what version of the alsa drivers. What is the output of:
<span style="font-family:Courier New">rpm -qa | grep alsa
uname -a
cat /proc/asound/cards</span>

thanks for the quick reply...

my system info :

OS: Linux 2.6.22.5-31-default i686
System: openSUSE 10.3 (i586)
KDE: 3.5.7 "release 72"

a strange thing is happening... i installed alsa driver 1.0.16 (driver,lib,oss,utils)

but rpm -qa | grep alsa is showing 1.0.14...

i installed by commands...

./configure && make && sudo make install


Outputs of your commands..

rpm -qa | grep alsa

- alsa-utils-1.0.14-27
alsa-oss-1.0.14-23
alsa-1.0.14-31
alsa-plugins-1.0.14-41


uname -a

... waiting for reply...

Ok, thanks. .... Its clear you have not updated your kernel yet (with the latest security updates).

cat /proc/asound/cards

This shows much less detail than I expected. This makes me think an update to alsa 1.0.16 may be needed.

a strange thing is happening... i installed alsa driver 1.0.16 (driver,lib,oss,utils)

but rpm -qa | grep alsa is showing 1.0.14...

i installed by commands...

./configure && make && sudo make install [/b]

This could be your problem. You have a mix of openSUSE-10.3 rpms for 1.0.14 of alsa, mixed in with 1.0.16 custom compiled rpms. Which means you have a hodge podge of libraries .....

I recommend you go back to the directory where you typed "./configure && make && sudo make install " and type "make uninstall" and REMOVE 1.0.16 of alsa.

Then install it from rpms instead with these commands with your PC connected to the internet, from an xterm/konsole with root permissions. I recommend you copy and paste this to avoid syntax errors:

zypper ar http://download.opensuse.org/reposit...openSUSE_10.3/ multimedia

zypper install alsa alsa-driver-kmp-default alsa-utils alsa-tools alsa-firmware alsa-oss alsa-plugins libasound2

zypper rr http://download.opensuse.org/reposit...openSUSE_10.3/

rpm -qa | grep alsa
cat /etc/modprobe.d/sound</span>
and post the output URLs provided to you by running the two diagnostic scripts from the openSUSE audio troubleshooting guide:

update done but problem not solved..

here is the info.

hope i supplied it as you want..

rpm -qa | grep alsa
alsa-1.0.16.hg20080510-2.1[/b]

This looks good. I'm now checking the scripts.

As an after thought, I hope you are logged in as a regular user for these sound tests, and are only using root permissions when absolutely essential (for example for s/w installations)

I hope you did the "make uninstall" like I requested. Else nothing we try may work.

First, I would like you to do a test in run level 3, to ensure there is not a setting in your Desktop/Window manager that is causing this affect. Please reboot your PC to run level 3 (a text log in). You can do that by typing "3" (no quotes) in the grub menu when it appears. Your PC will boot to a text prompt. Log in as a regular user (and use regular user password). Then type (note this is case sensitive):

speaker-test -c2 -Ddefault -twav

Note you stop that sound application by pressing <CTRL><C>

You can reboot from this point by typing "su" (enter root password) followed by "shutdown -r now" [no quotes in both cases]

When you performed this sound test, do you still have the same echo? If there is no problem in run level 3, then the echo is a desktop setting that is causing the problem, and you need to investigate your desktop settings. If you still have the echo problem, then please go on to the next step.

Your hardware codec is a CX20549, which is the same as a Conexant 5045. The ALSA-Configuration.txt file notes the following:

Conexant 5045
******laptop-hpsense****Laptop with HP sense (old model laptop)
******laptop-micsense** Laptop with Mic sense (old model fujitsu)
******laptop-hpmicsense Laptop with HP and Mic senses
******benq********Benq R55E

That guidance relates to added content in the /etc/modprobe.d/sound file.

Please edit your /etc/modprobe.d/sound file, and change it to:

options snd-hda-intel enable=1 index=0 model=laptop-hpsense
# wRyD.ALuUqiQILF2:MCP51 High Definition Audio
alias snd-card-0 snd-hda-intel

Then in an xterm/konsole with root permissions restart your alsa with: <span style="font-family:Courier New">dmesg > dmesg.txt</span> and search for sound/alsa errors in the newly created "dmesg.txt" file. DON'T POST the entire dmesg.txt file here. It is too long.

Good Luck!

If the above efforts fail, also try booting with "acpi=off" and see if that make a difference (its possible your dmesg file will tell of ACPI problems).
