I was playing xine, xmms, mplayer with complete satisfaction in Fedora Core 2. For some unknown reasons suddenly i there is no sound from my comp. I checked the cables and also tried the following thing..
rm -f /etc/sysconfig/hwconf
rm -f /etc/modprobe.conf
service kudzu restart

then the soundcard is autodetected... but still no sound.. the mixer settings r ok...
what can be the problem?

Is there another OS on that computer on which you can test the sound?

It's always possibile try on the same machine if sounds work with a bootable like knoppix.
Than if it works looking at which module knoppix use i.e. snd_via82xxx or whatsoever then let fedore use that module instead that ones used by default.

the sound is compleatly ok on other OS.. i tried Yoper GNU/Linux..
There was no problem with Fedora also.. but it happened suddenly..

is there a was to find out if any program is blocking my soundcard.. cuz once i got such an error from xmms.. though no other sound program was running..

please suggest a way to attack this problem.

Hi anz,
let me understand.
What do you mean with first sound was working and suddenly....

Every program (xmms,xine,mplayer) was working first??

And now no one of the above programs works anymore??

Or only xmms stop working as I can understand from your last post??

If sound doesn't work with any of the progams mentioned and you haven't installed nothing new (i.e. upgraded kde,kernel or whatsoever) maybe it's your system that for unknown reasons doesn't load the correct sound module for your card.

Don't ask me why,but try the things I've suggested in the post before.

Boot with a live cd don't touch your hard disk.You should try now if it works!

If with a bootable like knoppix that has maybe the better hardware recognition tool sound won't play it's an hardware problem. (i.e. if you have a separeted sound board it could be broken, in the same way something could be broken in the integrated audio chip if you've got on board audio).

If it works with a bootable How I have said in the post before open "K menu | System | Info Center " to detect which sound module is in use by live cd copy the name of the module on a sheet than reboot the system on your hard disk and using the sound card configuration wizard choose as default the driver (module) you've written on the sheet.

If only xmms is not working (i.e. try to play an .mp3 file if the status bar in xmms goes ahead but you couldn't hear sound) first check xmms imput plug-in "right click on xmms window | Options | Preferences | Audio I/O Plugins" maybe someone is disabled or always if only xmms doesn't work try with right click on "K menu | Menu Editor | Multimedia | Xmms " and read what's written in the line "Command" if it's like this "soundwrapper xmms" erase soundwrapper (if this is the case this start command is the trouble) and leave only "xmms %U".

If you're looking for someone with a magic wand as maybe appears by your latest post be aware.

We are only people like you maybe with a little bit knowledge more than you but not wizards!

We can only suggest you some way to solve your problem but you have to find which is the right way to solve it!

We are trying to help you but you should help yourself no one, I think, have the right solution for you simply because we can't sit at your pc.

You have said that xmms gives you an error but you don't post it!

How can we help you??
I've tried with this post but as I said you should find by yourself the solution following our suggestions.

There's no other way!!

Can you post the output of lsmod and lspci?

try sndconfig on the command prompt to configure socund card.

try installing newer version of xmms.

try playing mpg321 <mp3 file> on command prompt itself.

Good luck,

walker, thanx a lot... i think i was a little confusing.. and trust me.. i really try to do whatever possible to solve problems... not only mine but i help others also if possible.. but this time i am perplexed... everytime the C-Media CM8738 driver is used for my soundcard.. so i dont think really rthat there is a better driver.. but i will follow what u have said.. and i am short of words in thanking you.. because u r the ones who really spend ur valuable time so that others can live happily... thanx again.

everything were working properly.. and nothing is working now. there is no sound from my PC.. not a mp problem or something like that.. i will try the knoppix thing.. but i have to get a copy of that.. meanwhile i tried Yoper Linux instead of knoppix. yoper produced sound with no problem. So the soundcard is okay..

i forgot the error from xmms... but its not that only xmms is not working...
it said some program may be blocking my soundcard.. but i remember that.. at that time i was not running any other application that could produce sound. So i thought that if i can find out if any program is blocking my soundcard.. and that program is getting loaded always.. then i could solve the problem.. but i dont know how to find if a program is blocking my soundcard.
the

but i can see that the kernel modules are there..
may be i will have to reinstall the whole system (oh no!)..
may be i did something which caused this .. but i am not sure what i did..

You didn't happen to install/run any KDE/GNOME based programs did you? Could you post the output of ps -A (verifying beforehand that the sound still doesn't work)?

Also, what audio output plugins/drivers are you using in XMMS, Mplayer etc? By this I'm asking are you using OSS output, ALSA, or some sort of sound server.

And yes sound still does not work... i did install some GNOME/KDE based applications.. they were running smoothely too.. like Kafeeine, Gxine.

gstreamer-properties say im using ALSA, also OSS is available.. when i click on the test sound button.. no sound is generated.. though when the situations were normal.. i could hear a long beep.

This may sound stupid but I missed this 3 times before I found it.

I had a similar issue earlier today when I updated gstreamer. Something caused the option Analog / Digital Output Jack to be checked on mute in Volume Control. i unmuted this and everything was back to normal. This was at the end of a very long list of options in Volume Control.

I hope this is of help. Though it is probably not.

mixer settings are ok..
none is muted!
And i tried this in single user mode
#mplayer file.mp3
could not hear any sound..
does this have anything to do??

Could you post the output of mplayer when you do this?

hey.. i fixed the sound problem.. amazing isnt it? lolz!
well my modprobe.conf reads like this now .. and it solved the problem

alias eth0 8139too
alias usb-controller uhci-hcd
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF verion 1.0.6 ---
alias snd-card-0 snd-cmipci
alias sound-slot-0 snd-cmipci
# --- END: Generated by ALSACONF, do not edit. ---

the sound-slot-0 line was missing previously.. thanx for all ur supprt!
cheers!

PS: so is it that kudzu did not detect the 'sount-slot 0' thing...
is it a bug of some kind?? i copied the line from yoper distributoin of GNU/Linux
