No sound, or is there?

[Gori]

When I installed FC2, I heard a guitar playing, to tell me that my audio card was found, but now I can't get any sound out of it at all.

The only time I actually hear something is an audible pop when I press some buttons in the KDE Volume Control thing.

Also: I have nothing but a clean FC2 here, I'm not completely sure what SHOULD make a sound, but I think the games included, with volume settings, should make some sort of sound anyway.

Please help. :)

Did you try to edit the mixer settings?

[Gori]

Oh yes.

And the Sound Card Detection thing no longer detects my AC97 based Intel Audio. It did during setup, but not anymore.

This is a MythTV box, and it really isn't any fun to watch TV or movies without sound. Any help is really appreciated, before my girlfriend says that Windows XP sure was better, and I have to go back to having it a Windows box again. :)

Here's some more info, maybe this will make it easier to help me out:

When I first installed FC2 it did detect and play audio fine.

Soundcard Detection now says:
Vendor: Intel Corp
Model: 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller
Module: snd-intel8x0

But when I click "Play test sound" there's quite a long wait, and there's no sound at all.

Atleast there is a wait. The problem would be if the dialog asking did you hear the sound would automatically appear. what does 'modprobe snd-intel8x0' tell you? Nothing? Or are there errors? What about 'lsmod'? Is it loaded? How does your /etc/modprobe.conf look?

[Gori]

There's a wait, and there's other reasons for me to think that this might actually be trivial. When I'm in the mixer (same thing with both gnome-alsamixer and kmix) I get a really audible pop when clicking the "Mic as Center/LFE" checkbox. And when I drag my Mic slider up there's a really annoying BUZZ. So there's definitely a connection to the sound card somewhere.

modprobe snd-intel8x0 gives me nothing at all. The modprobe.conf audio part looks like this:

alias snd-card-0 snd-intel8x0
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0

What's up Gori, im with you in having this same problem, I got my card detected on setup but now sound card is NOT detected with the sound card utility and I have never had anything but those pops when I it's loading and when I move/touch/slide some things. I have a Toshiba Laptop doing this.

Try going to control center in kde, there to sound and multimedia, there to sound system, make sure that it is anabled, and at the hardware tab select all of those audio devices and go to test sound, hopefully one should work.

[Gori]

The sound system is enabled, none of the audio devices work.

I need ALSA to work for MythTV to work properly, I think.

Any other ideas?

Have you tried using the "outdated" OSS module for the the intel sound chip. I find it works fantastically better than than the alsa one. I have the same sound chip on my Sony Laptop and I've got both drivers functioning although the ALSA driver doesn't seen to run with a high priority so when I play DVDs and such the video gets ahead of the Audio. This DOES NOT happen with the OSS driver. Also the anoying pops disappear too. However recompiling the kernel may be required

This is excerpted from a post I made back in July re Intel AC97 sound problems. Your modprobe.conf file looks fine, so try these next steps:

Open modprobe.conf.dist in your favorite text editor (as superuser, of course). The file contains a bunch of default modprobe settings, but scroll down until you find this line:

install sound-slot-* /sbin/modprobe snd-card-${MODPROBE_MODULE##sound[_-]slot[_-]}

This particular command seems to produce very erratic results for some reason. It's OK to comment it out with a # symbol and to add this line instead:

alias sound-slot-* snd-card-0

Save and close the file, and then open whatever sound mixer you're using (alsamixer, KMix, or the Gnome mixer) and set the Master, PCM, Headphone, and CD volumes to about 75% of full--you can always adjust these to your liking later. These seem to be the four crucial settings; you might also set the Line volume to at least 75%. Make sure as well that none of these are muted (in alsamixer the muting is toggled with the m key; it's pretty self-explanatory in the GUI mixers).

Try running the Soundcard Detection utility (system-config-soundcard) at this point and see what happens. Be patient; occasionally there will be a fairly long delay before the guitars play. Then pop in a CD, try to play an MP3, or whatever.

I had exactly the same problem... turned out to be my logitech webcam.. unplugged it & it worked

dunno if that helps

Got my sound card working and wanted to share my successful method.

Procedure:
physically installed C-Media PCI sound card (cheap PCI sound card) (your computer must be off for this stage!)
do Menu->System Settings->Soundcard Detection
If this program correctly identifies your sound card then your in luck.
Remember the module name it describes (mine was "snd-cmipci")
Choose to play a test sound, then when it asks "Did you hear a sound" select 'Yes'
at the command line do:
$ /sbin/modprobe snd-cmipci
(or whatever module name according to the previous Sound Detection program) This steps informs the kernel it needs to run an additional module/driver.
Restart the computer
Kudzu should come up early in the boot process and ask if you would like to configure your new hardware. Select 'Configure'.
Log in to the graphical desktop ( 'startx' from the command line)
Make sure to unmute and turn up the sound using Menu->Sound & Video->Volume Control
Make your test speakers or headphones are plugged in the correct audio jack/port.
Test the sound with Menu->Sound & Video->Audio Player

Hope this works well for you, too.
Good luck.
