Hi people!

I have Slackware 13.1 on my desktop and my Laptop.

In both cases, my sound some times works, and some times doesn't works...

When audio does not works, I reboot some times (and make a alsaconf, alsactl store)...

Do you know what it can be??

Thanks!

OBS:
My audio drive(from lspci):
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

OBS2:
When I start the KDE and the sound Driver isn't working, is showed a window saying the Sound Card was removed.

Did you try running alsaconf as root to configure alsa for your sound card?
Then run alsamixer as a regular user to set your sound levels.
Then run alsactl store as root to save these settings.
Then reboot.

Do you have more than one audio-device i.e. does your laptop have HDMI?

As you know, with the command the modules are shown which are in use a device. I'd recommend to check this in the following way: When you don't have sound, don't run alsaconf but "lspci -k" and look if the module for the soundcard is loaded. If it's not, load it with modprobe and find out if the sound is working now. alsaconf loads the modules for the sound-device, so if that's the problem you'll don't have to use alsaconf.

You may as a first step (when the sound is working) check which module is used. Then (the next time it doesn't work) check for the module. It may be, that the module isn't loaded automatically. The you can load it "manually" with modprobe.

If this is the problem, you can load the module at boot-time with modprobe in the /etc/modprobe.d directory. Be sure that the module isn't blacklisted.

Hi tommcd!

Yes, I did all this steps, and sometimes the KDE show a message that my Sound Card was removed...

Hi markush!

Now, my sound is OK, but when I do the command lspci -k only shows my audio card:

root@bahamut:/home/marcos-paulo# lspci -k | grep -i audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
root@bahamut:/home/marcos-paulo#

Its strange??

For me yes =P

Thanks!!

here as an example the output on my system:as you see there is the kernelmodule shown.

Markus

Thanks markush!

There is my output of my desktop

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
Subsystem: Intel Corporation Device d608
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel

The sound is work on the 33.4 kernel.

I will try to compile the 38.4 with the /proc/config.gz of the 33.4 to see if my sound works =D

So, if the kernel 33.4 works sound(at this time...), so using this kernel configuration I can did it works on 38.4 too?? Or just copy the .config of the /usr/src/linux...33.4 to 38.4 and make a oldconfig ?

Thanks!

Yes, this will work, and it is what I do in such cases.

What I meant in my first post was: if the sound does not work, you may check the modules and if they are not loaded, load them and check if the sound then works. In fact it is only one module to load.
I did not understand if you've checked this.

Markus

So, this never happen =D

I think its allright now!

Thanks for you markush, and all who helps!

People, it happen again... now on my laptop.....

By the way, I'm using the kernel 38.4(I happens on some kernels and on 33.4 too...)

It happens after I tryed to use my compiled kernel 39-rc5, and When i tried to start the KDM, my scrren become black, and I needed to press the shutdown button....

Do you think that the shutdown method can crash my audio driver(or his mapping on system)?

And, this is the output:

And, my KDE says there my audio device was removed....

Its strange, because it happens in a random period....

Thanks!

The KDE message may result from a missing HDMI-driver in your graphics-driver. I have a Radeon HD 5470 graphics-adapter and when I use the kerneldriver (radeon) instead of ATI's fglrx driver I have always this message of KDE. As you know HDMI is a Video/Audio-port.

Markus

Hum...
Yesterday I made a test, and when I run a music player on root user, it works....

Can it be a permission to "see or execute" anything that uses the audio?

Thanks!

you may find out to which groups you (the user) belong with the "id" command. You need to be at least member of the group audio.

Markus

Markus, I think you're right again =D

I was not a member of group audio, and When I put the audio group to my user and reboot, it works(ok ok, sometimes it can happens again...)

The most strange thing is that sometimes the audio works, and sometimes not...

But, I think that we can learn a lot with this type of problem!

Thanks again for our time!
