Problem with sound

Gins · 02-03-2012, 01:54 PM

Hello

I have installed Mandriva 2010 on a desktop computer. The sound is not there. I just hear a hum. I played some music from YouTube. No sound comes from the speaker; only a hum.
I just see a man is singing on the screen. Sound doesn't come

Where do I find the sound drivers? I don't know the folder where you could look for the sound drivers. I firmly believe the problem is that there are no sound drivers installed.

Please tell me the way to check the sound drivers.
.................................................................................................... .......................................
However I have found the following when I try to configure it.
Here you can select an alternative driver (either OSS or ALSA) for your sound card (VIA Technologies, Inc.|VT1708/A [Azalia HDAC] (VIA High Definition Audio Controller)).

Your card currently use the ALSA "snd_hda_intel" driver (default driver for your card is "snd_hda_intel")

For starters, have you run alsamixer and made sure nothing is muted and the sound levels are turned all the way up?
The humming may be due to a microphone input. Try muting the mic in alsamixer and see if the hum goes away. I had to do this on my computer.

If alsamixer does not help, post the output of your sound hardware that Mandriva sees from the terminal:

Code:

lspci | grep -i audio

And post the output of the audio drivers that are loaded:

Code:

lsmod | grep -i snd*

This should help to diagnose the problem

Yes, the command 'alsamixer' works fine.
There is nothing I could do with it. Probably I don't know much about meddling with it.

Kind regards

Gins · 02-04-2012, 04:07 PM

Thanks repo for the reply.

The 'M' is not under the bars. It is 'O' under the bars.

Still no sound comes from the speakers. Just the hum comes from the speakers.

(I really hope that my comments are excellent!! Time will tell how excellent they prove to be!!! ...)

It seems that your computer uses the VIA Technologies, Inc. VT1708/A [Azalia HDAC] audio chip; and Mandriva is using the snd_hda_intel audio codecs for it.
A quick search found this bug on the Mageia site. Mageia is based on Mandriva. It is therefore possible that this bug may exist in Mandriva as well:

I have found that the problem is the way the newer Linux kernels use ACPI to
enumerate all the PCI host bridges, and part of the host bridge description is
the “_CRS” (current resource settings) property, which lists the address space
used by the bridge.

I found this information here:
http://article.gmane.org/gmane.linux.kernel/947909

I have added 'pci=use_csr' as a kernel boot parameter on my system and this has
resolved the issue. I now have sound. ...
This is a typo: (I have added 'pci=use_csr' as a kernel boot parameter)
It should be 'pci=use_crs'

So try adding pci=use_crs to your kernel boot parameter(s) in grub and see if this gets you sound.
You can add pci=use_crs to your grub boot parameter on the fly as the computer is booting by hitting the "e" key over the kernel line (the vmlinuz line in grub legacy) as the computer boots and add pci=use_crs to the end of the vmlinuz line (i.e., the kernel line). Then hit Esc to exit, and "b" to boot. This will not make any permanent changes to your system. This will function as a test howver to see if adding pci=use_crs to your boot parameters gets you sound.

It is my understanding that Mandriva 2010 still uses grub legacy. It has been a while since I have worked with grub legacy. For further info see:
https://wiki.archlinux.org/index.php..._the_boot_menu

Mandriva 2010 is a bit old these days.
You may want to consider trying a more recent distro and see if you get sound.
Try running a Ubuntu 11.10 live CD and see if you get sound.
If you are using an older computer that has older hardware and limited resources, then try using a Lubuntu 11.10 live CD. Lubuntu is very fast and light and works well on older computers. It uses the same 3.0 kernel as Ubuntu 11.10. The newer kernel in Ubuntu may give you sound. Ubuntu 11.10 also uses grub2, which works differently than grub legacy.
Write back if you need more help.

I have tried in vain to solve the problem today.
I badly need your support.

By the way, I had a similar problem with the screen resolution. The browser didn't cover the entire screen. I have played with the command 'xrandr' for about 2 hours. Now it works better than before. It is not 100% correct. I accept the current setup.

I was still editing my last post when you posted this.
Please read my last post above this and see if any of that helps.

Thanks tommcd for taking time to reply me again. I was waiting for your input all this time.

The following is my 'menu.lst' file

Where do I ring the changes on the 'menu.lst' file?

When in 'alsamixer' increase the level for each of the device object levels, move between each with 'arrow-keys'. Then press 'Esc' & do 'alsactl store'. After which you should see the control levels changed in whatever 'X' mixer you choose.

Hi
I did the following as you suggested:
press 'Esc' & do 'alsactl store

I rebooted the computer and tried in vain to play a song from the YouTube. I see a singing man. However, no sound.

onebuck · 02-05-2012, 05:00 PM

Hi,

Which distro & DE/WM?
What do you see when a mixer is opened for DE?

You can adjust the mixer setting on the desktop?
What about going to system settings and try testing the snd-intel device?
