Hi. I'm a newbie on Mandriva (previously used Ubuntu). Yesterday I installed Mandriva One 2008.1 for the first time, and I'm really impressed with the system. The problem is that, although the system detected correctly my sound card (SB450 HDA Audio) and everything seems well, I get no sound from any application. I checked the volumes, disabled-enabled Pulse Audio, ran alsaconf, added the instruction "options snd-hda-intel model=auto" to /etc/modprobe.conf...still no sound.

What am I missing?

Did you run #alsactl store and did you rebooted with pulseaudio disabled?Also try to right click the volume control and select Master Channel and select Master as the master volume. Then right-click again and select Show Mixer window and adjust the volume,it might help.

I did all that you told me, but still no sound. I noticed that when I right-clicked the volume control the options were only PCM, CD. Mic, Capture. I choose PCM; there was no Master option. But when I ran alsamixer on the command line, there was a Master channel, but it would not let me change its value from 0 with the arrow keys.

Thanks for the help though.

Anything I'm missing?

Are you running Gnome or KDE?Did you run alsamixer as root?Did you run alsaconf as root and after you finished with alsaconf did you then run alsactl store as root and all this with pulseaudio disabled?

I'm running KDE and, yes; I did run all commands as root (well, to be specific, using the su command). I'll try again, just to make sure.

I logged as root and did all the steps again...nothing; still no audio. This is weird?!

I don't use Mandriva,but in KDE when I click on the volume icon(Kmix)there's a master channel,so I don't know why you don't have that option,maybe you should install/reinstall Kmix because maybe it's another app that you have there.If I were you I would uninstall pulseaudio completly and run only alsa(but do this as a last option).
You can create new user and add him to the audio group and see will the sound work for that user then.Here's something I just found;
Then move .kde to .kde_old and check if you have sound then.

I'll give it a try. Something I noticed is that when I run Mandriva from the liveCD it doesn't have sound either. But with a Mandriva 2008.0 liveCD I have sound without problems.

I was also thinking about recompiling ALSA from the source to see if it works. Never done it, but seems like a good time to learn...

Hi, using kde? I also use alsa, because I had no sound with pulseaudio.

Generally when I need to set or change the settings of the "sound system" I use the "kde control centre".

Here (hardware) you can make sure the system is enabled, set the bit rate and sample frequency, and (general) timeout after non-use to release the resources it was using.

if you have no joy, you could check "lspci" in a terminal (even lspci -v for more info) to confirm your hardware.
You could also check lsmod and see if the modules are connected.

making sure these are listed is a first step.

see how you go, regards Glenn.

Hi, you could also check the above with the 2008.0 ONE cd to see which modules are loaded and where.

It may give some insite.

My modprobe.conf only references sound as, alias sound-slot-0 snd_hda_intel

There is no other mention in the other modules files. (/etc/modprobe.preload, and /etc/modules)

Ok, the output of lspci -v (only included soundcard's info and omited the rest):

Everything seems normal (and very much alike your configuration, I must say). Any suggestions?

No, It seems that the hardware and kernel are OK.

have you tried the modules edit I have listed above? (to /etc/modprobe.conf)

Also make sure you leave a blank line at the bottom of the file before you save it, some config files require this, or they just don't work. (EOF) You can comment lines, so they don't get used with a hash #. Good for quick debugging.

Not very technical, sorry, as an alternative you could research mod, modprobe, insmod, rmmod, etc.. Check that any docs you find on this are up-to-date, as there have been some changes and some "popular" docs are quite old and outdated. (hence, my sparse knowledge on the subject)

You may need to reboot for the changes to be effective, I think your problem is with either...

speakers in wrong socket, should be green on most pc's.

or the sound manager is not connecting to the Desktop (kde, gnome).

Another thing to check, is the sound daemon loading? from the star (application launcher) menu, go to "Tools/System Tools/Configure Your Computer"

you need to be root.

go to "System/Manage system services..."

make sure alsa and sound are on, (forgot pulseaudio, pulseaudiod, diable it if you see it there.)

you can test these from here, you get an output that may reveal the error.

see how you go, Glenn

ps, other places to look,
/etc/sysconfig/pulseaudio
/etc/X11/xinit.d/50pulseaudio
/etc/xdg/autostart/pulseaudio-module-xsmp.desktop
/etc/pulse
/etc/pulse/client.conf
/etc/pulse/daemon.conf
/etc/pulse/default.pa
/etc/sysconfig/pulseaudio
/usr/bin/pulseaudio
/usr/lib64/pulse-0.9/

Ok, my modprobe.conf has that line you mentioned already (alias sound-slot-0 snd_hda_intel).

This is a Toshiba Satellite A105 S2011 laptop with integrated speakers, so the "speakers in wrong socket" suggestion doesn't apply.

Checked the sound daemon, and both alsa and sound are running from startup. Pulseaudio doesn't appear, as I disabled it already.

Well, still no sound. Any other suggestions? Anyway, thanks for your time GlennsPref, you've been very helpful so far.

I'd check all this stuf with a live cd that gives me sound.

Then copy or email some of the files. Can you access your drives with a live cd, with root privilege?

I use a mepis 6.0 live dvd, it's quite good as far as privleges, but can only access one harddrive(sda) at each boot.

Check the mandriva hardware list?

That's all I got.

regards, Glenn

ps, another program that can mess up the sound is arts, artsd. You may want to check the settings there, also if you have qjackctl installed, check the config for that as well. GW

Try to set the sound-slot, tyr 1 and 2 . can't hurt to try.

Glenn.
