No sound of any description from nVidia integrated soundcard. Why?

allforcarrie · 11-18-2004, 01:37 AM

i was having the same trouble i guess mandrake doesnt support nvidia base audio...... mine just started working.... it was wierd.

xxvm1 · 11-18-2004, 07:49 AM

i'm now getting loud crackling from my speakers with normal found faintly in the background.

I think i'm damned to never have proper sound

turn your wav volume down and speakers up.

xxvm1 · 11-18-2004, 12:26 PM

How do i turn WAV volume down? Mandrake 10 appears to have no kind of volume controls.

Wyk3d · 11-18-2004, 02:40 PM

-Try using the 'alsamixer' command for volumes.

Alsa not loading on boot can have several causes. First you should check these:

1) Check if when booting mandrake you get 'Loading sound module [OK]' and a 'Loading mixer settngs [OK]' messages.
2) Before and after you start alsa from mcc you should run the following command and compare the output:
'lsmod | grep snd'
(post the two outputs)

There may be several ways to solve this but i should see these results first.

turn labels on in mixer and adjust the wav volume or just mess around with levels.

xxvm1 · 11-18-2004, 06:10 PM

Before ALSA was started in MCC:

snd-usb-audio 68064 0
snd-rawmidi 24288 1 snd-usb-audio
snd-seq-device 8232 1 snd-rawmidi
snd-pcm 99300 1 snd-usb-audio

snd-timer 25604 1 snd-pcm

soundcore 9664 1 snd
usbcore 104604 6 hid,snd-usb-audio,ehci-hcd,ohci-hcd

After ALSA was started in MCC:

snd-seq-oss 34112 0

soundcore 9664 1 snd

I've used the alsamixer command and messed about with the volumes in there a bit randomly and it seems to have taken away the crackling for now. I don't know if the above provided pastes are any good but have a look and see if you can get an idea of what's going on.

Thanks for the patience and helpfulness.

Wyk3d · 11-19-2004, 02:04 PM

Ok this shows that the audio modules are not loaded before starting it from mcc, but this was predictable, I just wanted to be sure. The first question was actually more important. Please answer all these questions because i need a lot of information to solve a problem.

I asked if you see the 'Loading sound module [OK]' and 'Loading mixer settings [OK]' when the system boots (in verbose mode). You might not see these or you might see a failed.

Now the rest is actually quite complicated as there are several things that need to be checked.
To have you do this remotely is not really possible so you would need someone over there who knows the basics of shellscripting.

If you don't see these then:
On my mandrake 9.1 the /etc/rc.d/init.d/sound file has an error and it loads the module but doesn't load the mixer settings i had to solve this by commenting the right lines. What has to be done is adding 'echo test;' lines and to keep running the script to see if execution gets to the specified pont. If you find an if statement that doesn't allow the modules from being modprobe-d you should either comment things so that the only the correct part of the if gets executed or change the test string to something that always gives 'true' (or 'false' depending on whether it's in the 'else' or the main part).

If you do but these fail then:
Check /etc/rc.d/init.d/sound for the command that fails by using the same 'echo test;' lines to find the line where the error occurs.Manually run that command and check the man page for the command or search the net for the returned error message.

If they do appear and don't fail then:
(There is a brutish solution but it might work and it isn't too hard to do)
The modules are not being loaded so we're going to add the modules to the system boot modules list.
-vi /etc/modules
-add the following:
snd-seq-oss
snd-seq-midi-event
snd-seq
snd-pcm-oss
snd-mixer-oss
snd-intel8x0
snd-ac97-codec
snd-mpu401-uart
-save and reboot

Anyway glad to have helped.

I don't suppose switching distros would give me any better luck ?

Hmm, sound-slot-0 is occupied by your SiS Pci SoundCard, all the modules are loaded as necessary and nothing is using the /dev/dsp. So you're ok to go.

I think, all you need to do is run the audunmute script to unmute thing and mess around with alsamixer to get the volumes you desire.
If this doesn't help then post any error messages or any other symptoms that you get.

Xxvm1

There are many nice distros out there and you would definitely find one that sets up your sound card well. BUT until you aren't fully acquainted with linux inner-workings i suggest you stick to mandrake because it's THE best distro for home use.

Did you check the boot messages ? You should really try that last part i wrote after 'If they do appear and don't fail then:' That just might solve you're problem and as you already know 'vi' this shouldn't be too hard.

Hope this helps..
Steve

dolphans1 · 11-20-2004, 07:44 AM

Wyk3d,

Prior to running into your thread here, I tried configuring ALSA and missing around with the slidders and that did not work, then I did a search on here and found this thread.

I am confused on how I run the audunmute script.

This is the section you wrote on it:

Code:

- If all is ok all you nee to do is to run the unmute script (audunmute):
 amixer set PCM 22 unmute
 amixer set PC\ Speaker 22 unmute
 amixer set Master 22 unmute
 amixer set Master\ Mono 22 unmute
 amixer set Headphone 22 unmute
 amixer set Phone 22 unmute
 amixer set Aux 22 unmute
 amixer set Video 22 unmute
 amixer set CD 22 unmute
 amixer set Input\ Gain 22 unmute
 amixer set Line 22 unmute
 amixer set MIC 22 unmute

How do I run that scirpt? What is the exact command I enter? I tried ./audunmute and got bad bash command.

I have tried in superuser mode and do not know what else to do.

I appreciate your help.

d-1

Ok i've edited my first post so it's a bit easyer to understand. (read it again please)
