Still No Sound - What Can I Try Next?


I have tried installing Slack 9.1, Mandrake 9.2 and now Fedora Core 1 and 1.90. On every I cannot configure the sound

My soundcard was recognised as:
NVidia nForce 2, CHIP: Avance Logic id60, ITEM: CD.

lspci:
00.06.0 - multimedia audio controller: nVidia Corporation nForce2 AC97 Audio Controller (MCP) (rec a1).

Also found:
Sound driver: 3.8.1a-980706
Card config: Nvidia nForce2 at 0xe0001000, irq11

I have checked all 3 plugs on the motherboard, tried adjusting all setting such as KMix, Alsamixer, application volume settings.

Has anybody else experienced this problem and can offer some potential solutions to try?

I know that I had problems with my Avance soundcard but I dont think it was the same one as yours. Anyware my problem was that I couldnt get sound or anything. After some trail and error I realized it was the ALSA driver, so I used swaret to get an older ALSA driver and It worked fine.

Also to point out the obvisious. Have you made sure the it was unmuted? Open ALSA and if it has "MM" on the volume bar then the card is muted and you can fix this just by pressing "M" on the volume bar that is muted.

I have tried adjusting the settings in Alsa. Still no luck.

Any other ideas to trace to the source of the problem?

Over the weekend, I was able to locate some further information on the problem (possibly! - hopefully) ...

When booting, the following message came up:

requset_module: failed /sbin/modprobe --snd-car-0 . error=256
PCI: setting latency timer of device 0000:00:06.0 to 64
intel8x0: clocking to 47426
request_module: failed /sbin/modprobe --snd-card-0. error=256

I am not sure if this is the error that explains why the sound is not working? I hope someone can help me out.

Sorry, I could only tell you what I knew from having similar problems. We really need someone who can interperet that information in here.

Modules.conf settings?

Hmm... "Sounds" like (no pun intended) a problem with something that's in "/etc/modules.conf". Have you been over to the ALSA web site to see what the recommended "modules.conf" settings are for your sound chip/card?

I reviewed the information for Nvidia sound cards on the alsa website. I tried reinstalling alsa following the precise procedure, however the modprobe command in Fedora Core 1.90 was not recognised (?). I opened alsamixer and checked all the settings, but my CDs were still silent

The following message appeared during login:

'International-artsmessage'
Sound server informational message:
Error while intializing the sound driver:
device /dev/dsp can't be opened (No such device)
The sound server will continue, using the null output device.

Not exactly sure what this means.

HOWEVER I thought of some ideas ...

Would the 5.1 channel PCI card cause the difficulties in setting up my sound?

If I remove that PCI card, could that cure the problem (I dont need 5 channel)?

Alternatively, I could just buy a new PCI sound card - would that fix my problems?

Not surprised given that card initialization is not working.

Try looking in the /dev subdirectory. There should be several dsp devices (dsp0-dsp3 on my RH8.0 system). While in /dev, try issuing the command "ln -s dsp0 dsp". Then reload the modules using a command like "modprobe -a". If the modprobe error goes away, you may be out of the woods. I'm guessing that your modprobe.conf file references /dev/dsp which doesn't exist. You can either add the symbolic link or modify the sound card entries in modules.conf to reference dsp0.

ALSA is supposed to be able to support multiple sound cards from multiple vendors though I have direct experience in making this work. So... I don't think you need to remove the 5.1 card. There are (or at least, used to be) examples of how you'd configure a multi-card setup on the ALSA web site. And, no, I don't think it's time to consider buying a new sound card.

I'd try the symbolic link in /dev first. The modules.conf entries can be a bit tricky (maybe it gets easier with practice but how often do you mess with this stuff, eh?) so pay special attention to the spelling, etc. in those entries.

Good luck,
Rick

Thanks Rick. I've printed out your email from work and will take it home tonight and try and work through the problem.

Yikes!

I just read what I posted earlier and saw a nasty typo. It should have read "I have NO direct experience in making this work" (multiple sound cards, that is). Odd how stuff like that gets through the proofreading. Sort of like not seeing a "the the" but dropping a "no" is not quite the same thing. Sorry to disappoint anyone who might have thought I'd be any help there.

I haven't used the Nvidia chipset yet but we ought to have you hearing Linus pronounce "Linux" before long. BTW, I looked on the ALSA site at the modules.conf settings for the Nvidia card and I saw nothing in there about /dev/dsp (vs. /dev/dsp0). I did a little bit of grepping in the driver code shows that "/dev/dsp" is referenced in several places. So my thinking is that you might, for some strange reason, just be missing that symbolic link in /dev. FWIW, my RH8 system has the link and it's got the same timestamp as the dsp[0-3] special files. (Maybe you're just seeing an RH9-ism.)

Let me/us know what you find in your next attempt.

Good luck,
Rick

SUCCESS!!!

It is a little hard to report back on the findings when I don't have my internet access at home on my linux desktop - I applied for ADSL with iiNet in Australia and have a 6 week wait until it is connected

However, I checked the links to dev/dsp and couldn't see any - there were references to null output that didn't look correct.

Anyway, I had also printed out the ALSA config help pages from their website.

My Fedora Core kernel did not have the soundcore module (?). I tried recompiling my kernel with the module, but still couldn't find that module.

After that, I did a quick Slackware 9.1 install. Ran through the ALSA help pages, loading up the intel8x0 module. Installing all the three ALSA files. Rebooted, slipped in a CD, checked the output from the motherboard and on trying the blue output - MUSIC!!!!

We have sound. Looks I am going to be a Slack-man. I hear a lot of people saying that Slack is not user friendly, but I always seem to have the least problems and highest rate of problem-solving success with Slack.

Ah... I recall schlepping a lot of stuff back and forth between work and home via DDS tapes (or +AGA-split'ing tar archives and rpm files and stuffing the pieces onto floppies before I had the tape drive working) before getting access at home.

Bet that +AGAAYA-null output'' had a recent timestamp on it.

Dunno much about Fedora. My guess would be that the kernel build process would be very similar to Red Hat's. As I recall, all I had to do for sound was request modular sound support and turn everything else off. The ALSA driver build took care of the rest.

I started out with Slackware (came in the back of a book on a CD). I remember having to grab the floppy boot images from the CD and make real boot floppies as my old '486 wouldn't boot from a CD-ROM drive (this was back in about '94). It was a good distribution to learn on. Read a lot of man pages in order to figure out how to configure everything. Fond memories of those times. Except for the XFree86 setup of that era. That was no fun at all. I was not concerned about sound on my PC at all in those days.

Anyway, glad to hear that you're making noise with your PC now.

Have fun,

Rick
