No soundcard detection

oxman · 08-03-2004, 10:46 PM

I've been running RH 9 for some time with no sound problems. After installing Fedora Core 2 my sound card (opl3sax) is not detected and I have no sound. Alsa drivers support the card.
After running modprobe snd-card-opl3sa2 I get :

FATAL: Module snd_card_opl3sa2 not found.

If I do soundcard detection I get:

No sound cards detected

Any help would be greatly appreciated.

Can you post the output of lspci please?

I have been wanting to for years. Thanks for the reply.

Below is the lspci print:

OK. Could you now please post the output of lspci -v? It seems that your sound card is not getting picked up by the PCI bus. This is the output of lspci on my computer and I've bolded the important bit:

Code:

0000:01:08.0 Ethernet controller: Intel Corp. 82801BD PRO/100 VE (CNR) Ethernet Controller (rev 81)

You seem to be missing that bit (that I've bolded). If nothing like that comes up under lspci -v then try the following:

1. Make sure your card is properly inserted into the PCI slot. Possibly take it out and put it back in.

2. Use a different PCI slot.

3. Take your card out, clean the connectors with something like ethanol, methylated spirirts, methanol, isopropanol, etc. Do not use water, acetone or any petroleum based products.

4. If all of those fail, try booting another OS (if available) or putting the card into another computer to see if it gets detected.

Well there are a lot of tutorials and HOWTOs out there. I suggest trying those. There is a good one here. It's actually not as hard as some people make it out to be. I didn't use any tutorials and it worked just fine. If you have already tried and failed then you'd have to specify where you failed and what (if any) error messages you got.

oxman · 08-05-2004, 11:33 AM

Thanks for the reply mate!

Nothing even comes close to your code. Fedora is just not picking up my sound card. The card is now working quite well in another OS and did quite well in RH9. I wish I would have backed up /etc of RH9.

Thanks for the lead on the tutorial.

OK. Can you go to /lib/modules and do a find -iname *opl3*. Then try modprobing any modules that come up.

If that fails then I'm out of ideas. It's strange that the card would not get picked up by Fedora since I always thought that the lspci code was the same everywhere. Usually, if Linux doesn't know what it is it just prints "unknown device" but still gives the vital statistics.

oxman · 08-05-2004, 11:30 PM

adz, thanks so much for your time. Here's what /lib/modules and do a find -iname *opl3* gives me.

Code:

./2.6.5-1.358/kernel/sound/isa/snd-opl3sa2.ko
./2.6.5-1.358/kernel/sound/drivers/opl3
./2.6.5-1.358/kernel/sound/drivers/opl3/snd-opl3-synth.ko
./2.6.5-1.358/kernel/sound/drivers/opl3/snd-opl3-lib.ko
./2.6.5-1.358/build/sound/drivers/opl3
./2.6.5-1.358/build/include/config/snd/opl3
./2.6.5-1.358/build/include/config/snd/opl3sa2
./2.6.5-1.358/build/include/sound/opl3.h

Looks like the drivers are there to me. I'll just have to keep at it.
Thanks again.
Stanley

adz · 08-06-2004, 09:36 AM

well, above you stated that you used the command modprobe snd-card-opl3sa2. If this is not a typo then you should have typed modprobe snd-opl3sa2. Try that and see what happens.

oxman · 08-06-2004, 10:19 AM

Well, I guess that's progress. Instead of the "FATAL" I just get # and a flashing curser with no print out? when doing > modprobe snd-opl3sa2

adz · 08-06-2004, 08:41 PM

Does sound work after that? Does snd-opl3sa2 show up in the output of lsmod? Does anything change in lspci?

oxman · 08-07-2004, 01:13 AM

greetings again adz and thank you.

Still no change in performance. The sound card is not detected. One thing did change though and that was the lsmod print out. Here it is:

Code:

snd_opl3sa2            13284  4
snd_opl3_lib            7424  1 snd_opl3sa2
snd_hwdep               6276  1 snd_opl3_lib
snd_cs4231_lib         18948  1 snd_opl3sa2
snd_mpu401_uart         4864  1 snd_opl3sa2
snd_rawmidi            17184  1 snd_mpu401_uart
snd_seq_device          6152  2 snd_opl3_lib,snd_rawmidi
snd_pcm                68872  2 snd_opl3sa2,snd_cs4231_lib
snd_page_alloc          7940  2 snd_cs4231_lib,snd_pcm
snd_timer              17156  3 snd_opl3_lib,snd_cs4231_lib,snd_pcm
                                                                                
snd_mixer_oss          13824  2
snd                    38372  14 snd_opl3sa2,snd_opl3_lib,snd_hwdep,snd_cs4231_lib,snd_mpu401_uart,snd_rawmidi,snd_seq_device,snd_pcm,snd_timer,snd_mixer_oss
soundcore               6112  3 snd

One peculiarity is that my first printout was

Code:

snd_opl3sa2            13284  0

After redoing the lsmod it changed to 4

Also the gnome alsa mixer recognizes the card but gives me no options to open a file

adz · 08-07-2004, 03:20 AM

Does anything change in lspci? Post the results again, please (after inserting the modules).

Also, did you install the alsa-libs and alsa-utils (they will be available from the same place you got the drivers)? If not, then do so. Once you have done that run an app called alsamixer and raise all the levels to something close to 100% and try to play a sound. Preferably not an audio CD.

oxman · 08-07-2004, 07:31 PM

argh!!!! I just rebooted and lost all of the sound again. Going to the alsamixer shows that the default settings are back where they were. There are no changes in lspci. and lsmod shows only 0 as user for snd_opl3sa2. Do you think it's a permissions problem? Can't see that because i tried logging on as root and still no joy? I reset the alsamixer as root and I have the CD again etc.

There are no changes in lspci. The drivers modules are not being loaded. Can you make anything of it?

adz · 08-07-2004, 09:35 PM

I assume since you're using alsamixer that you have the alsa libs and utils installed.

Quote:

Meaning what exactly? They've gone back to zero/muted? That's normal behaviour. There is a way to save your settings with alsactl but don't worry about that yet.

Quote:

Do you think it's a permissions problem?

No I don't think so. But to be sure make sure you're part of the group that has ownership over the sound devices. In Debian it's the "audio" group.

Quote:

you don't need to do it as root and what CD are you talking about? I said test the sound with something other than an audio CD.

Quote:

I don't understand. First you say snd-opl3sa2 shows up in lsmod (and is therefore loaded) then you say that the driver modules aren't loaded. Which is it?

oxman · 08-08-2004, 12:42 AM

yes the alsa libs and utils are installed

xmms plays ogg files

modules must be loaded then. just the sound card is not detected? i assumed that if the sound card is not detected the modules wouldn't be loaded. The system sound card detection utility says, "no sound card detected".
