Nvsound: Unable to open the Mixer

[pergamon]

Hi!

I'm getting quite tired of this now, recently I had some major problems while getting JOGL (openGL with Java) to work on my Nvidia card. Finally got it to work on my second computer (which I normally only use for music and movies) by reinstalling Slackware 10 on it.

Before I reinstalled I had hw support with 5.1 surround on its' NForce2 internal audio. Now I can't open nvmixer without getting errors. What I can see I have the same settings as before, but apparently not....

This is the message I get.
Nvsound: Unable to open the Mixer
Nvsound: Unable to open the Mixer
Nvsound: Unable to open the Mixer
Nvsound: Unable to open the Mixer
Nvsound: Unable to open the Mixer
Nvsound: Unable to open the Mixer
Nvsound: Unable to open the Mixer
etc.

Anyone seen this? Know how to make it work?

In /dev i dont seem to have any audio devices (maybe Nvidia0, Nvidia1, Nvidiactl) but no dsp, mixer etc.

please help.

I have the same problem using nForce4 motherboard :-/
I'm on Ubuntu Hoary PR.

Hi there

I think you might find all your audio devices in /lib/dev-state/sound

I did after an hour and a half of trying to get nvsound to work

I'm having the same problem, and nope I didn't find them in /lib/dev-state/sound. I'm also using Ubuntu Hoary. I actually get sound through ALSA, through my headphone jack, out of the box. But I need the spdif output to work. Any help would be appreciated!

I have a Fedora Core 4 (kernel Linux 2.6.14-1.1644) on a Athlon 64 4000+ and an ASUS A8N-SLI (nForce 4 SLI chipset) and I installed NFORCE-Linux-x86_64-1.0-0310-pkg1.run and configured my /etc/modprobe.conf as described in the NVidia instructions, but I hear no sound at all.
I cannot event start nvmixer because if I try to do that, I receive the following error message:
nvmixer: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

But I have all the legacy libstdc++ library installed, as shown below:

$ ll /usr/lib/libstdc++*
-rwxr-xr-x 1 root root 258288 8 mar 2005 /usr/lib/libstdc++-2-libc6.1-1-2.9.0.so

Can someone help me?

Thank you very much.

Please post the output from the following commands:
rpm -q compat-libstdc++
ldd `which nvmixer`

And also post an nforce-bug-report.log

Thanks,

This looks like a GCC update conflict to me. You will get conflicts with libstdc++.so.5 and libstdc++.so.6 depending on what you built with what GCC and what libs are called in/required.

I just been through all this with building KDE3.5 - QT squinnied as it needed GCC libstdc++.so.5, and not libstdc++.so.6. I rolled back to origianl GCC and all built/works perfect.

Updating GCC can be dangerous (as I found out).

I'm also having the same problem as diffid and IdoMcFly. I'm running Ubuntu Breezy.
The nvsound module seems to load just fine but there is nothing for the card under /dev (no /dev/dsp)

I checked in /lib/dev-state/sound but this directory does not exist, I'm also not sure why they would but a device driver node there.

Here is a link to my nforce debug file:

Does anyone have any suggestions on what I should try next? I made sure to compile the VFORCE module with gcc-3.4. The nvnet module works great.
Why wouldn't udev make the link at /dev/dsp if the module loaded correctly?
