i do not think u need alsa support the way u did

there is alsa suport integrated in the kernel itself

so why don't u remove those packages

After you installed the new ALSA drivers, you have to restart alsa or reboot the computer. As su - or root type service alsa restart. The script service will run the alsa script to unload the alsa modules and load them up again. Hopefully, the Fedora community did not throw out the System V init scripts or you have to unload the sound modules by hand.

The alsa documentation for the module does show example code to include in /etc/modprobe.conf. Go to http://www.alsa-project.org/alsa-doc...odule=intel8x0 and look for "Setting up modprobe and kmod support".

Try using aumix if alsamixer gives you nothing.

Code:

This means either the module nvsound is handling the device or it is already loaded.

If you want to use the driver from nVidia only use:

Code:

alias eth0 nvnet

alias usb-controller ehci-hcd

alias usb-controller1 ohci-hcd

alias ieee1394-controller ohci1394



# Loads nvsound (OSS only)

alias sound-slot-0 nvsound



# Sets nvsound mixer settings

install nvsound /sbin/modprobe --ignore-install nvsound ; sleep 1; /usr/bin/nvmix-reg -f /etc/nvmixrc -L >/dev/null 2>&1 || :

remove nvsound { /usr/bin/nvmix-reg -f /etc/nvmixrc -S >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove nvsound

If you want to use driver from alsa only use:

Code:

alias eth0 nvnet

alias usb-controller ehci-hcd

alias usb-controller1 ohci-hcd

alias ieee1394-controller ohci1394



# ALSA portion

alias char-major-116 snd

alias snd-card-0 snd-intel8x0



# OSS/Free portion

alias char-major-14 soundcore

alias sound-slot-0 snd-card-0



# card 1

alias sound-service-0-0 snd-mixer-oss

alias sound-service-0-1 snd-seq-oss

alias sound-service-0-3 snd-pcm-oss

alias sound-service-0-8 snd-seq-oss

alias sound-service-0-12 snd-pcm-oss

For flexbility, use ALSA.

When using nvsound, you have to use nvmixer. Also make sure you have at least version 3.1 libraries for QT because the nvmixer uses it. All the information about nVidia sound driver is at http://download.nvidia.com/XFree86/n...easeNotes.html or in the driver.

You should not place .asoundrc in /root directory because it will not get used by anyone but root. You have to put it in the user's directory.

BTW, I do not have an nForce board, so the information I got was from the ReleaseNotes file.

You do not need to run snddevices. RTFM!

Code:

alias /dev/mixer snd-mixer-oss

alias /dev/dsp snd-pcm-oss

alias /dev/midi snd-seq-oss

This is wrong. Sheesh I gave you the lines and you insulted me when using someone else lines which did not work. :mad:

Read http://www.alsa-project.org/alsa-doc...odule=intel8x0 it will tell you how compile them. Using a program like yum-install will not work well.

Installing ALSA is very, very easy. I lost count how many times I successfully installed it. If you want to use someone else instructions other than what I gave you, thats fine. Usually they are wrong.

BTW, post your modprobe.conf file.

Why u edit and erase what you posted?

LloydM -- it's not entirely clear what the background is with this thread, but the purpose of the edit function should be to make minor modifications to an existing post rather than to erase the entire contents of the post. Unfortunately, as it now stands, this thread is pretty much useless given that there's only one half of the discussion remaining. I'm not sure what your reason for doing this was, but I'd ask that this not be repeated. Thanks -- J.W.

I think this thread could've been useful for me :cry:

I have an nForce3 MB and useing nvsound driver and useing the configuration from the readme, but some programas tell me that they can't use /dev/dsp and it seems that this is not posible with nvsound and the the conf from the readme...

So... what should I do?
Should a get back to intel8x0 an use

Code:

# ALSA portion

alias char-major-116 snd

alias snd-card-0 snd-intel8x0



# OSS/Free portion

alias char-major-14 soundcore

alias sound-slot-0 snd-card-0



# card 1

alias sound-service-0-0 snd-mixer-oss

alias sound-service-0-1 snd-seq-oss

alias sound-service-0-3 snd-pcm-oss

alias sound-service-0-8 snd-seq-oss

alias sound-service-0-12 snd-pcm-oss

And then make a .asoundrc?? Or is there a way around to keep the OSS nvsound driver with multiple applications shareing /dev/dsp??

I think I get stronger sound with nvsound but missing the /dev/dsp stuff...

HellSpawn - unfortunately I think it's best to create a new thread, as this one does not have much use anymore due to the removal of the original and followup posts. Due to these factors, I have decided to close this thread.

In terms of addressing your issue, one thing to check would be to verify that the permissions on /dev/dsp and /dev/mixer are appropriate (they should be 666) -- J.W.
