nvsound on an lfs build

behmjoe · 12-07-2005, 02:21 AM

Hi,

I built and lfs using the cvs version. I am trying to get the nvsound module from the nvidia site working. I can play mp3's as root, but when I switch to a regular user it won't play. Can anyone help me?

thanks.

Do a as root

Code:

chmod a+rw /dev/mi* /dev/dsp* /dev/seq*

Code:

chmod 777 /dev/dsp*; chmod 777 /dev/mixer*;chmod 777 /dev/pcm*

I did nothing there.
You have to install the ALSA packages from BLFS:
This is what I installed
ALSA Library-1.0.9
ALSA Utilities-1.0.9a
ALSA OSS-1.0.9

You also have to put some OSS emulation modules in the [b]/etc/sysconfig/modules/

Code:

# Sound Modules
snd-pcm-oss
snd-mixer-oss
snd-seq-oss

Then I did the chmod thing.
then I played a bit with alsamixer and I had sound.

Hi

Yes, but as soon as I reboot the permissions will change back to what they where using udev.

Hi,

did you use a kernel native driver or the driver from the nvidia site. The driver from the nvidia site is a oss driver, and not an alsa driver. If you used a kernel native driver which one did you use?

thanks

Correct.
you need to edit the /etc/group file.
It should contain
audio:x:11:<your_username>

like
audio:x:11:mr_demilord

Save the file and reboot.

The problem was that you should be a member of the group audio
