Well, we're getting there.
And it's no trouble to me at all. Your modules.conf file looks good.
Did you uncomment the line in your /etc/rc.d/rc.modules file? I know you said you did this already, but I'm just covering all the bases.
It should look like this under your Sound Support section (you've got some scrolling to do to get there):
### Sound support ###
# Sound Blaster Pro/16 support:
#/sbin/modprobe sb io=0x220 irq=5 dma=3 dma16=5 mpu_io=0x300
# Sound Blaster Live support:
# MAD16 support:
#/sbin/modprobe mad16 io=0x530 irq=7 dma=0 dma16=1
# AD1816(A) sound driver:
#/sbin/modprobe modprobe ad1816 io=0x530 irq=5 dma=1 dma2=3 ad1816_clockfreq=330
# Crystal CS4232 based (PnP) cards:
# ES1370 support, such as Sound Blaster 128PCI:
# ES1371 support, such as Sound Blaster 64V PCI:
# ESS Maestro, Maestro2, Maestro2E:
# ESS Maestro3/Allegro:
# (For information on configuring other sound cards with Linux,
# see the documentation in /usr/src/linux/Documentation/sound/,
# and /usr/src/linux/Documentation/Configure.help.
Notice how the only line uncommented (no # at beginning of line) is the emu10k1 line? That's how yours should look.
When you say that the "soundcard is only accessible to root", what exactly are you referring to? I know this sounds like a goofy question, but I'm trying to figure out where this info came from. When you do a "ls -l" for /dev/mixer and /dev/dsp does it look like this?:
phyx@frankenstein:~$ ls -l /dev/mixer
crwxr-xr-x 1 root sys 14, 0 Jul 18 1994 /dev/mixer
phyx@frankenstein:~$ ls -l /dev/dsp
crwxr-xr-x 1 root sys 14, 3 Jul 18 1994 /dev/dsp
If not, chmod 755 both of them again to make sure. Other than this, the only thing I can think of is to check your volume levels. I never asked this before either and I should have--when you say you have no sound, are you getting no sound at all or no sound when trying to play a CD? If it's when trying to play a CD, go into X and load up your XMMS or whatever you're using. Check to make sure that your volume level is up. Also, go into Kmix (if in KDE) or Audio Mixer (if in Gnome) and make sure that your volume levels are up and also not muted or shut off. If it still doesn't work, let me know and we'll see what else we can think of.
