I have /etc/modprobe.conf. but look at this,

root@darkstar:/home/greg# ls /etc/modprobe.d
blacklist isapnp modprobe.conf sound


no alsa-base, but another modprobe.conf. and whats this 'sound'?

root@darkstar:/home/greg# cat /etc/modprobe.d/sound
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel



I tried all 3 combinations of the, 'options snd-hda-intel model=' statement. that was in /etc/modprobe.conf. I'll try 'sound' and if that doesn't work /etc/modprobe.d/modprobe.conf.

Anyway, I can't for the life of me understand how the fix would be this simple... here's to hopin!

um I can not see your contents of modprobe.conf...but the link says its ok not to have the alsa file.

so insert in turn the following lines into /etc/modprobe.conf there are 4 to try.

options snd-hda-intel model=3stack
options snd-hda-intel model=toshiba
options snd-hda-intel model=acer
options snd-hda-intel model=auto

2) the alias are normally ok but you have 2 and I only have in modprobe.conf
alias sound-slot-0 snd_emu10k1....so make a backup of the current file then
as its only sound that is playing up you have nothing to lose to try each new hdaintel line with a reboot but change your alias lines by deleting snd-card and keep the sound-slot


3) Can you be more explicit...are you saying you have
/etc/modprobe.conf
/etc/modprobe.d/modprobe.conf

one might be a symbolic link to the other.

ls -l /etc/....blah blah to test both pls

BTW I have /etc/modprobe.d....but it has no modprobe.conf

I wonder, if I am reading you correctly, you have 2 conf files that don't know if they are arthur or matha? ...I am suggesting....disable the read write permissions to any conf file sitting in /etc/modprobe.d/ pls

"create files in the /etc/modprobe.d/ directory containing modprobe options."

So I think I should be editing /etc/modprobe.d/sound

I'll try this before doing the realtek driver thing.

I tried all 4 "options" statements in /etc/modprobe.d/sound. But my computer continues to silently mock me.

Next I installed the realtek driver. The driver added two more faders under alsamixer / kmix. in kmix they are listed as output's 'mic boost' and 'front mic boost'. still no sound, still no led for pcm in alsamixer or kmix.

This is frustrating. I'll read the rest of these threads after I've cooled off a bit.

In the mean time, thanks for your help I really do think that I'm closer to getting it, and if you have any idea's let me know. I'll post the solution on here if I ever find it.

okay, so I added "options snd-hda-intel model=hp" to "/etc/modprobe.d/sound " _again_ after installing the realtek driver (this file: ftp://202.65.194.212/pc/audio/realte...-4.07b.tar.bz2 , from this site: http://www.realtek.com.tw/downloads/...Audio%20Codecs )

and I can hear the moon light sonata gloriously coming through my laptops speakers.

So on my HP DV9000 w/ slackware 12, I installed the above mentioned realtek driver, and my /etc/modprobe.d/sound reads as follows:

greg@darkstar:~$ cat /etc/modprobe.d/sound
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=hp

Thanks for all the help aus9.
I hope this thread helps other people w/ this make / model of PC get linux running.

if you are still following this post...thanks for showing pppl how you fixed it.

did you try to delete one of the alias lines?

Before installing the realtek drivers, I removed the 'options' statement from my modprobe.conf and modprobe.d/sound because I didn't think it was helping.I did not modify any of the alias statements tho.

Once I went back into modprobe.d/sound and added the options statement + rebooted, it worked like magic

It should also be noted that PCM still has no mute option, and I think thats the way it's supposed to be. I have two 'front' channels (or faders) which reflect left and right speakers that are built into the laptop, these can be muted. PCM can never be muted however... seems weird to me, but I am sorta a noob :P

well that may be true for your specs but not mine
