I have run into a problem after compiling a new kernel where I do not have any sound in KDE or anywhere else for that matter. I am using 2.6.1-gentoo. This is a fresh install of gentoo, I was not upgrading kernels. I have gotten this soundcard to work under debian before though. Just having problems with kernel 2.6.1 under gentoo and kde. It appears the card is detected and I have compiled all my sound card options into the kernel(2.6.1), as shown below. No sound card modules are being loaded.

heres what I got from kernel bootup...

Advanced Linux Sound Architecture Driver Version 1.0.0rc2.
request_module: failed /sbin/modprobe -- snd-card-0. error = -16
specify port

ALSA device list:
#0: Sound Blaster Live! (rev.6) at 0xc800, irq 10

it looks like its not detected but it is...I did alot of googling on the /sbin/modprobe --snd-card-0 error but nothing there helped me.
some more info....

I get into KDE and run the aRts control tool which is i guess is an interface to ALSA. If i run XMMS or Noatun and play an mp3, i can see the volume sliders on the aRts control tool go up and down. I am 100% sure the sound card works, as it outputs sound in windows xp. I am sure its hooked up to the right speaker outputs. I am at a loss, it seems it should work but it doesnt.

Any ideas?

Have you tried messing with the volumes in KMix ( Under multimedia ) as Switching to a 2.6 kernel and alsa can be mean that some of these are reset too 0. when you need them higher. Check both Input and Output. These are the important ones

Input: Surround Digital, Wave, IEC958TTL, CD, Line
Output: Master, PCM, AC97, EMU10K1 PCM, EMU10K1 PCM Send.

wow, what an easy fix lol, thanks alot for the help!

Any idea's about that

/sbin/modprobe error? I am guessing i dont even need that...if so, how would I go about removing that line from my bootup scripts?

Modprobe is looking for a module you've compiled into the Kernel. So you get an error.

If you wish to switch between kernels, You'll have to leave it in so the Older kernel continues to work ( as they both usually use the same list ). If you don't want to switch between version look for a file /etc/modules Theres usually a list of kernel modules to load on booting. Although Gentoo maybe different.

thing is there is nothing about it a module snd-card anywhere in my modules.conf or in the modules.d directory. theres no reference of it in any of the bootup scripts I have found. Also in my kernel config there are no modules loaded at all, they are either built in or discarded. I dont know I am going to keep searching /etc/ for some reference to this.

Check modprobe.conf, This might give you some clues as to where to look.
