Question Can't configure ALSA

Hi there,

I am in the mid-way of having ALSA in place on my (B)LFS 6.1. I installed ALSA-lib, ALSA-plugins, ALSA-utils. When I tried to configure the utils with alsaconf it says something like
modinfo : could not find module snd
which : dialog not found
which : whiptail not found
Error, dialog or whiptail not found.
"which" seems to be in place, but I can't understand what dialog and whiptail are (neither LFS nor BLFS indexes contain anything alike). BTW, lspci lists my AC97 on-board sound "card"
... Multimedia audio controller: VIA VT82C686A (rev 10)...
no unknown things listed, so LFS found my soundcard.
I tried to recompile the kernel without any modules - no changes.

In order to get any further, I need structured answers to the following questions (if I'm mixing up things, please correct me):
1. The kernel. In order to get my soundcard (on-board, VIA686A chip based, AC97) working, shall I (re)build the kernel:
a) with sound support enabled or modularized?
b) with my type of soundcard enabled or modularized (or maybe disabled as the ALSA website suggests)?
c) other things enabled or modularized (and which namely)?
2. The ALSA package.
a) How can I find out that my operating system recognized (found) the soundcard, and its just ALSA that can't interact with it? In this case, it just has to be configured properly, right?
b) How is it configured?

If anyone encountered the same or similar problems, and solved them successfully, or just knows the answer to a particular question I posed please let me know.

Dialog is use by the alsaconf script to generate dialog boxes.
Get it from here:
But, I dont recommend using the alsaconf script.

My sound card worked automaticly. I guess because I compiled it into the kernel, and I only have the sound drivers that I need. All I had to do then was change the mixer settings with alsamixer.

If you wan't to figure out if your kernel sees your card, and the driver is working with it do:
look under "ALSA device list:" you should see something simular to:
  • #0: Ensoniq AudioPCI ENS1370 at 0xc800, irq 5
Let me know if this helps.

Thank you for your help, shotokan,

I solved this problem by completely re-building the core LFS system. This looks like I made some stupid mistake while building the system for the first time.
