ALSA startup
 

After

apt-get install alsa aumix && alsaconf

alsa starts up automatically at startup but does not load snd-intel8x0 and its other dependent modules

insmod snd-intel8x0 doesnt work either-->WHY?

modprobe snd-intel8x0 does however-->WHY? but insmod doesnt work?


Adding snd-intel8x0 to /etc/modules loads the correct modules on startup, but why do I have to do this when my other rollings of the distro on the same machine in different partitions but exact same setup do not require this modification (snd-intel8x0 is not present in /etc/modules).

Is there something I forgot from those last installations?
Additionally alsaconf is a lil different...doesnt let me pick the cards from a long list but lists the one (s) on my machine and doesn't do any extra configuring.

Is there a command I forgot, tried update-modules and the editor to add/remove modules from /etc/modules?

Thanx!

modprobe loads a module and all it's dependent ones,
insmod doesn't.. just the module.

Also install the alsa-utils package, gives the alsactl programme.

Modules are added to /etc/modutils/aliases, then run update-modules.
Alsactl adds new aliases to describe the sound system major and minor numbers and which module relates, eg if you have OSS compatability or not.
These are listed as..
[snip]
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore

##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.

will get back to ya
 

very informative and i can remember something about alsactl; however, it was starfire was fixed w/ a pretty built ghost backup and dropped into its container...bf24 woody reinitization...voila!

however, am making another installation on raven that includes latest of 2.4 kernels as point of comparison...nvidia drivers...and will need to remember when i add alsa

thanx! will get back with ya on the fat n skinny
