Why does the alsa guide tell you to build your in kernal sound as modules? I think that it is better to have my sound card built into the kernel rather than inserting it at boot. The only reason I see for modules is if you use the alsa-driver package.

I have also thought: why not built the sound into the kernel instead of having modules - I'll load them anyway.
But I have had problems when I did this - this was a long time ago.
Since then I always use modules.
If it is any help - the guide mentions this:
Quote:
Please note that for ease of use, all examples show ALSA built as modules. It is advisable to follow the same as it then allows the use of alsaconf which is a boon when you want to configure your card.

and for me the valid reason is: this approach works, while the "build it in" approach causes problems.

You can pass parameters to modules while loading.

The reason is because it makes it easier to detect the card. The alsa-driver package has nothing to do with anything. The only reason you would use that if you didn't want to use the kernel's drivers at all.

So, three ways to install:

1) In kernel, compiled in
2) In kernel, as modules
3) nothing in kernel, external modules (alsa-driver package).

#2 is the recommended use. #3 is unsupported.
