[relug] ALSA

ho provato a fare l'installazione, ma con scarso successo, in particolare non ci
salto fuori nella parte in cui dovrei editare il modules.conf, per non parlare
del fatto che  devo ancora capire cosa faccia in concreto l'installazione di
alsa-drivers (il grosso della roba va a finire in /usr/src/linux/qualcosa, ma
apparentemente non è cambiato nulla per i sorgenti nè per i moduli...mboh!). Io
lascio qua una copia del README, se per caso qualcuno ha esperienza di
installazioni psichedeliche potrà dire la sua, altrimenti ce la spasseremo un
po' più avanti all'AQ16 con qualcuno più buono (Dirie si starà chiedendo perchè
gli fischino così le orecchie...)

p.s. gli howto li ho trovati incomprensibili, ma devo anche ammettere di averli 
letti di fretta

The ALSA driver replaces the OSS/Free driver. The OSS/Free driver is
present in current Linux kernels (2.2).  Since version 0.4.0, ALSA has
supported only 2.2+ kernels. The 2.0 kernels are no longer supported. You
must compile the kernel with sound support (you do not need to select
any of the other sound modules apart from sound support).

Before installing this driver, it will be helpful to read carefully
the documentation for insmod, modprobe, kmod and for the isapnp
module if you have an ISA PnP soundcard.

Module option name change after 0.9.0rc3
========================================

Note that module option names were changed in 0.9.0rc4. The 'snd_' prefix
was removed. You may use script in utils directory (module-options) to
convert your older /etc/modules.conf to newer one.

Quick install
=============

1) You must have full configured source for the Linux kernel which you
   want to use for the ALSA drivers. Note that ALSA drivers are part
   of the kernel, so there is necessary to resolve all symbol dependencies
   between the used kernel and ALSA driver code. Partly installed kernels
   (for example from distributor makers) can be unuseable for this action.
2) You must turn on sound support (soundcore module).
3) Run './configure' script.
   If you have ISA Plug & Play soundcard, use --with-isapnp=yes switch.
   If you want sequencer support, use --with-sequencer=yes switch.
   If you do not want OSS/Free emulation, use --with-oss=no switch.
   If you want turn on debug mode use --with-debug=full switch.
   If you want debug soundcard detection try --with-debug=detect switch.
   If you have kernel source code in another directory than /usr/src/linux,
   use --with-kernel=<kernel_directory>.
   Example: ./configure --with-isapnp=yes --with-debug=full
4) Run 'make install'.
5) Run the './snddevices' script to create new sound devices in /dev directory.
   Skip this step, if you have a kernel with the DEVFS support.
6) Edit your /etc/modules.conf (see the kmod support section below).
7) Run 'modprobe snd-xxxx' where xxxx is the name of your card.
