[gentoo-user] alsa in-kernel vs. alsa-lib

[Pupino]

Hi all,
i was used to intall alsa-lib and co. and use tools like alsamixer to
manage the audio on my gentoo; now i've tryied to switch to the
in-kernel way.
I've built the relevant part into the kernel, no module, but now i'm stuck.
If i try to emerge alsa-utils (wich has alsamixer) it pulls in also
alsa-lib, alsa-header, etc...
is this the correct behaviour? i tought i'll get rid of those
packages(-header, -lib) switching to the in-kernel drivers.

alsa-lib and alsa-headers are unrelated to the kernel modules.
alsa-lib and alsa-headers are userspace.
If you ditch alsa-lib and go full kernel:
Will you have sound? Maybe.
Will alsa-using apps be able to use it? Absolutely not. They need alsa-lib.

From my experience i would recommend to use alsa-in-kernel + alsa-libs + 
alsa-headers + alsa-utils + alsa-tools

This combination works perfect on my 3 gentoo machines

void shameless_plug()
{
     One of the reasons I love Gentoo is
     because it allowed me to recompile all
     apps without ALSA support and use OSS
     (version 4) instead which for me worked
     much, much better than ALSA.
}

ok, all of you said alsa in-kernel + alsa-lib + alsa-header is working
perfectly.
Yes, it's working for me too on my other gentoo box.

But i read this after building alsa-lib:
* Please try in-kernel ALSA drivers instead of the alsa-drivers ebuild.
* If alsa-drivers works for you where a recent kernel does not, we want
* to know about this. Our e-mail address is alsa-bugs@gentoo.org
* However, if you notice no sound output or instability, please try to
* upgrade your kernel to a newer version first.

and this makes me think i should get rid of those packages as it say "instead".
Is this wrong? do we still need alsa-lib and co.?

You should _not_ install alsa-drivers if you want to use in-kernel drivers. 
You can and should install alsa-lib etc.

It says "instead of the alsa-drivers ebuild". you use either the
in-kernel drivers or alsa-drivers, whichever you choose, you still need
alsa-lib.

g++     plug.cpp   -o plug
plug.cpp: In function 'void shameless_plug()':
plug.cpp:4: error: 'One' was not declared in this scope
plug.cpp:4: error: expected `;' before 'of'

how about some printf's (or cout's for you noobs)

As if printf's aren't for noobs.  The Real Programmer puts the string 
length in EDX, the string in ECX, puts 1 in ECX to signify stdout, 4 in 
EAX to select the sys_write system call, and does an int 0x80.

FYI that's alsa-lib not alsa-libs :)  might confuse someone reading later.
