alsa-headers & alsa-drivers & 2.6 kernels confusion?

I missed emerging the alsa-firmware, and alsa-headers, so maybe that's why I'm having only partial success.
However, I use 2.6 kernels, with alsa compiled in, so I don't need to emerge alsa-drivers, which is what emerge attempts to do when I do emerge alsa-headers. I definitely don't want to emerge alsa-drivers with 2.6, do I? (I'm on dialup, thus emerge -f, below)
-----------------------------------------------------------------------------
mymachine wrc # emerge -f =media-sound/alsa-headers-1.0.7
Calculating dependencies ...done!
>>> emerge (1 of 1) media-sound/alsa-headers-1.0.7 to /

http://gentoo.osuosl.org/distfiles/dist ... .7.tar.bz2
=> `/usr/portage/distfiles/alsa-driver-1.0.7.tar.bz2'

SNIP
------------------------------------------------------------------------------------------------

But if I do: mymachine wrc # emerge -pv alsa-headers

I get:
These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild N ] media-sound/alsa-headers-1.0.7 0 kB

Total size of downloads: 0 kB

mymachine wrc #
-----------------------------------------------------
Are they really the same file, and as long as alsa is in a 2.6 kernel, I don't
need alsa-headers-1.0.7? What is the correct thinking on this? Or should I
put alsa-drivers in /etc/portage/profiles/package.provided, and do:

emerge alsa-headers?

My latest kernel is:
2.6.10-rc2-mm2-V0.7.30-4 (this is with the real time patch)

Seems to run fine, but I don't think I'm getting full alsa capability here,
with Rosegarden/qsynth/vkeybd. Should I use the CFQ scheduler instead of Anticipatory? I usually run ck kerenls with CFQ, but lately had some
problems.

Any advice is appreciated.

I know this is an old post, but I have the same question. Hopefully someone can answer this.
Someone told me on IRC that since I have the 2.6 kernel, I should just use the alsa module for my via82xx from the kernel, not follow the alsa guide. He said alsa-drivers is only for 2.4 kernel.

you will need the alsa-headers even if you got ALSA in your kernel, since the apps that uses ALSA builds against the headers.

Kernel 2.4.x -

Code: Select all

emerge alsa-headers alsa-tools alsa-utils

kernel 2.6.x -

Code: Select all

emerge alsa-headers alsa-tools alsa-utils

alsa-driver not need because it comes already in kernel, supposing you set it has a module

Just as simple as that !

So, since I am using the 2.6 kernel, do I not need to follow guides such as Wiki Alsa HowTO or Multiple Sound Card HowTO?
My sound is working with the built-in 2.6 kernel drivers; however, I have a couple issues. My sound levels aren't saved (always muted) after a reboot and I can't get my sound working on my PVR878 tv card.

try

Code: Select all

alsamixer

to set you values
then

Code: Select all

alsactl store

to store your values, then

Code: Select all

rc-update add alsasoud boot

and voila next time you reboot you will have your settings from the previous ssessions

Thanks. I'll try that. Do I need to have a /etc/modules.d/alsa file to use /etc/init.d/alsasound?

when you run alsaconf it will create it self

how about alsa-lib with 2.6.x ??

mascanho · Post by **mascanho** » Fri Mar 18, 2005 1:08 pm

what about it ?? , yo do need that one

foosh · Post by **foosh** » Fri Mar 18, 2005 1:28 pm

that's what I thought, but you didn't list it so I was checking whether it was just a mistake or if indeed alsa-lib was no longer necessary

thanks

Yes it is needed, the only one that you can exclude is alsa-driver, but only if you have it on your kernel, otherwise you will need it too

No, alsa-driver is just as valid for 2.6 IF you chose not to use it in the kernel. If you do use built in you -should not_ do both my emergeing as well.
