Advice on adding snd-aloop to the kernel PKGBUILD

Hi,

As I have an intel HD sound card I have to enable the snd-aloop module so I can record my soundcard's output.

I found this info out from a post here - https://bbs.archlinux.org/viewtopic.php?id=97598 - this led to  http://alsa.opensrc.org/index.php/Jack_ … ack_bridge

It works really well except the fact that I have to re-install the snd-aloop modules after every kernel upgrade I use Jack(mp) and snd-aloop (i rarely ever get any underruns..)

In the arch post 'kazuo' mentioned that I could possibly add the option to the kernel PGKBUILD.

(now I have to compile the alsa-driver from source to add the missing snd-aloop module)

Can anyone advise me where to add the options

./configure --with-cards=hda-intel,loopback,hrtimer --with-card-options=hda-codec-realtek --with-oss=yes --with-sequencer=yes

in the PKGBUILD ?

I compile my own kernel anyway (using PKGBUILD) so it would be easier if I could add the options to it.

Cheers

Re: Advice on adding snd-aloop to the kernel PKGBUILD

on last kernel26-rt-ice upgrade there was a GUI for configuring the Kernel. Can snd-aloop be added there?

Re: Advice on adding snd-aloop to the kernel PKGBUILD

I'm the kernel26-rt-ice maintainer. If there was a gui it was a mistake (leftover stuff in the PKGBUILD from my own compiles). Basically, if you want it compiled into the kernel you may have to apply a patch if one exists (doesn't look like that will be needed but I didn't look too deeply into it).

Next, you need to make menuconfig (or xconfig or gconfig) and then select the correct kernel compile option.

what poped up was a window like this: http://www.shorewall.net/images/kernel-2.6.16-1.png

now, I will try to understand the rest of what you said :-)

Re: Advice on adding snd-aloop to the kernel PKGBUILD

Uncomment the "make menuconfig" line in the PKGCONFIG. Thats part of the kernel source.
EDIT: just realized how old this thread is, sorry.

Re: Advice on adding snd-aloop to the kernel PKGBUILD

In the arch post 'kazuo' mentioned that I could possibly add the option to the kernel PGKBUILD.

After I posted it I greped the kernel sources and looks like that a option for adding snd-aloop is not present.

And now I did a better search and this pop up:

Sounds good.  But, let's merge it into 2.6.37.

So, snd-aloop is not present at the kernel tree, and looks like its gonna be merged at the 2.6.37, because new features can't be merged now at the 2.6.36

@OP As you compile you on kernel, you can backport the work of Jaroslav Kysela and patch your kernel and follow the instructions of ngoonee.

Re: Advice on adding snd-aloop to the kernel PKGBUILD

someone added this to AUR: http://aur.archlinux.org/packages.php?ID=40180
you have to edit the link though for alsa package

I changed source: "ftp://ftp.alsa-project.org/pub/driver/a … 23.tar.bz2"
and md5sum: "4be102f995bd4cc68e6e8178b0d19ec2"
and changed "CD" line to "cd alsa-driver-1.0.23"

EDIT: but it seams it is the wrong version

are there no headers for this kernel?

They're compiled in. AUR does not support split PKGBUILDs yet.

Re: Advice on adding snd-aloop to the kernel PKGBUILD

http://aur.archlinux.org/packages.php?ID=40180

can someone make a small manual how to use this PKGBUILD?
it says:
"Once the modules have been moved to their final destination you must run the command "/sbin/depmod -a 2.6.35-ARCH "
did that and it worked like a charm UNTIL i rebooted and al my alsa-devices where gone. I reinstalled my kernel. What is the correct way?
do I have to move the modules by hand or what does "Once the modules have been moved" mean?

this PKGBUILD es nt working well since the alsa-version always changes.

use this guide: http://alsa.opensrc.org/index.php/Jack_ … ack_bridge
