Yes it helps... even if I had some problems with saa7134-dvb & saa7134 modules (loading that modules, I got complains about versions disagrees).<BR>
<BR>
I suggest to follow that procedure with kernel above => 2.6.25 or waiting for intrepid.<BR>
Here my custom 2.6.25-6-sioux kernel is ok over a hardy release.<BR>
<BR>
Hope this helps too.<BR>

Hi, but I saw this post and thought my solution for compiling the
GadgetLabs wavepro ALSA driver on Ubuntu 8.04 (x86_64) might be of
use. I used a mainline kernel to do it, however.
See <A HREF="https://answers.launchpad.net/ubuntu/+question/35767">https://answers.launchpad.net/ubuntu/+question/35767</A>
Hope this helps!

Original message from Alexey Vinogradov:
Hello.
I've downloaded the sources of v4l-dvb and built them (I have A16D
tuner which is not supported in "main" kernel). However, saa7134-alsa
wasn't built. "make xconfig" also had this module unchecked (and
unavailable to check).
I've found that this is because of "ubuntu" way of building system:
the generic kernel config file doesn't has ALSA subsystem checked.
Actually you have to install two modules: linux-image and
linux-ubuntu-modules. First contains "minimal" kernel with just
essential options - and .config file corresponding to it.
linux-ubuntu-modules contains everything else - including all ALSA
staff, etc.
The comment in media/saa7134/BOM said:
#
# All of the saa7134 sources were copied directly from the 2.6.24 kernel.
#
# The ALSA depedent modules must be built in LUM since ALSA is
# disabled in the kernel. Not all of the saa7134 modules are depedent on
# ALSA, but it just seemed simpler to grab the whole pile.
#
# Note that the compilation of the saa7134 sources is also dependent on
# the kernel headers packages containing some internal header files
# from the drivers/media directories.

So, my problem is that I can't build v4l-dvb saa7134-alsa module
because ALSA is disabled in kernel.
If I enable the alsa in kernel config, it said this during stage 2 of
building modules:

The module after such warning IS compiled - but cause segmentation
fault, and is unusable because of it.
I believe that I need to mess some way the v4l-dvb with sources of
linux-ubuntu-modules - to point some way that the ALSA is exists, and
it is not in the kernel. but in the ubuntu-modules.
Am I right?
How to do it?
