Hi there,

I want to compile some new alsa drivers for a MID device running ubuntu, because actual sound drivers on the device make some cracking noise all the time. The device (o2 Joggler) comes with an intel Poulsbo chipset (Sigmatel 9202). The original software on the device (a small linux with no big functionality) runs the alsa driver 1.0.15.

That's the version, we have existig patches for. See those links: (Patches 0010 and 0014)

http://software.intel.com/en-us/articles/patches-for-moblin-kernel-on-menlow /

http://www.soulinfo.com/~hugang/tmp/ubuntu-hardy%2Btuxonice/debian/binary-cu stom.d/lpia/patchset/

It looks like these patches aren't still concluded in the newest alsa-drivers, therefore I'd like to use and compile version 1.0.15.

But this seems not working with newer kernels.

Here are the error messages I'm getting:

make -C /root/Desktop/linux-2.6.32.10 SUBDIRS=/root/Downloads/alsa-driver-1.0.15 CPP="gcc -E" CC="gcc" modules make[1]: Betrete Verzeichnis '/root/Desktop/linux-2.6.32.10' scripts/Makefile.build:49: *** CFLAGS was changed in "/root/Downloads/alsa-driver-1.0.15/acore/Makefile". Fix it to use EXTRA_CFLAGS. Schluss. make[2]: *** [/root/Downloads/alsa-driver-1.0.15/acore] Fehler 2 make[1]: *** [_module_/root/Downloads/alsa-driver-1.0.15] Fehler 2 make[1]: Verlasse Verzeichnis '/root/Desktop/linux-2.6.32.10' make: *** [compile] Fehler 2

and still 1.0.16 which has corrected the EXTRA_CFLAGS, gives me this list of errors:

--------------------------

Is there any possibitliy to compile version 1.0.15 with a new kernel?

Or the second way - is it difficult to apply those patches on a newer alsa driver?

I tried to apply them "manually" on a new alsa driver, but without success.

I thank you for any help on this!

Best, Christian
