Hi everybody,

I had some trouble to find out which patch is meant by

"use-menuconfig-objects-ii-sound.patch"

Just could not identify it.

So I reverted the following patches of 2.6.22-rc2-mm1:

--- linux-2.6.22-rc2/sound/Kconfig	2007-05-19 02:24:08.000000000 -0700
+++ devel/sound/Kconfig	2007-05-22 21:03:24.000000000 -0700

AND:

--- linux-2.6.22-rc2/sound/drivers/Kconfig	2007-04-25 23:42:23.000000000 -0700
+++ devel/sound/drivers/Kconfig	2007-05-22 21:03:24.000000000 -0700

Result:

The Alsa architecture is performing excellently!

Cheers

Uwe

So at least one of them should be ripeed out for being buggy.
