Hi all

maybe this one is the right configuration of the machine in buildroot

BR2_ARM_OABI=y
BR2_ARCH="arm"
BR2_ENDIAN="LITTLE"
BR2_GCC_TARGET_TUNE="arm9tdmi"
BR2_GCC_TARGET_ARCH="armv4t"
BR2_GCC_TARGET_ABI="apcs-gnu"

I have seen a lot of mailing list and different people report some strange 
problem with alsa. I'm using
a 2.6.29.3 kernel revision

Michael
