The drive should be the same - it is mostly userspace and the generic kernel interface that changes. All you should need to do is compile alsalib.

forgive me; I am new to linux,

Do I need to build the kernal with audio support and reload it or can I compile alsalib seperatly, if so can you point me in the right direction- if I use make in the src directory i get nothing but errors.

TIA Anthony

You need to rebuild userspace -- the best thing to do is go to the top level, and :

- check to make sure you are using fdpic: -

rgetz@imhotep:~/blackfin/trunk/uClinux-dist> grep -i fdpic ./config/.config

CONFIG_FMT_USE_FDPIC_ELF=y

- if not switch. then make clean

- make sure alsa is turned on in userspace:
