Hi,

I want to play Linux Audio during kernel bootup as quickly as possible
after board bootup to indicate that board has powered on. I cant wait
until the filesystem is mounted.

I believe this is possible. has anyone tried it? can you provide some
pointers on how to do it?

Where do i need to fill the buffer. is there any specific call i can
make as soon as audio is initialised?


Thanks.
ryan
