Unable to attach mixer to device AndroidOut: No such file or directory

[kuldeep ghan]

I am trying to get audio working with android kernel. I am able to play wav
files with alsa_aplay but when I try to open Output or Input stream using
libadio Its failing.

Can anyone help me with this? what could be wrong?

Where are AndroidOut and AndroidIn created? what is the possible reason for
failure above?
