I downloaded audio.tar.gz, patched the diff into cc.c and cc.h, recompiled
the kernel and in audio directory, make load,
the system complained:
dev_audio.c: in function " audio_write", "custom" undefined,
dev_audio.c line 301, 355: deferencing pointer to incomplete type.
Error code 1

What is wrong? Can anybody help?
Thanks in advance.
