I've completed the new device for libao that just writes raw, headerless,
unformatted audio data to the file of your choice. The driver also supports
writing to stdout by specifying the output file to be "-". This is
the better
way to stream uncompressed audio for now, thereby avoiding the headaches
contained in wav files.
To add the driver:
1) Copy ao_raw.c into ao/src/
2) Apply ao_raw.patch to the ao/ tree. (Note that this patch also updates the
documentation and fixes an error where the esd driver was explained twice in
ao/doc/DRIVERS.
3) Apply vorbis-tools_raw.patch to the vorbis-tools/ tree. This just changes
documentation and the help function for ogg123 to explain the new driver.
4) Rerun autogen.sh in ao/ and recompile.
5) Test with commands like:
ogg123 test.ogg -d raw -o file:test.raw
ogg123 test.ogg -d raw -o file:- | esdcat # Assuming you have esd
