There is no audio infrastructure in eCos, no drivers, no
documentation, nothing. Audio is not common in deeply embedded
applications. Applications that do require audio, eg telephones, the
audio support is generally part of the application which contains the
interlectual property. So audio drives don't get contributed.
You will have to do all the work yourself.
