Open Sound System

I want to use Baudline, but it doesn't seem to even be compatible with OSS despite it being it's default output driver.

First, it tells me "/dev/audio: no such file or directory".

So I symlink /dev/audio to /dev/dsp (or any other device node).

Then it says "/dev/audio requested fragsize ignored".

Is it trying to use some archaic obsolete OSS API? How can anyone use baudline like this?
