+In the above configuration examples, the pcm.dsp0 definition is used to wrap calls do /dev/dsp0. You can also wrap usage of /dev/dsp1, /dev/dsp2, etc. by defining pcm.dsp1, pcm.dsp2, etc..

+In the current form, aoss is not able to wrap OSS applications that make use of libc's FILE* infrastructure (fopen() and friends) for their communication with the OSS sound driver. This is because libc uses internal versions of open() and friends which cannot be intercepted by LD_PRELOAD'ing a shared library..
