Note: This module is obsolete, since the hardware to which it interfaces is obsolete. For audio on the Indigo or 4D/35, see built-in module al above.
This module provides rudimentary access to the audio I/O device /dev/audio on the Silicon Graphics Personal IRIS 4D/25; see audio(7). It supports the following operations:
These operations support asynchronous audio I/O:
The following operations do not affect the audio device but are implemented in C for efficiency:
