Change Details

Even though the OSS manual [1] advises against using AFMT_FLOAT, there are applications that expect the sound driver to support it, and might not work properly without it. This patch adds AFMT_FLOAT in sys/soundcard.h and implements AFMT_FLOAT <-> AFMT_S32_LE conversion functions. As a result, applications can write/read floats to/from sound(4), but internally, because sound(4) works with integers, we convert AFMT_FLOAT to AFMT_S32_LE before doing any processing.

Even though the OSS manual [1] advises against using AFMT_FLOAT, there are applications that expect the sound driver to support it, and might not work properly without it. This patch adds AFMT_F32_LE|BE (as well as AFMT_FLOAT for OSS compatibility) in sys/soundcard.h and implements AFMT_F32_LE|BE <-> AFMT_S32_LE|BE conversion functions. As a result, applications can write/read floats to/from sound(4), but internally, because sound(4) works with integers, we convert floating point samples to integer ones, before doing any processing.
