109 * The first part of this file contains the new FreeBSD sound ioctl
110 * interface. Tries to minimize the number of different ioctls, and
111 * to be reasonably general.
113 * 970821: some of the new calls have not been implemented yet.
117 * the following three calls extend the generic file descriptor
118 * interface. AIONWRITE is the dual of FIONREAD, i.e. returns the max
119 * number of bytes for a write operation to be non-blocking.
121 * AIOGSIZE/AIOSSIZE are used to change the behaviour of the device,
122 * from a character device (default) to a block device. In block mode,
123 * (not to be confused with blocking mode) the main difference for the
124 * application is that select() will return only when a complete
125 * block can be read/written to the device, whereas in character mode
126 * select will return true when one byte can be exchanged. For audio
127 * devices, character mode makes select almost useless since one byte
128 * will always be ready by the next sample time (which is often only a
129 * handful of microseconds away).
130 * Use a size of 0 or 1 to return to character mode.

141 * The following constants define supported audio formats. The
142 * encoding follows voxware conventions, i.e. 1 bit for each supported
143 * format. We extend it by using bit 31 (RO) to indicate full-duplex
144 * capability, and bit 29 (RO) to indicate that the card supports/
145 * needs different formats on capture & playback channels.
146 * Bit 29 (RW) is used to indicate/ask stereo.
148 * The number of bits required to store the sample is:
149 * o 4 bits for the IDA ADPCM format,
150 * o 8 bits for 8-bit formats, mu-law and A-law,
151 * o 16 bits for the 16-bit formats, and
