+.SH "DESCRIPTION"
+.PP
+Applications using audio can ask what formats the device supports using various
+ioctl calls. The driver must provide this information. Usually it sets the format mask
+when installing the device using \fIossddk_install_audiodev(9ossddk)\fR. However it
+may be necessary to change this information later if a change in device's mode of
+operation also changes the formats it currently supports. Another situation when
+this function should be called is when the device supports different formats
+for recording and playback.
