.SH "DESCRIPTION"
.PP
This function sets meta information that can be read using the \fISNDCTL_AUDIOINFO(2oss)\fR ioctl call. It is recommended that the driver calls this function after installing
the audio device.
.PP
This call sets only the bounds to the number of channels supported by the device. It's
possible that the device doesn't support all possible channel configurations between
these limits. For example it may support 2 and 8 channels but not anything between
them. This is OK and the driver developer should not worry about this.
