 * TODO:
 *  o   Test the driver on cards other than a single
 *      Prometheus Aria 16.
 *  o   Look into where aria_prometheus_kludge() belongs.
 *  o   Add some DMA code.  It accomplishes its goal by
 *      direct IO at the moment.
 *  o   Different programs should be able to open the device
 *      with O_RDONLY and O_WRONLY at the same time.  But I
 *      do not see support for this in /sys/dev/audio.c, so
 *	I cannot effectively code it.
 *  o   We should nicely deal with the cards that can do mu-law
 *      and A-law output.
 *  o   Rework the mixer interface.
 *       o   Deal with the lvls better.  We need to do better mapping
 *           between logarithmic scales and the one byte that
 *           we are passed.
 *       o   Deal better with cards that have no mixer.
