     33  * TODO:
     34  *  o   Test the driver on cards other than a single
     35  *      Prometheus Aria 16.
     36  *  o   Look into where aria_prometheus_kludge() belongs.
     37  *  o   Add some dma code.  It accomplishes its goal by
     38  *      direct IO at the moment.
     39  *  o   Different programs should be able to open the device
     40  *      with O_RDONLY and O_WRONLY at the same time.  But I
     41  *      do not see support for this in /sys/dev/audio.c, so
     42  *	I cannot effectively code it.
     43  *  o   We should nicely deal with the cards that can do mulaw
     44  *      and alaw output.
     45  *  o   Rework the mixer interface.
     46  *       o   Deal with the lvls better.  We need to do better mapping
     47  *           between logarithmic scales and the one byte that
     48  *           we are passed.
     49  *       o   Deal better with cards that have no mixer.
