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.
