* 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.
