If you have an audio device in your config file this is
IMPORTANT, otherwise you can stop reading.

The high level (MI) audio driver now attaches to the low level driver
in the normal way (instead of the weird magic that happened before).
This means that an extra line is needed in the config file
to make audio work.  An example

sb0     at isa? port 0x220 irq 7 drq 1  # SoundBlaster
audio*  at sb0                          # NEW

The line marked NEW is the new one; without it the high level
driver will not attach and /dev/audio & co will simply not work.

The config files in the distribution have been updated so there
are plenty of examples to look at (not that it is a difficult
line to add).

This change should appear with the next sup scan.
