Hello, All.

For a few months now, I have been experiencing the following problem
with my Ensoniq Audio PCI card: when playing sounds, it works fine
for the first few times, but at some point the card seems to "hang",
blocking on further write()s.  When this happens, I have to kill the
program that is sending data, but it takes about half a minute for the
program to die.  If I keep trying, by starting and killing the appli-
cation until it succeeds, it will eventually open the device and play
the sound successfully, but the problem eventually happens again.

Below is my machine's configuration.  I am now running -current as of
2001/06/28, but this has been happening for at least five months, always
with -current not older than two months.
