	I know of no other reason for DRAIN to hang.  DRAIN should return
as soon as the sound card/chip has played all of it's buffered samples.

	It's not a networking issue - the ioctl(DRAIN) is used on your
sound device's fd.

	For kicks (it may not be a problem for your site/usage), why not
comment out the DRAIN ioctl and see what happens.  Perusing the nas
mailing list achive (try google 'sunray site:radscan.com'), it seems at
least one other person had this problem.  But there are a couple of others
where it seems to work ok.

	I am not familiar enough with the solaris sound API and I have no
sunrays, so I do not know if there is another way of achieving the same
effect.
