RELENG_6 and HEAD differ a lot from RELENG_5. RELENG_5 is known to
panic when trying to unload a sound driver. Have a look into
"", maybe you can find a patch which
applies to your FreeBSD version (it should bring your sound system to a
much more improved level). This patch will _not_ be part of 5.5, we
suggest to update to 6.1 or RELENG_6.


            Yes, I've heard of "decaf." What's your point?                       Alexander @
