Broken native sound with 21.2 on Solaris 2.7?

I noticed that native sound no longer works for me on Solaris 2.7. When sounds are played, they go *way* to fast. However, when I use nas, the sounds are played correctly. I tested this also with 21.1.7 compiled on 2.7 and 21.1.4 compiled on 2.5.1. Both of these have the problem. However, an old copy of 20.4 compiled on 2.7 plays native sounds correctly. Also, another bug: (connected-to-nas-p) returns T even though it clearly isn't using nas. I can't believe every Solaris user is using NAS, so I must have done something wrong to break native sounds on Solaris 2.7. Ray
