[comp.sys.mac.programmer] System 6.0 and HyperCard's Play command

newton@mtund.ATT.COM (Newton Lee) (06/30/88)

System 6.0 seems to break HyperCard's Play command!  In other words,
the Mac generates a lot of background noise while playing sounds.
Does anyone notice this problem?  Is there a patch to System 6.0?
Thanks.

There was a bug in System 5.0 and asynchronous sound play.  It didn't.
Hypercard 1.0.1 had asynchronous sound play, but that was because Bill
wrote it himself & didn't use the operating system.  I suspect that
you are not using Hypercard 1.2 (let alone 1.2.1), which hasn't given me
any problems with System 6.0 & asynchronous sound play.  While I haven't
tried 1.0.1 (or 1.1, for that matter) with System 6.0, it is a somewhat
reasonable guess that there may be an incompatibility problem with older
HyperCards, later systems, and asynchronous sound play (which all playing
of sounds in Hypercard is -- asynchronous that is).  Someone from Apple
would be in a better position to verify this for certain, but...  Make
sure you are using the latest HyperCard.
