hi toleda thanks for the quick reply!
i'm glad my sound wasn't totally broken!
i deleted the s/l/e/HDAEnabler889.kext
i attached my new ioreg.
i still see the same assertion as before. it happens when sound has been inactive for a while ... them it triggers the following: the speakers pop and these errors appear in the log:
