On systems configured for Solaris Trusted Extensions, audio devices are unavailable for allocation at user labels, after upgrading from the Solaris 10 5/08 or earlier releases to the Solaris 10 10/08 or later releases. This bug occurs because the /etc/logindevperm changes are lost during the upgrade. No error message is displayed.
Workaround: After upgrading, manually merge the /etc/logindevperm.old and /etc/logindevperm files to restore Solaris Trusted Extensions configuration changes to logindevperm.
