Update: I ran the BD advisor program and everything said "pass." Also, the problem is not with the discs, when I play them on a different player, the audio works fine.
The two BDs that I have had this problem with so far are Get Carter (original 1971 version) and Betty Boop: The Essential Collection Vol. 2.
Installing the patch did not solve the issue.
