All of the sound input drivers were changed in System 7.5. Unfortunately on a Macintosh Quadra 900 and 950, the "Internal CD" and "External Audio" Sound input options were inadvertently switched. This means that Macintosh Quadra 900 and 950 users need to select the "Internal CD" Sound input option to record audio from external audio sources via the RCA jack. Users who have an internal CD-ROM drive installed need to choose the "External Audio" input option to record audio from their internal CD-ROM drive.
System 7.5 Update 1.0 does not correct the problem. This problem will be corrected in the next update to System 7.5.
