AudioTuneUp 2.0

AudioTuneUp 2.0 is a set of extensions that fix certain audio-related problems encountered on PCI-based Macs.

Areas of Troubleshooting
The problems as shown below can be fixed using this update:


 * Power Macintosh G3 and Power Macintosh 4400: Attempts to record from the external microphone using QuickTime fails
 * PowerBook 2400c, PowerBook 3400c and PowerBook G3: When running off a battery, sound sometimes does not play
 * Power Macintosh 5400, Power Macintosh 5500, Twentieth Anniversary Macintosh, PowerBook 2400c, PowerBook 3400c and PowerBook G3: Feedback (i.e. the loud "shrieking noise") occurs when attempting to use some application programmes to record audio from the internal microphone

The extension set is only to be installed on Macs running Mac OS 8.1 (except for a Power Macintosh G3, even under Mac OS 8.0) that are suffering from these problem.

Contents of the Installation Package
The installation package takes form as a tome and includes two drivers and two shared libraries, totalling 64 KB in size.
