The system audio feature on your Adobe Captivate installation can be disabled due to the following reason:
Your operating system is Mac OS, and you do not have SoundFlower installed on it. Soundflower is a free Mac OS extension that allows applications to pass audio to other applications. Soundflower is a prerequisite for recording system audio in Adobe Captivate.
Download Soundflower from this location and install it on your Mac. Restart your machine.
If you already have Soundflower installed, make sure you also have the Soundflowerbed application installed. If you do not have Soundflowerbed application, uninstall your existing Soundflower application, and reinstall a fresh Soundflower application with both the extension and the Soundflowerbed application.
Within resulting Audio Devices display, make sure the Format, Volume, Value, and dB settings look similar to these:
- Format: 44100.0 Hz (2ch-32bit integer)
- Soundflower (2ch) Output: Master Vol=0.845, dB = -3.192 (no mute) | for 1 and 2: Vol = 1, dB = 0, (no mute)
- Soundflower (2ch) Input: for M, 1 and 2: Vol = 1, dB = 40.5 (no mute)
