- Audio Configuration: Configure the audio routing for the presentation:
- Mixed Audio PCM Only: Multiple PCM audio sources (for example, from a video and audio file playing simultaneously) will be mixed into a single source for audio outputs. Differing volume levels will be normalized, and differing sampling rates (e.g. 44.1 kHz vs. 48 kHz) will be merged into a single rate of 48 kHz. This setting also allows for dynamic adding and removing of audio sources while audio is already playing.
- Mixed Audio PCM / Compressed: The behavior is the same as the Mixed Audio PCM Only setting, but compressed audio is supported as well.
Fixed Audio: Audio sources are mixed only if their sampling rates match, and volume levels will not be normalized. If you attempt to add or remove audio sources while audio is playing, playback will fail.
Note title Note The Mixed Audio options require firmware version 7.0.x or later, while the Fixed Audio option is the legacy behavior.
- Audio: Set the Minimum Volume and Maximum Volume for the audio output (0 – 100).
- HDMI: Set the Minimum Volume and Maximum Volume for the HDMI output (0 – 100).
- SPDIF: Set the Minimum Volume and Maximum Volume for the SPDIF output (0 – 100).
