11.4. Audio Issues
If a display on an output using 2-channel stereo audio is switched to an input with an EDID set to surround sound
audio format, audio at the display speakers may be garbled, missing pieces of the audio track, or muted altogether.
This symptom indicates that the display cannot down-convert the audio stream from the source. To x this issue,
the source must be set to output only 2-channel stereo audio.
This may result in less-than-ideal audio quality in zones with surround systems; however with some sources
like cable or satellite boxes, surround sound audio isn’t critical to the end user experience, so these sources can
send stereo audio through the speaker system with no perceived difference. For sources like Blu-ray players or
streaming devices where sound quality is critical, the compromise would be to add a second source of the same
type to the system so that one is set to stereo and one is set to surround sound.
12. SYSTEM LAYOUT CHART
Use this chart to identify the sources and displays attached to the system, and make any notes about each part.
When completing the outputs chart, make sure to indicate whether an HDMI cable or an HDMI extender is
being used to extend signal to the display, and indicate the approximate length of any cables.
