Cause/Check item/Solution
If audio is not output, first check the error code in "9.17.8 Sink
device status". (The MSD has multiple output connectors. Find
the error code of the output connector that does not output audio.)
・Error code 1:
Set "9.9.2 Output mute" to "OFF".
・Error code 2:
Ensure that the source device is connected and powered on.
・Error code 3:
Signal is not input. Check [14], [15], [17] and [18].
・Error code 4:
There may be problems in the source device side or HDCP
authentication. Check [14].
・Error code 5:
If the display device or AV amplifier does not support HDCP,
only audio without content protection (such as analog input) is
output; audio is not output when signal with content protection
is input.
Some HDMI/DVI devices check if the connected device is
HDCP compliant and determines whether to output HDCP
signal or not. Since the MSD is HDCP compliant, audio may
not be output if the MSD is connected to a sink device or AV
amplifier that does not support HDCP. In this case, disable
HDCP input from the input device in "9.6.2 Input HDCP
setting".
・Error code 6:
There are problems in the source device.
・Error code 7:
LCD monitors may not output compressed audio, such as
Dolby Digital, DTS, and so on. If playing contents with
compressed audio (such as Blu-ray disc), check the audio
output setting. Audio signal that is output from the source
device can be controlled by setting EDID.
・Error code 8:
Enable the target audio output connector by setting "9.9.7
Audio output connector".
・Error code 9:
Set "9.8.1 Output mode" to a mode other than "DVI MODE". If
the sink device does not support HDMI signal, the MSD outputs
DVI signal automatically. Check which signal type is supported
by the sink device.
・Error code A:
Set "8.2 Switching input channel" to "OFF".
・If any error code is not displayed:
Check [14] to [18]. The source device may not be outputting
audio.
