Audio output (Cont’d)
Audio is not output.
・
Error code 9:
Set “
to a mode other than “DVI MODE”.
If the sink device does not support HDMI signal,
theIMP outputs DVI signal automatically.
Check which signal type is supported by the sink device.
・
Error code A:
Set “
7.1.1 Selecting input channels
to the value other than
“OFF”.
・
If any error code is not displayed:
Check [6] to [9]. The source device may not be outputting
audio.
―
[6] Is video being output correctly? If not, check [1] to [5].
―
[7] Is DVI signal output from the source device? You can check
the input signal type in
DVI signal may be output depending on EDID settings.
If a source device that does not support 4K is connected to the
input connector to which 4K EDID is set, DVI signal may be
output. Change the setting of “
” to a
value other than 4K.
[8] Is the input audio format supported by the connected sink
device or AV amplifier input?
LCD monitors, especially, may not output 88.2 kHz or higher
sampling frequency of linear PCM and compressed audio
(such as Dolby Digital, DTS, and so on). Audio signal output
from the source device can be controlled by setting EDID.
[9] Check the audio output setting of the source device.
―
Audio is output from
HDMI output
connectors, but audio
is not output from
analog output
connector.
If compressed audio (Dolby Digital, and DTS) is input, analog
audio is not output. The analog audio output supports only
2 channel LPCM. You can check the input audio type in
Audio is output from

is not output from
HDMI output
connectors.
Does the connected sink device support the input resolution?
If a PC resolution (VGA to 4K) is input, sink device may not output
audio.
Does the connected sink device support the sampling frequency?
Some LC monitors do not support high sampling frequencies
(88.2 kHz or higher). Audio signal that is output from the source
device can be controlled by EDID setting.
