Problem
Audio is not output
from digital input.
Audio of input
connector is not
output.
Audio is not output.
Audio is output from
digital output
connectors but not
from analog output
connectors.
Audio is output from
analog output
connectors but not
from digital output
connectors.
Compressed audio
(such as Dolby
Digital, DTS) is not
output from the
source device.
Multi-channel audio
is not output.
Audio of only a
specific scene is not
output from digital
input
Cause/Check item/Solution
[14] Is video being output correctly? If not, check [1], [2], [5] and [6].
[15] Is DVI signal output from the source device? You can check
the input signal type in "9.18.9 Input signal status". 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 "9.11.2 Resolutions for PCs"
and "
resolution for AV devices".
9.11.3 Input
[16] 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.
[17] Is the selection of digital audio input and analog audio input
correct?
[18] If the source device has multiple output connectors, check the
audio output settings of the selected output device.
If compressed audio (such as Dolby Digital, DTS, and so on) is
input, analog audio is not output. You can check the input audio
type in "9.18.9 Input signal status".
If the output resolution is set to a value other than "AUTO-A", make
sure that the sink device or AV amplifier supports the selected
output resolution. If a PC output resolution (XGA to 4K) is selected,
some sink devices and AV amplifiers cannot output audio.
If the sampling frequency is set to a value other than "AUTO",
make sure that the sampling frequency is supported by the sink
device or AV amplifier. Some LCD monitors may not output audio
whose sampling frequency is high (88.2 kHz or higher).
Compressed audio input is set to OFF (EDID settings) by factory
default. If using compressed audio, change the EDID setting.
In order to output compressed audio of multi-channel, set the
number of speakers.
Check the audio output settings of the source device.
In order to output multi-channel audio, set the number of speakers.
Is "DOWN MIX" is set for multi-channel audio output?
For multi-channel audio, since channels changes depending on
scenes, audio may not output if audio is not included in the set
channel.
