connectors but not
from analog output
connectors.
Audio is output from

(such as Dolby
Digital, DTS) is not

source device.
Multi-channel audio
is not output.
Cause/Check item/Solution
[12] Is video being output correctly? If not, check [1], [2], [4], and [5].
[13] Are DVI signals output from the source device? You can check the
input signal type in "7.16.7 Input signal status [INPUT STATUS]".
DVI signals may be output depending on EDID settings.
[14] Is audio format being used supported by the connected sink
device or AV amplifier input? LCD monitors, especially, may not
output 88.2 kHz or more sampling frequency of linear PCM and
compressed audio (such as Dolby Digital, DTS, and so on).
Audio signals output from the source device can be controlled by
setting EDID.
[15] Is "7.8.3 Audio input selection [AUDIO INPUT SELECT]" set to
"AUTO"? If not, change the setting to "AUTO" in order to switch the
audio automatically.
[16] If the input device has multiple output connectors, check audio
output settings of the selected input 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
"7.16.7 Input signal status [INPUT STATUS]".
Can the connected display device or AV amplifier output audio with
the selected resolution?
With output resolutions for PCs (VGA to QWXGA), some display
devices and AV amplifiers cannot output audio.
Is the sampling frequency supported by the connected display device
or AV amplifier? Plasma and LCD monitors may not output audio with
a high sampling frequency (88.2 kHz or higher).
If digital input audio is output, check the "SAMPLING FREQUENCY"
of the input audio in "7.16.7 Input signal status [INPUT STATUS]".
"SAMPLING FREQUENCY" output from the input device can be
controlled by setting EDID.
If analog input audio is output, set the "SAMPLING FREQUENCY"
Compressed audio input is controlled (EDID settings) by factory
default. If using compressed audio, change the EDID setting.
In order to output the 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.
