Problem
Audio is not output from
digital input.
Audio from IN 1 to IN 5
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.
[14] Is video being output correctly? If not, check [1], [2], [5], and [6].
[15] Are DVI signals output from the source device? You can check the
input signal type in "8.18.7 Input signal status". DVI signals may be
output depending on EDID settings.
[16] 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.
[17] Is "8.8.3 Input selection" set to "AUTO"? If not, change the setting
to "AUTO" in order to switch the audio automatically.
[18] 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 "8.18.7
Input signal 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 "8.18.7 Input signal 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.
