- [Linear PCM 2 Ch.] audio is set to be output from all output
connectors by default. If you change the audio output settings, audio
will be output only from the connectors that were set.
- If you change the audio output settings, the system will no longer
be able to output audio from multiple output connectors at the same
time. For example, if your system is connected to a TV via an HDMI
cable and to an audio device via a digital optical cable and you switch
to [Digital Out (Optical)] under [Audio Output Settings], audio will no
longer be output from the TV. To output audio from the TV, switch the
setting to [HDMI], or select (Settings) > (Sound Settings) > [Audio Multi-Output] and set the option to [On].
- If you select [Linear PCM 2 Ch. 88.2 kHz] or [Linear PCM 2 Ch.
176.4 kHz] in step 5, sound may be intermittent or may not be emitted
from some audio devices.
- When using an HDMI cable, only [Linear PCM 2 Ch.] audio will be
output from PlayStation®2 and PlayStation® format software. To output
Dolby Digital or DTS audio, you must connect the PS3™ system and the
audio device using a digital optical cable and switch to [Digital Out
(Optical)] under [Audio Output Settings].
- If a device that is not compatible with the HDCP (High-bandwidth
Digital Content Protection) standard is connected to the system using
an HDMI cable, video and/or audio cannot be output from the system.
