Remedy
• Make sure that Linear PCM Out is set to Down Sample Off (see
Linear PCM Out on page 61).
• As a copy-protection measure, some DVDs do not output 96kHz
audio. In this case, even if set to Down Sample Off, the player
automatically outputs the audio at 48 kHz. This is not a malfunction.
• The player does not output digital audio from the optical/coaxial
jacks at these sampling rates. The digital output is automatically
downsampled.
• Check that Linear PCM Out is set to Down Sample Off
(see Linear PCM Out on page 61).
• Some discs are digital copy protected and do not output high
sampling rate digital audio. In this case the output is automatically
downsampled.
• If this unit is connected to a non-DTS compatible amplifier or
decoder using a digital audio cable, set DTS Out to DTS > PCM. If you
do not do this, noise will be output when you play a DTS disc.
• If this unit is connected to a DTS-compatible amplifier or decoder
using a digital audio cable, check the amplifier settings, and that the
cable is properly connected.
• Make sure that Audio Output Mode is set to 2 Channel if you've
connected to the stereo inputs on your amplifier or TV (see Audio
Output Mode on page 73).
• This player is compatible with multi-session discs, but only plays
sessions that are closed.
• If the message UNPLAYABLE is displayed when you try to play a
disc/track, check the audio file formats (see Compressed audio
compatibility on page 9).
• TruSurround does not work with CD, MP3, DVD-Audio, SACD or
96kHz linear PCM DVD.
• The TruSurround effect is only output through the AUDIO OUT
(2ch) analog audio outputs.
• Make sure that Audio Output Mode is set to 2 Channel (see
Output Mode
on page 73).
• The effectiveness of TruSurround varies with the disc.
• If the audio is switched to [2] when playing a Super VCD that
contains only one stereo soundtrack, there may be no sound at all.
Press AUDIO to change the soundtrack.
