Using cable ties to bundle audio cables with power 
cords, speaker cables, and so on may degrade the 
audio performance, so don’t do it.
—
An audio cable may be picking up interference. Try 
repositioning your cables.
—
Make sure the source material is Dolby Digital, 
Dolby Digital Plus, and Dolby TrueHD.

When DTS program material ends and the DTS bit-
stream stops, the AV receiver remains in DTS listen-
ing mode and the DTS indicator remains on. This is 
to prevent noise when you use the pause, fast for-
ward, or fast reverse function on your player. If you 
switch your player from DTS to PCM, because the 
AV receiver does not switch formats immediately, 
you may not hear any sound, in which case you 
should stop your player for about three seconds, and 
then resume playback.
—
With some CD and LD players, you won’t be able to 
playback DTS material properly even though your 
player is connected to a digital input on the AV 
receiver. This is usually because the DTS bitstream 
has been processed (e.g., output level, sampling rate, 
or frequency response changed) and the AV receiver 
doesn’t recognize it as a genuine DTS signal. In such 
cases, you may hear noise.
—
When playing DTS program material, using the 
pause, fast forward, or fast reverse function on your 
player may produce a short audible noise. This is not 
a malfunction.
—
Since it takes longer to identify the format of an 
HDMI signal than it does for other digital audio sig-
nals, audio output may not start immediately.
