lately, i've noticed some audio drop-off while watching blurays...specially during intense action sequence, the audio volume would simply drop-off intermittently or for a few seconds before returning to it's original volume..is there something wrong with the BD disc or is this setup/hardware/cable problem?
My setup consist of a samsung 40"led TV, lg bd530 player, creative ddts-100 decoder, creative inspire 7.1 and connection are as follows:
LG BD530 > LED TV ( HDMI cable but HDMI audio is set to OFF )
LG BD530 > DDTS-100 Decoder ( COAX cable connection only )
By "drop-off," I assume you mean the sound totally cuts out intermittently, and that it's not merely a lowering of the volume.
A total cut-off in the sound is called an audio dropout.
Analog audio via RCA is more reliable than digital audio via coax. With analog audio, the signal is transmitted without problems even if the connection is slightly loose or dirty. But with digital audio, the slightest loose connection will produce audio dropouts.
So if you're having audio droputs on digital audio, the cause is probably a bad connection.
I experienced audio dropouts with my coax connection before HDMI became fashionable. I replaced the coax cable with an Acoustic Research Master Series, the one that can be tightened by the user by screwing the connection counter-clockwise. Problem solved.
You twist the ribbed part of the gray
plastic to tighten the connection.Make sure your coax connection is tight enough. Try pulling them out and pushing them back in while rotating them as you push and pull to remove dirt/fungus if any. Or try a contact cleaner spray. If that doesn't work, try another coax cable.
