I have an Oppo BDP-93 and I use a Dennon 4311 for a pre-amp. 9.2 PLZ set up.

So far, every BR disk we have watched had some sort of audio issue. Either complete momentary drop outs, clicks, or other oddities.

I just don't have the patience to surf AVS for the cause. Any quick suggestions that do not include buying a new BR player and AVR/Pre amp? I'm waiting for true 4K before I upgrade anything, and that will be a complete room overhaul.

I have an OPPO BDP-103D and have the occasional audio dropout where I have to hit the chapter back button to fix it. Or, if I pause it for a several minutes, it takes it a while to get started again in jerky motions. You would think as much as these blu-ray players cost (mine was $600), that it would have fewer and not more problems.

I think it's just an OPPO issue. Good quality audio and video, when it works.

Over the years, I have had a series of Oppo players up to and including my current BDP105 and never experienced such issues with any of them. I would suggest, however, from my own experience, rather than surfing the net for possible solutions to any problems, contact Oppo directly for advice. They are often pretty quick to respond.

Try setting Secondary Audio to OFF in the OPPO if it is ON.

My 3 year old inexpensive Sony BDR has performed flawlessly over its life so far. It is 1/6 the cost of the OPPO & it is doubtful that anyone could hear or see much, if any, difference in the sound or picture. Plays SACDs beautifully as well.

When it dies, it will go to the electronics recycler & I'll get another one for probably even a lower price...

I would check for a firmware update.

The Oppo firmware is up to date. The AVR, not so much. I reckon that would be the first place to start.

I use the Oppo players because they play well my Lumagen XS. I sent the XS the raw video output.

I did a quick search at AVS, despite my earlier declaration that I wouldn't. It's hard to interpret comments, but it would appear that there is a hardware issue with the older units and Atmos, bitstream. If the comments I skimmed through are correct, I either need to upgrade to a unit with the "5" designation, or send my AVR PCM.

I'll just give Oppo a call.

I am confused. What does Atmos have to do with this? The 4311 can not do Atmos. Why would you even choose playing the Atmos soundtrack?

Cause Atmos is the coded sound track on some of the newer BR disks. There is no other choice, unless you speak a different language than English. Something to do with new anti-copy write crap the studios are using now.

So far, two disks that come to mind with these drop outs are Expendables 3 and John Wick.

Response from Oppo on this......

"This is a limitation of the player's hardware due to changes in the encoding standard for Dolby Digital TrueHD soundtracks that use Seamless Branching. This is not something that we will be able to fix through a future firmware release."

I doubt they will ever stop pirating. But it is good for the hardware makers. Soon we will have new 4k bluray drives for ripping , Oppo et el will make another BDP-XXX and we will be drug into another upgrade cycle against our will. My BDP-93 is like new and cost 500 and now they want me to do it all over again. I pay the penalty for a bunch of neerdowells stealing a lousy friggin movie. T

Technology is great, it just lasted too long.
