The DSP only carries out the instructions. DTS wrote those instructions.

Are you sure? Funny that not ALL avr's were affected. And Onkyo fixed their problem with a software patch.

Yes I'm sure, Onkyo and Yamaha were the first out of the gate, and the first affected. DTS rewrote their TI DSP codec and Onkyo issued it as a DSP firmware update.

DTS also promised to look into their encoding method to minimize the spikes but it appears that certain titles still have the problem. Hence the joke among the HT community that "DTS" stands for Destroy The Speakers.

Looks to me like DTS could care less about this. They have yet to even respond once with even an "it's not us-it's somebody else" to 5 emails I've sent in the last 2 weeks. If you have ever experienced this first hand, you would be leery of even playing a movie with a DTS MA soundtrack again for fear this might occur.

I've recently experienced these loud pops through my Denon 3808 AVR with the movies Tangled and Burlesque. Never heard them before with numerous DTS-MA audio tracks running through my setup.

Pops aren't repeatable. I could play the films all the way through and not hear a thing, but heard them on a subsequent play. Strange.

At least there's some comfort that this thread has been revived. Good to know I'm not alone.

The original, decoder firmware flaw leading to the original "bomb" had the characteristic that the explosions were repeatable at the same time code when decoded on the same hardware (although the decoder in different hardware might not have the problem on that disc, even though it had the problem on some other disc).

If your explosions are not-repeatable, then that suggests a different flaw.

I bought a br player a while ago and took it back. This thread makes me leery about even thinking about buying another br player or getting a new receiver. I'm sure Dolby is enjoying this. I used to love it when DVDs had DTS soundtracks. Oh yeah, has anyone experienced the "bomb" or "pop" on a Dolby True HD soundtrack?

Why? A large majority of BD content is using DTS-HD-MA, and up to now this was forgotten concern as it was a issue with earlier audio decoders against Yamaha, Integra, and Onkyo AVR's , since fixed with new FW and new hardware. Just because you see a couple of people discussing this problem doesn't make it the norm.

This doesn't occur on Dolby True HD tracks BTW.

Actually it's the opposite: a few BD players needed firmware updates to because they would have Dolby TrueHD dropouts: the sound would cut out completely for a brief second here and there on some titles.

Hi Guys,

I have an Onkyo ts xr707 and a Panasonic BD60

Is there a certain firmware version that this issue is effecting? Or is it across the board across all firmware versions?

I have a couple of the Blu-rays on the first post (Master & commander and Room 1408) that I have not watched yet, thank goodness!

I will check my firmware version when I get home (Support guy said you hold "display" and press "Standy" to show firmware version)

The POP sound is it while your watching a movie or only when you fast forward the Bluray disc?

Yes, I just bought an 805 and hoped someone would answer.
Someone could possibly come back with answers.

Onkyo firmware updates do not fix any of the DTS HD Master issues. They just fixed bugs in the programming of the receiver itself... You need to get the DSP updates to fix the DTS HD Master bomb issue. Note that there was two updates, one was about fives years ago and the other was about two years ago.

You need the most recent updates to fix the "bomb" issue. You should be able to get them from Onkyo. Also note that the updates are flashed thru the optical port on the receiver. You will need a CD player with optical outputs to flash the receiver. Most DVD and nearly all of the Blu-Ray players are NOT able to flash the DSPs. I had to use a dedicated CD player to flash my receiver. No other DVD player would work.

BTW, the DTS HD Master bomb is only apparent upon playing a disc...

Thank you for the information.
I don't know what is going on with mine then. I notice the popping or static noise with DTS HD Master and TrueHD only at fast forward and once when I turned on the player without a disc.

Dolby True HD never had an issue with sound AFAIK... The bomb would appear when playing back certain movies and a REALLY loud pop would appear from the speakers. So loud, it would blow out your tweeters if the volume is at reference levels. It occurs when the receivers decoder gets a signal from the disc that it did not recognize. Star Wars and Eat, Pray, Love were the two discs I know that had the issue... Someone told me that How to Train Your Dragon also exhibited the same issue but I could not verify it.

What you are describing does not sound like the same issue... It appears that possibly the muting circuit is not working right. Try and find out the firmware update on your receiver. if it is old, a new update may fix it...

The problem is I cannot update the firmware because I have the original one installed and there is no way to do it other than having an Onkyo service center do it and there is none near me.

How To Train Your Dragon is Dolby TrueHD, so it having the "DTS bomb" would be impossible.

Maybe they meant Eragon or Dragonheart...
