This may sound like semantics, but having a matrix process active is not the key to minimizing this clicking issue. The key is to set up listening modes so that the same number of speakers are active regardless of the source. So for folks with 7.1 setups it makes sense to use DPL IIx because it will always maintain 7.1 active speakers regardless of whether the source is stereo or 5.1 or 7.1. Other surround processes will work as well.
I follow the "Official Audyssey Thread" religiously myself and you've helped me over there, too.
It was a matter of semantics on my end as to referring to matrixing re: DSX. I know that's not how DSX works, also as per Chris, but since he doesn't explain to us (Rightly so of course as I'm sure the competition watches that thread as closely as we do as every now and then we get a little peek into how Audyssey works
) exactly how it does work, I chose that as the term to use so everyone would understand what I meant so as to get my point across and not confuse. I didn't succeed, lol.
I simply meant that when using DSX you are AUTOMATICALLY "using some technology to derive information from a 5.1 or 7.1 source using fuzzy logic to create additional channels of information/audio" and matrixing was simply easier to type.
My point was that by doing so, since all 7.1/9.1/11.1 "channels" were being used, I was wondering if by using an Audyssey DSX mode, it, by definition, would resolve the relay clicks and was asking if people using a DSX setup also had relay clicking (as long as a DSX mode is engaged of course) or if there is no relay clicking when using DSX.
To be clear, I ALWAYS use all 7.1 speakers (except the rare occasion I listen to 2CH Audio (CD) at which point in time I wouldn't care if there was ONE click going into that mode and the corresponding CD Input and ONE click back out of it into a Sat/Blu-Ray input and =/>7.1 "mode") and if I can assign listening modes to all inputs that will keep the original 5.1 DD signal and create the extra 2 channels for my 7.1 setup or if I happen upon a commercial or other broadcast only encoded in 2CH still using the same surround mode to output audio to all 7.1 channels which will in effect do away with ALL clicking, then sign me up!
I'm simply having trouble verifying if this is the case, can be done, and if others have done this successfully.
Although I have a dedicated theater, I find that 95% of all of my viewing/listening takes place there, which means I will watch my DirecTV programs which are 2CH Stereo, DD 5.1, and watch my Blu-Rays which are DTS-HD MA, TrueHD, etc, plus the trailers/menus/extras which are normally 2CH Stereo, and as long as listening modes can be assigned so I ALWAYS have audio coming out of ALL speakers, and that does away with the clicking, then I'm fine.
I understand there will still be clicking on power on/off, mute, and switching inputs, but does assigning the proper listening modes now totally get rid of ALL OTHER CLICKING? IE: Changing channels, fast forward/rewind, going from a 5.1DD source to a 2CH Stereo commercial, etc, etc?
Again, it's also not just the minor irritation of the "clicking NOISE" that I am worried about as the unit will be in a totally separate room and my dedicated theater is sound proofed (Okay, not perfectly, but 95%) anyway, it's the implication of the "mechanical" nature of said clicking and the fact that it worries me that over time incessant "Clicking" will cause PHYSICAL HARM to the unit. That is my concern and even if I'm told it can happen 1 billion times before failure, I see that simply as a ticking time bomb, especially coming from a flagship unit that has never clicked once on anything except when muting. I'm just anal retentive that way.
I must say, although I can't get confirmation from anyone (Would love to have this conversation copied over to the 80.2 thread or have them invited to read this conversation over here, but don't know how best to go about it, hint hint
) that the clicking can be/has been "resolved" it does sound promising.
Exactly which model are you using, does it have clicking, have you resolved it by assigning these listening modes, and does using Audyssey DSX, (assuming you do) simply by definition, using "fuzzy logic" to derive additional channels (not matrixing) have anything to do with getting rid of (or causing??) any fewer/more relay clicking?

I thought you could indeed get DSX from a 2CH source although Chris said he doesn't recommend it and it is of course "best" to use it with a 5.1/7.1 encoded source.
