Onkyo TX-SR705 firmware update (DTS bomb fix)
English

I am experiencing audio pops/bombs when listening to DTS HD MA tracks from Blu Rays playing on my PS3.  Most recently I heard it on Master and Commander.  It just happened once during the movie, but when it happened, I rewound a few seconds to see if it would happen again, and it did, right in the same spot.  I know I've heard it a couple of times before, but I couldn't tell you which movies, or even that they were definitely DTS HD MA tracks.  I'm guessing they were though.  It seems this "DTS bomb" thing is a know issue that there is a firmware fix for.  However, I can't seem to find any official route for downloading the firmware fix from the Onkyo website.  There is no firmware update listed for the TX-SR705.

The update method I've read about involves downloading a WAV file, burning it to a CD, and playing that CD through the optical input on the receiver.  Sounds a bit convoluted!  I don't even have an optical cable, so it would mean buying one of those.

Has anybody done this?  How do I get the download?  Does the fix work?  How much danger is there of these bombs damaging my B&W 685 theatre package speakers?

Thanks for any help!

Re: Onkyo TX-SR705 firmware update (DTS bomb fix)

Depending on your current version of firmware, the 705 may have to go back to Onkyo (Genserve) for a hardware mod.


If you do a search for Genserve, you should find the threads you require (although most refer to the 875 & 905).

Could you hear any damage on your speaker then, when listening too them now? There is a possibility of them causing damage from what i have read.


Onkyo like you say did do firmware updates and as far as i know they did work.  How you get the firmware updates i don't know.

Some Onkyos required a hardware upgrade before they could be firmware upgraded. GenServe should be able to tell you what's required if you quote the serial number.

Thanks for the info guys.  I'm in Ireland (Dublin), so I don't think GenServe will be any good to me.  Also, the home theatre specialist where I bought the receiver has since closed down - so I can't go back to them.

What about the Onkyo support line?  Has anybody had any dealings with them?  I sent an email to <customercare@eu.onkyo.com> a couple of days ago, but have yet to hear anything.

Hi jphealy


Yes, the firmware update does work as I have updated a few onkyo's over the last 2 years including my own, plus there is no hardware modification needed for this firmware update as its only updating the DSP.


I am sure I have still got the WAV file with the instructions on how to update, if you still want to do it your self as it's easy to do then let me know on this thread and I will find it out for you.


All the best.


Mike.

Re: Onkyo TX-SR705 firmware update (DTS bomb fix)

Phew! Thought I'd tempted fate by responding to this post: just got back after two weeks away, powered the Onkyo 875 back on after having it switched off completely all that time and got an error message and - umm, nothing.

Fortunately managed to restore operation courtesy of a factory reset, so at least I can watch TV. Did rough distances and levels by ear/memory; proper set-up will have to wait until the weekend.

Worth remembering that today was only the first working day back so in reality, they've only had today to look into any other queries that have come their way over the Christmas period.

Hi jphealy


You are in luck! I found the DSP update and uploaded it for you to mediafire, so just click here and download and unzip, instructions are in there too in PDF format.


Any problems, I'm here to help.


All the best.

Thank you SOOO much Mike!  You are very kind to do that.  I will hopefully be able to do the fix tonight when I get home from work - although I need to get my hands on an optical cable first!  Don't have one at home.  I've uploaded the files to my Dropbox anyway for the moment, for safe keeping.  I'll post back with how I get on.

Do you recall, does the update return the receiver to factory settings?  Will I have to set it up again from scratch, or just run Audyssey or something?

Anyway, thanks again very much indeed.

No problem at all, glad I could help.


Yes, it does reset all setting to factory default and you will need to re-run the set up process again.


What others are talking about is the main firmware which needs to use the com port at the back of the Amp and updates all the rest of the AMP, but you need to be above 1.04 to update to the latest one and need a computer or laptop with a com port on, only recommend this if you know what you doing really, and it takes around 15-20 mins to update. If you feel you what to do this update, I do have the main firmware and I can upload them if you wish but to be honest! If you are happy how your amp is running and its only the DTS bomb you have the problem with then I would only do DSP update and you will have no problems then.


Let me know how you get on.


All the best.


Mike.

Re: Onkyo TX-SR705 firmware update (DTS bomb fix)
Big Chris:What is the latest version? I'm running version 1.07.


Latest version is 1.08, but need to update the HDMI board as well.


The only change in this version is for the AMP to remember setting as some of the AMPS when turned off forget there settings as it did happen to me once only, and seems its happened to Andrew as well, but there is a way around that by running the set-up and after its complete save it to its back-up memory, to do this,


From the front panel - Push and hold "Set-up", then Push "Enter".
The unit will display "Set-up Store?", still holding "Set-up" push "Enter" again and the unit will display "Set-up Storing", then it will display "Complete" and thus the procedure is complete.


Then if you ever need to recall these settings for what ever reason (some one messing with your settings or your AMP as forgot them) to do this,


From the front panel - Push and hold "Set-up", then Push "Return".
The unit will display "Set-up Recall?", still holding "Set-up" push "Return" again and the unit will display "Set-up Recalling", then it will display "Complete" and thus the procedure is complete.


I found this out a couple of years ago on another forum.


To be honest I tried firmware 1.08, but it wipes the HDMI firmware, then you need to update the HDMI firmware separately and I this takes ages, then I found after everything was complete the AMP takes ages to handshake with other equipment, so I went back to 1.07 and I just used the above procedure just in case my 875 forgets its settings.


All the best.


Mike.
