Hi Aaron
Sorry for not getting back.

I did reinstall the firmware and same thing happened. I went back to the old software before 1.1.2

I just upgraded to 1.2 and 2 nights in a row I have had an audio drop out.
I changed the buffer to 5ms as I was on 2ms and i still get a drop out.

It happened once when I was tapping the hot cue button.
And again when I wasn't even touching the SX

The second issue has been sorted thank you!

But I need to get to the bottom of this drop out!

Ok so buffer all the way down to it's lowest setting.
Still have the odd dropout and it happens a few hours into a set so totally random, even happened without touching the controller.
Nothing has changed on the laptop, the whole laptop has been optimised to the guide on the Serato site plus other recommended settings by Audio guys across the world.
The Laptop has never once had an audio dropout before 1.1.2

Just to go over things~
Everything worked 100% before upgarding to 1.1.2

Reinstalling 1.1.1 and I'm back to perfection but without the .2 upgrades like Autoplay and the later version which offers the 3 FX per channel :-(

DDJ SX Firmware is 1.0.5 which has been reinstalled twice, just in case.
I will upgrade this to 1.0.7 which has just been released.

USB connections~ Just the DDJ SX
HDD~ standard HDD with the operating system, CD Rom drive changed to a caddy which holds the music HDD which is a 750gb with only 200gb being used. This has worked flawlessly for over a year with VDJ and SDJ.
Defragmented frequently.

Gilbz: You may want to consider a RAM upgrade if you have a large library.

You went back to 1.1.2 and now everything is working normally? No audio drop outs?

No went back to 1.1.1 and all is fine, what have they done to 1.2 to make me need more ram? All was good since November until 1.2

I'm not too sure what may have changed between versions but maybe the newer version requires more resources from your computer now than before. USB buffer underruns and audio dropouts are usually caused from the software choking on itself due to lack of resources (computer horsepower).

I'm just giving suggestions. Please don't take my suggestion for a ram upgrade as a "for sure" fix :-)

Appreciate any suggestions mate!

Hi Aaron

Thanks for the reply.

I have yet to look at the task manager to see if there is anything else running. I'll do that shortly.

The buffer is to the right so it's on 20ms.

I've upgraded to the latest SX firmware and have had a bash and all is ok so far.

Something else that has happened twice now is that all of a sudden I get a high pitch squeel through the speakers. Both times I have been in my office playing and not at a gig luckily.

The first time it happened I pulled the USB lead out of the laptop and it went.

Today I waited for the tune to stop, reloaded another but it was still there. press numerous buttons in case it was an FX stuck on, but nothing would tunr it off.

With no music playing the master output in SDJ was showing 4-5 green bars continuosly lit. So it appears the laptop or something is creating the high pitch squeel.

shutting down SDJ the squeel goes away, restarting SDJ and it stays away.

Any ideas?!! Sorry to add more issues. I have looked on the forums and it's not ground loop issues or HDD noise.

Hi Aaron

At the time on both occasions I wasn't using any effects, just beat mixing.
when it happened tonight I was just about to quit for the day and the track was coming to it's last 2 minutes. A high pitch squeel was heard so I stopped the track and brought the chanel volume down. You could still hear it. Only reducing the master volume on the SX reduced it

I'm going to replace the usb cable tomorrow

Back to 1.1.1

Had enough of these drop outs. Had around 4 tonight in a 5 hr set.
Sounds totally unprofessional and puts me on edge.
As soon as I did my set tonight I uninstalled 1.2 and gone back to what I was using when I knew everything was good.

Brand new USB cable, different USB port.
At least I didn't get the loud squeel!

:-(

Going to do a lot more testing this week.......

Hi Aaron
there was nothing else running in processes.
the only thing running was Serato which cpu usage was 5 to 28%.

Only thing I can do is either ram upgrade or clean install of windows & Serato

Cheers mate
appreciate your help. I'll keep you updated. :-)

Oh, and I have a powered hub somewhere so I'll try it!

Ok update

Clean install, optimised, running 1.2 and still got drop outs.
Task manager nothing is running but SDJ, latency goes to the highest of 673.

Next step is powered hub.
Sadly I can only get this to dropout when I'm gigging! When I'm in the office it's fine!
Bit like when you take your car to a garage and the fault disappears :-(

If the powered hub don't work I will either have to go back to 1.1.1 and lose the great updates or buy a new laptop with a higher spec.

I don't think I will upgrade the RAM, yeah it's cheaper (but still £110.00) but I'd prefer to get something a lot more powerful.

One thing I did consider~ Could it be the platters playing up?
I remember I was playing deck 1 and it dropped out a while ago, Sunday night it was deck 2 dropping out.
It's like someone or something touches the platter for a split second pausing the music.
Still think it's software issues though

Hi Aaron
Thanks for the recommendations. I'm going to try them all

I wouldn't say it could be down to vibrations, I'm mobile rather than club so the bass isn't massive and if it was then I would have had this issue when I had my big big rig out before the upgrades. As that rig really pounded hard.

On another note/ issue on saturday night I suddenly had one of the decks go into reverse!
I had to hold the censor button down to make it play forward!

Is my SX breaking up?!!

The only other laptop I have is running windows 8, so not an option :-\

Cool, I'll ask my 12yr old if hr doesn't mind dad nicking his 'toy'! Haha!

I'm up to trying anything, been using pc/laptops for 8 years with hardly a glitch til now!

Due to personal circumstance I still to try Windows 8
For the past 2 gigs I went back to 1.1.1 and no drop outs at all, so I'm happy for the time being.

Once my 'circumstances' change I'll have more time to experiment.
Is it possible to keep this open?

Thanks again Aaron for the suggestions

Cheers mate ;-)

Weirdly having installed 1.2.1 I've had no drop outs.

But then I'm only doing 2hr gigs at the moment

That sounds promising :) Let me know how it goes as you play more.

Cheers

Yeah, will do, cheers Aaron

i also get random usb dropouts. I was thinking of updating the firmware but after reading this, I'll wait until I hear back on an actual resolution to Gibz' issue.
