Hi guys I have had it tough last 2 weeks with dropouts on a project , I opened the last auto save and instant drop out , then every 30 seconds drop out ! so I thought my pc had latency issues - or the Newbury port update from sonar were the cause - or drivers, so I did the biggest optimisation in the history of optimisation , so I have turned off everything and anything and I mean bare bones Windows 10 ,services disables unmarked cores etc etc .device manager disable all drivers I possibly could , all while watching latency mon say about 42us current and up to 1200 peak while a project opened and steady at about 100us constant . Well after everything ( days of searching for the drop out source within the pc and nothing left to turn to ) I decided to open a previous save 1 hour before the latest project ( i am talking about )and found it worked flawlessly no drop outs (  I want to add this is normal and how things normally run NO DROP OUTS ) Anyway I closed it and reopened the latest save again and bang instant drop out and every 30 secs drop out . So I have gone through most of my saves and found about 5 that are exactly the same , I haven't gone all the way back to the 25th of February because there's just to many saves but , I want to add that this is not a problem I have ever encounter with any of all the platinum updates , I noticed a drop out problem the moment I opened a project in Newbury port and have been skipping around what is exactly going on with these drop outs .

So I have now come to learn that during a save of a project with Newbury port , NOT ALL SAVES ONLY SOME , they just drop out continuously , these particular saves get corrupted somehow and drop out instantly and every 30 sec to 1 minute constantly . I have latency mon opened and pc monitor and the latency when each drop out occurs on these corrupt saved projects is steady at 100 us , my buffer is set  at 2048 .

SURELY SOMEONE MUST BE EXPERIENCING THIS AS WELL , IT HAS TAKEN A WHILE DANCING AROUND THE DROP OUTS TO FIGURE THIS OUT , BUT THIS IS A FACT !

THE ONLY THING IS I DON'T KNOW IF ITS THE NEW BURY PORT UPDATE OR A NEW PLUGIN THAT OCCASIONALLY CORRUPTS THE FILE TO CONSTANTLY DROP OUT , BUT WHEN IT DOES THE SAVED PROJECT IS USELESS .(unless i want to drag and drop stuff to a previous working project )

SO I AM ROLLING BACK TODAY TO MANCHESTER FOR ONE REASON ONLY - I WANT TO KNOW IF OVER THE NEXT 2 DAYS OF AUTO SAVES AND MANUAL SAVES , IF ANY OF THEM BECOME CORRUPTED WITH THE DROP OUT BUG .

I WILL KEEP YOU POSTED , PLEASE ANY INFORMATION REGARDING THIS ISSUE IS APPRECIATED ,
 
UPDATE : I HAVE ROLLED BACK TO MANCHESTER > OPENED UP A WORKING SAVED PROJECT>DONE A MANUAL SAVE ADDING MANCHESTER INTO THE SAVE NAME > LATENCY MON IS ALSO RUNNING AT BETWEEN 66 - 175 US WHEN PLAYBACK IS OCCURRING > HIGHEST MEASURED IS -1502 US > NO DROP OUTS AT ALL HAPPENING > LETS SEE WHAT HAPPENS WILL REPORT BACK IN A COUPLE OF DAYS OR EARLIER IF I OPEN NEW SAVED PROJECTS AND THE DROP OUT PROBLEM IS THERE !
 
THANKS

I guess no one else has experienced this, but I did after doing an update that apparently reset the cache settings to the default. When I got the toast notification that a dropout occurred, I clicked on the Help button and went through each step until I tried the cache tip, and that solved the problem.
 
It seems cache settings are very particular to particular computers and setups, there's no "rule" like "bigger is always better" or "use the smallest value possible" or whatever. You just have to play around with the settings.
 
Also check whether the waveform itself has gaps that indicate corruption, otherwise the issue is likely playback-related only.
 
Not guaranteeing any of this will solve your particular issue, but I'd definitely try clicking on Help when the Toast dropout notification pops up and go through the various suggested remedies.
 
 

I would agree this dropout sounds like it's disk-streaming-related. Watch for the disk drive icon flashing red in SONAR Perf Meter just before a dropout, and hover your mouse over it or check Windows Resource Monitor to see how hard the disk is working. When running a high ASIO latency, you may need to increase disk I/O buffers as well or add caching as Craig suggested. The difference between projects could have to do with where different audio files are stored if they aren't all referencing the same audio. Possibly you need to defrag your audio drive.
 
But the DPC latency spikes could also be a problem. Stable is more important than low. 1500us when your average is 100 is a pretty major spike. I wouldn't really expect it to be a problem at 2048 samples, but it could be, and it probably will be at lower buffer settings. You should try to figure out what's causing that.

Hi Brundlefly

It's the saved project file that is corrupted - if I open it with latency mon running there is a drop out every 30 secs constant - however latency mon all green and low - pc resource monitor no spikes nothing ( normally on a drop out these 2 programs show what you are explaing spikes , red bars etc etc , but this is not happening because these particular saved corrupted projects are fu@$ed to the point where they constantly show a drop out that is being caused from when the project saves itself !

If I open another previous project 1 hour earlier and hit play latency mon and pc monitor are exactly the same all green and happy and no drop outs what so ever - it's happening in the saving procedure -

Now I do want to add my thoughts on the possible causes

1) after all the bare bones stripping win 10 back last night I noticed in bios Intel speed step / when I turn this off it cpu is steady at 2.7 , if I switch it on again ( which I have done for now to test the Manchester roll back saving - then the pc goes between 2.7 and 4.2 MHz frequently !

2) I have auto save on every half hour - I use sonitus DX plugins -gate - compressor and I side chain and gate away - a couple of times I have been experimenting with routing to these back and forth I have had audio disappear ! So I'm not sure but I am considering the possibility that these plugins maybe involved ? Can anyone comment on sonitus and Dx versions please .

3 ) this has never happened in any previous update from sonar and I have updated as they come in , my pc had win 10 running with everything and anything and everything and it just worked baby worked -? Soon as I updated newbury port first day drop out - and most days after that the occasional drop out , it got to the point where I was running around stripping my computer back while latency mon Is telling me I don't have to - then I opened the last auto save of my project and I was stuck with constant drop outs all the way through the optimise until I simply opened a previous save and noticed latency was actually right - that previous project worked without a single drop out ( yes with Newbury port playback no problemo , anyways I went back through a lot of saved projects and there are quite a few unusable saved projects all doing the same thing , so more importantly I need to know exactly why this has happened and all I can do is keep all my of settings bare bone and roll back as of yesterday to Manchester and watch over a couple of days if the manual or auto saves are corrupted - if not then I know it's Newburyport - if so then I will switch off speed step and try another couple days and monitor the saves - if that still doesn't work I will switch off all side chaining and gating and if that's not it then I don't know what to do next . Wish me luck because I am confident that I will figure this . You know if it has anything to do with speed step or the ( gating routing which has all been done in Newbury port only - which is why I am curious to see how Manchester handles this ) it still should not corrupt a saved project file to the point where it constantly drops out and yet Windows is not skipping a heartbeat when this happens ?

Thanks

Hi Anderton

I will open one of the corrupted saves and do what you have said with the cache and also the defragment project looks interesting - save as a . Bundle file and sonar automatically defragment It for you - only problem is it won't do it unless I bounce all my audio ! But I will do it cause the project is a drop out - will let you know if it fixes it but Iam am thinking it's something else

Thanks

Hi Anderson I am wondering if your talking about sync and caching ? If so how exactly do you reset !

Thanks

Ok so I opened the latest save project before the Manchester update that constantly drops out > then I bounced all audio files > then I saved it as a bundle file so sonar can defragment > I didn't even need to press playback and there was instantly a drop out > so I hit playback and drop out every 30 sec before bounce and after . So I close that project and opened the bundle file > instant drop out then hit play back and drop out every 30 secs > turn all fx off hit play > drop out every 30 sec .

To the Manchester rollback
I have just open the latest save since rolling back , no drop out yet and I am loop playback while I have breakfast > on silent , but so far so good .

Will keep posted of any updates , will also try anything anyone asks me as well !

Thanks

Ok it's defiantly not Newbury port , the saved projects from Manchester also dropping out - I have completely reinstalled platinum and turned off speed step and had no drop outs , hopefully this is the fix because I am ready for a new pc (:

Maybe I'm totally on wrong tracks, but the use of word "drop out" here somehow puzzles me.
"A drop out every 30 seconds during playback" makes me think about a gap in the audio, not actual drop out, which means the audio engine and playback stops, and it takes many seconds to make it run again.
A gap in the audio every 30 seconds might indicate an unregistered plugin.
If I'm misunderstanding, just ignore.

Hi kalle,

Definitely not a unregistered plugin though I know what you mean when one does have one in a project and it cuts audio out .

I am thinking the first thing I should have done was a full reinstall of sonar( I did reinstall first but I didn't manually delete cakewalk folder under users ) , I have rolled forward to Newbury port , turned of speed step and did a full reinstall , used it all day today and it ran great , so hopefully it does all next week tooooooooooo.
