repeatable crash with 7.1

Post by dr » Thu Apr 28, 2011 11:44 am

tried opening some .wav files from DVD using the "right click > open with"


win7 - running as admin- UAC off

immediate crash:

unable to stop the application - reboot was only way to fix.


I assume this was some kind of write-permission, unable to write the peak files to the DVD ? copied to file to the desktop and it opened (right click - open with) with a similar crash - and says "unable to create peak file" - although a peak file is created. When you quit the program you get a crash on exit

when you reopen wavelab it remembers you tried to open the file and reloads it fine - complete with peak file.

seems to me like some kind of problem creating gpk files - and it seems to have different behaviour if you open file from a writeprotected medium (DVD) and if you use the rightclick>openwith rather than ctrl-o

behaviour seems to change if you open files a few times - I assume wavelab is caching something

help !

When a media is protected, WaveLab writes the peak file elsewhere.
I just tried it, and it works. So ignore why there is a problem in your case.
For performance reasons, it's never a good idea to access audio from optical media. You should copy the file to your HD to solve the problem.

As I mentioned I copied the file to the desktop and also gave problems

I'd suggest it's a similar issue to:

So the problem is certainly in the file header. The file header has a problem that WaveLab can't handle properly (?). If you can make this file available somewhere, I can have a look.

it's possible that it's something in the header - but that shouldn't force a system crash ?

I'll PM regarding sending the .wav

When something is bad in the header, WaveLab normally recovers from it. But there are maybe cases that were not seen before and that WaveLab does not handle properly.

the behaviours does seem inconsistent - and seems to be related to the peak files (IMO !)

when copied to the desktop the files do open some of the time ? and as I mentioned I get "unable to create peak file" error occasionally.

I'll try to get a more reliable repro.

PG can open file correctly.

Just to confirm my repro:

fresh install win7 pro - 64bit - running as admin - no UAC - random nvidia card with latest drivers

file downloaded to desktop - without gpk file. Wavelab is closed

right click to open with wavelab

http://i62.photobucket.com/albums/h101/ ... 1_open.jpg

I get peak file error "Cannot create peak file" - and no peak file is created

http://s62.photobucket.com/albums/h101/ ... 2_peak.jpg

if I then open the file from the file browser in the top left window

http://s62.photobucket.com/albums/h101/ ... veform.jpg

all looks fine and peak file is created ok

close the file and all still looks ok

http://s62.photobucket.com/albums/h101/ ... closed.jpg

when I then quit wavelab

http://s62.photobucket.com/albums/h101/ ... _error.jpg

As the peak file has been created the next time I open the file it works without error.

problem seems to lie in peak file creation ?

Sometimes if I use the rightclick to open a wav without a gpk file I get a crash on opening (QtGui4.dll) and I'm left with this greyed out crashed screen

http://i62.photobucket.com/albums/h101/ ... /crash.jpg

you can see it's started to build the waveform and there is a 0byte .gpk file created

only option here is to reboot

Still can't reproduce. Does the same happen with another file? Does the same if you put the file *not* on your Desktop?

yes, happens on another drive/folder
happens with another random file created by cubase - although welcome.wav doesn't generate the error. . . but also doesn't generate a gpk - I assume it's too short ?

As per other thread, doesn't happen if gpk exists

Behaviour is different if you use the open wavelab using right-click on .wav > open with. File browser in already open wavelab tends to be more successful.

Sometimes you WL starting to generate the waveform and it draws about the first 10 seconds very quickly then gives the "Cannot create peak file" error - possibly when it starts to write the gpk with the disk.

All disks are all NTFS - permissions all look fine. Wavelab 6 works fine - never had any problems with it, in fact I've bought/used every version since v1.5 and never had any issues with previous versions.

This could be a disk problem. Try to run the Windows disk error utility on your drive.

Yes, welcome.wav is too short. Try with long files.

As I said, other longer files give same errors. Not a disk write problem. Occurs on 3 disks, all of them show no chkdisk errors. No filesystem/bad sector probs.

Peak files are created near the audio files, or in a separate folder (Audio File Workspace preferences). If they are created in a different folder (are they?), is this path really valid? Check Options > Edit folders.

Peak files are created in same folder as the audio file. As you can see it does write the file correctly if you open the file by using the file browser.

I will have to think about this...
If you drag from Explorer and drop to WaveLab, does it work or not?

a drag and drop from explorer has the same result as right-click > open with.

In summary:

When there is no gpk file - using explorer or open-with gives either a crash or a "cannot create peak file" error and crash on exit. Using file browser in wavelab creates the gpk file fine and seems to work ok BUT give crash on exit.

when there is a gpk file - all works fine however you open the file.

All that is very strange, because internally, these methods are similar. The only difference I see, is that with "Open with" and "Drag and drop", there is more interaction with Windows, *before* the files are open. Therefore there must be something in your Windows settings, or an installed utility, that is making WaveLab in a bad state, when this happen. I have no other clue.

I've very few applications installed on this pc - no virus scanner, no background utilities - just the core audio stuff

Hard to know what is specific to my pc - although it does seem others are having 'similar' problems.....and it's possible you wouldn't notice if you only opened files within wavelab...you'd just get a crash on exit, which I notice some people seem to be getting.

As the error seems to be QT gui related it could be graphics driver related ? Does wavelab write the gpk file then display or is this done concurrently. Nvidia put out new drivers every week or so ! I could try an update although the currently installed drivers are only about a month old. Do you have the older nokia QT dlls that I could try ?

updated graphics card driver - no change

tried running in winxp sp2/3 compatibility mode - no change

tried running as administrator (even though I'm logged on as admnistrator) - no change

rolled back to 7.01 - no change

reinstalled 7.1 - no change

There's definately something strange going on :?

Hi,

Just for a test try with WL 7.00 build 506
and see if this is the same as with 7.01 and 7.10

This is the only report I ever had about this particular problem.
Personally I open 90% of my files by Drag and drop.
Peak file building happens in a "background thread", which is synchronized with the "UI thread". But this has almost nothing to do with Qt. What I see in your crash dump, is that the problem is related to memory allocation. But I see no other details. This is no helper.

Can this be related to hardware memory 16 GB
dual or triple configuration doesn't match on MoBo ?

thanks for the suggestion - just tried that - still the same issue.

http://www.steinberg.net/forum/viewtopi ... =47&t=7287
look similar with mrk (does he mean gpk ?)
and john lance problem at the bottom of this thread is the same
http://www.cubase.net/phpbb2/viewtopic.php?t=140406


this is one of the new sandybridge chipset (the fixed b3 version !) - hyperthreading turned on hence 8-core. 16gig memory. Problem with the way the new sandybridge handles memory / multithreading ? I haven't seen any issues in any other software, although wavelab is the only 32bit application on there (there are a few legacy 32bit plugs). Been running 64bit cubase 6 without a hitch for the last month - not one crash.

Passes the window7 memory test fine and the crash is totally repeatable so I don't believe it's faulty ram - and if there were any other issues I thought I'd have seen them elsewhere ?


Either way I've still a couple of WL6 licences which at the moment I still prefer, so if there's no more experimenting I can try, I might leave WL7 and try it on the next update.

PS - I'm fairly convinced there's a bug there when creating gpk but can't quite put my finger on it - I just wonder what is different about my pc config to other working ones.

dual channel mobo - dual channel memory

the sandybridge boards have a (working!) turbo mode so by default it's running at 1600mhz and the system (and memory) is very understressed. Error occurs if turbo mode on/off.

doesn't "feel" like a hardware problem to me - could be wrong of course :)
