overload indicators not functioning

[recording date]

When recording the overload indicators on the level meters don't function anymore how overload the incoming signal may be. I tried resetting Audition (CS6) and I even reinstalled the software but to no avail. It is just like if a hidden hard limiter is at work. Even with ridiculous high input levels the signal seems not to go over 0 db. Can anyone explain me that (and give me a tip how to resolve this?

What audio interface and drivers are you using on what operating system?

I'm working in an Windows 7 environment. The signal comes from an external source (or from an internal hard disk) , is injected in a Allen & Heath Qu24 mixer and then it goes through my Roland Quad Capture device. No limiting or compression whatsoever is applied. Neither have the settings on my computer been modified (save the fact that I augmented the size of the buffer in Edius 8 to the maximum value of 8 Gb but I suppose that this cannot affect Audition!). Many thanks in advance.

What audio drivers are you using for the Roland? Do you have the latest ones provided by Roland? Apparently the Roland has something called 'Autosens' which might have some bearing on the fact that audio levels never get up to 0dBFS. If they worked previously then something must have changed but not, I suspect, anything to do with Audition, unless you have changed the Device Class settings in the Audio Hardware prefs page. The level and Peak sensors on Audition's input side are sent by the audio interface drivers AFAIAA. Do the Peak indicators work OK if you turn up the level when playing back pre-recorded audio files?

Well, the Peak (overload) indicators certainly are, but I'm not so sure about the levels - I think Audition determines those from the incoming stream. However you look at it, this is going to be an external problem though, as Audition is remarkably good at dealing with what it's been sent.

I do have the latest driver for the Roland. The autosensfunction has indeed an effect on the recorded soundlevel but it is not acting as some kind of "hard limiter" and it allows peak level signals to come trough. I think that I'Il have to connect the roland to another computer (equipped with Audition) to be sure that the problem is not generated by my computerconfiguration.
