[Audition 2021 v14.1 Windows 10] Some WAV files open as blank?

[XilburQost]

I have several WAV files that I converted from MP4 videos using Switch Sound File Converter. The problem is that when I try to open those WAV files in Audition I just get Audition's blank gray screen, no wave forms, no errors. I would think the problem is the WAV files themselves, however they open fine in other apps including Audacity and REAPER. 

I've tried re-saving (exporting) the WAVs from Audacity, but Audition still treats them as though there's no content; Audition just displays a gray screen. While I'm sure to figure out a workaround, I'm curious: What is it about these WAVs (example attached) that Audition is being intolerant of while other (far less expensive) apps have no issue with?

Thanks.

I just created a 44.1k session and dragged that wav onto a track and it looks and sounds just fine

SuiteSpot--Thank you for checking. On a hunch I changed my MOTU M2 USB Audio Interface driver setting from 48kHz to 44.1kHz and now Audition opens the file just fine. Why this makes a difference I'm not sure, and I haven't experienced this issue with Audition before.

MOTU M2 USB Audio Interface firmware v1.02
MOTU M Series ASIO Driver v4.0.8.4479

If you drag that 44.1k file into a 48k session Audition will make a copy and resample it and it will also look and play fine so this is more a MOTU issue I suspect

Either way it is always best to have your audio interface and Audition session all set to the same sample rate
