Unable to play 4 channel float32 wav file - Windows 10 64bit R4.5.2

[johnofleek]

Hi
I am working on some new hardware which generates 4 channel float32 wav file. They play ok in Audacity. But they cause Sonic Visualiser to not playback - even if I load a different normally playable wav file Sonic Visualiser won't playback until I close and restart it.

I have attached a sample file which is just 58 seconds of 4 channel ADC noise floor

10.zip

It's possible we've messed up somewhere with our wav generation - any ideas gratefully received
