Trouble with soundloadwave

Hi Guys

I have a little bit trouble with some data stored as an audio wave (quite low frequencies). It is loaded as a text (sic) wave into Igor and I cannot see any data in it.

•soundloadwave /I Fail
  FILE:6K.wav;FORMAT:audio/pcm;CHANNELS:2;BITS:24;SAMPLES:2357460;RATE:6000;
print waveinfo(Fail,0)
  NUMTYPE:0;DUNITS:;XUNITS:;MODIFIED:1;FULLSCALE:0,0,0;MODTIME:3647857807;PATH:;LOCK:0;HGETSTATE:0;SIZEINBYTES:37719760;
print igorversion()
  7.08

Another file sampled at 48kHz also fails to load although the properties returned by soundloadwave are correct. Both files can be played with VLC media player 3.0.7.1. (nothing to hear in it, but the 'spectrum' visualization looks correct)

Any help appreciated

I loaded this file successfully into Igor 7.09.1 on Windows and Igor 7.08 on Mac.

It is a Nightly Build. The release update 7.0.8.1 does have the bug you encountered.

Igor 8 does not have the bug.
