Hi all.

Greetings from a VERY hot Australia.

I sent this to acorn.misc but I'm not sure if it went so in the spirit of
belt and braces, I'm trying here as well.

For some time I've been using OHP (Tony Still& Photodesk) very
successfully to produce presentations which include visual and audio..

To associate an audio file with a still in the Scripts window you just
drop it on top.
OHP accepts WAV files which I am using. This has always worked flawlessly
in the past. I've usually done it on my FAT RISC OS 5 machine but I'm
away at the moment and using

       Virtual Acorn Adjust 4.39 Windows 10 Acer netbook

I think I've done it on this machine as well but can't remember.

This time I get an error message 

      Sound file unusable: Couldn't auto-detect sample format.

The sound files seem not to be corrupted as they play perfectly with
Andre Timmermans'  Digital CD.

In Reporter I see a list of filetypes set for Digital CD one of which is

FB1 WaveForm

In my MimeMap I see the line

audio/L16		WaveForm	fb1	.wav .l16 .AIFF

Is .116  an alternative RISC OS filetype?

If I look at SetType for my audio file it gives Wave. I have seen
previous ones which give WaveForm.

Any idea what might be going on?

Meanwhile, I'll do a bit of experimenting changing file type to FB1.

I used Rick Hudson's SoundCon to convert one WAV files to Armadeus format
and OHP recognised that but I wonder if the conversion degraded the sound
quality a bit. Hard to tell on this tinny netbook speaker. 

Now all the files show the Armadeus icon, not the WAV icon even though
I've only converted one.

Any enlightenment gratefully received.
