Problems playing certain wav files

[Ken Marx]

Hi Lucas,

You're a very brave man. Go for it. While you're in there,
see if you can get it to record for maestro-2. I seem to
recall Julian saying it didn't work. He'd be grateful.

Can you clarify one thing? You say:

Does that mean waveplay exits but with now sound? Or is
it as I saw on 5.0 that it hangs.  You have to ctl-C to get the shell
prompt back.

I thought we had different behaviors on 4.8 vs. 5.0.

k.
