The issue I have is that close_audio_out() isn't working as you'd
expect: for some reason, the 'audio_out_' member pointer is null
This was because all of the I/O operations were ignoring the archetype
for the device.  So, this is likely an old bug.

So, good news/bad news.  Good news: I checked in a fix which causes the missing
1.5 seconds to be played.  Bad news: The process now hangs in waveOutClose()
in fhandler_dev_dsp::Audio_out::stop.  There seem to be a few threads hanging
around waiting for something so obviously something isn't cleaning up right
in the audio code.
Nope.  Wrong theory.  I know what's causing this but I don't yet know how to
fix it.
This should all be fixed in the upcoming snapshot.
Thank you for looking at this. I've tried the 32-bit snapshot dated
'2014-03-17', but whenever I pipe a wav file to /dev/dsp I get a
segmentation fault. The error is produced immediately, and no sound is
heard. I've tried wav files both longer and shorter than 1.5s.
What does "pipe a wav file" mean?  I was testing this by doing:

cp h.wav /dev/dsp

I was testing with

    cat ding.wav > /dev/dsp

This gives a segmentation fault with the latest (2014-03-18) snapshot; no sound is heard However, if I repeat your test:

    cp ding.wav /dev/dsp

Then that works and the ding dings. Which confuses me greatly - I've been using *nix for nearly 20 years, and I honestly would have said that the two lines above were synonymous - they're obviously not!

Dave.
