I'm on a system that works fine from an audio perspective and there are 
some files that sound fine if I redirect them to /dev/dsp. The one you 
chose is *not* one of them.

Here's one that does work:

532 > file  /usr/games/chromium/data/wav/boom.wav
/usr/games/chromium/data/wav/boom.wav: RIFF (little-endian) data, WAVE 
audio, Microsoft PCM, 8 bit, mono 11025 Hz
533 > 

And here's one that doesn't:

531 > file  /usr/share/sounds/KDE_Startup.wav
/usr/share/sounds/KDE_Startup.wav: RIFF (little-endian) data, WAVE audio, 
Microsoft PCM, 16 bit, mono 22050 Hz

The proper test should be to use the play program to handle whatever 
conversions are needed.

Also, I'm not an expert on this subject, but my understanding is that .au 
files are always the lowest common denominator file type and that 
/dev/audio is always the lowest common denominator audio device. (If I'm 
wrong, someone please correct^H^H^H^H^H^H^Heducate me.
