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.
