Re: Error in user manual.

There's also more to this which I frankly don't fully understand.

For example, I have a portable machine with a Pentium III which plays
multiple wav files just fine in Windows, but not in my Linux
installation. At least not until I installed Jack:

http://jackit.sourceforge.net/

This is software to allow multiple, simoultaneous sound. There's at
least one other app like Jack that I've come across, but I don't recall
what/where.
