aplay/arecord start-up error

[Charles Hallenbeck]

Hi Igor,

The script I sent Greg, and which he resent, is not too
meaningful without a detailed commentary, and it is specific to
version 0.9.0beta11 of the alsa drivers. So if you just copy that
script it may or may not work for you.

In general you need to use a bunch of options with arecord in
addition to naming the file you want to create. You need to
specify the sampling rate you want to use, the sample size, the
file type, how many channels to create, and the duration of the
recording you want to make. How you do all those things will vary
somewhat depending on your version of alsa. The documentation is
pretty skimpy, but it is all there in the man page if you have
the patience to tease it out.

If you can tell us the alsa version you are using and show us the
command line you tried to use perhaps we can get more specific.
