aplay/arecord start-up error

['Georgina']

Hi

Glad that your requested the version number of the alsa driver as some of
the lines may produce interesting results.  I see that the -d (Duration) was
set at 2 hours, that's a lot of disk space.

Using alsa 09 beta 10 I use these lines:

arecord -d 1800 <filename>.wav

This will produce a 8 bit mono file of 14Mb of half an hour.

arecord -f cd -d 1800 <filename>.wav

Which will record a 16 bit stereo CD quality recording.  Can't remember the
disk space used for this half an hour recording.

A "arecord --help" will tell users what switches are available for their
particular version.  Providing the little indians don't get you, lol.
