Hi to all,

I finally found the solution to the problem I posted nearly three years ago:

The reason for this and for the memory mapping crash is unrelated to glav or 
lavplay. It is due to mixer setting. As I stated before, I'm new (5 yeears now) to 
Linux, a slow learner, and have not too much time to play and experiment.

THE ROOT CAUSE OF THE PROBLEM WAS	

The recorded sound was over-modulated. This is why glav and lavplay either 
crashed or complained about memory mapping, and this is why the -U option 
did noT help. The short snippets of sound were evidences of the too loud 
recording.

Apparently mplayer is tolerant of this and therefore I though my recording was 
OK.
