>Description:
/usr/ports/audio/mp3blaster looks to be an interesting lite mp3
player without the bulk of Gnome or KDE. So it is. But then I 
noticed my brand spanking new Athlon 800 MHz machine was at 100% 
CPU utilization playing thru mp3blaster. About 72.0% system, 26.0% 
user, remainer is other.

Sound card is a cheap OEM Soundblaster 128 (ES1371).

Not believing this was reasonable, installed the mpg123 port. CPU
utilization with mpg123 is essentially nil at 0.49%
>How-To-Repeat:
Install and run the mp3blaster port. Watch the system with "systat -v"
and/or "top -I".
>Fix:
My guess is the application busy loops rather than block on I/O.
