cdparanoia plugin fixes

Hi All,

I've had following problems with cdparanoia plugin v0.1 (and cdparanoia 
itself) - it somehow manages to induce 30-100% CPU load when playing 
CDDA real-time. This happens even with -Z key meaning "paranoia is off". 
I believe it's connected with latest 2.4.x Atapi driver DMA support (I 
have 2.4.20-8) and the fact that cdparanoia tries to defeat read-ahead 
cache by reading big chunks from drive (I have 512K buffer in my Artec 
16x DVD-ROM). This causes occasional playback breakup, looks lile also 
causes missed timer interrupts. In short - quite nasty.

But CDDA playback is a nice thing to have. Nobody wants to use cheapo 
DACs of you drive to listen high-fidelity uncompressed music :) Also 
audio effects is a nice thing to have.

Solution for this problem that I came up with is adding plugin mode that 
bypasses paranoia and uses cdda I/F directly. Anyway there's not much 
use for "paranoia" when playing real-time. I works beautifully! One can 
get an updated cdparanoia plugin v0.2 SRPM or pre-compiled RPM at

Hope it helps :)
