Setting up mediacenter with xbmc and Fedora 15 part 3

I noticed the sound coming from my mediacenter wasn't quite clear.

To have a higher sound quality you need to edit /etc/pulse/daemon.conf.

The resample-method = line can have following values:

src-sinc-best-quality, src-sinc-medium-quality, src-sinc-fastest, speex-float-{10-0}, speex-fixed-{10-0}, ffmpeg, src-zero-order-hold, src-linear, trivial

The first value is the best quality but uses the most cpu time. Please try different values to find a good balance between sound quality and cpu usage.

For me, on a Intel(R) Atom(TM) CPU D525 @ 1.80GHz,   src-sinc-best-quality was a too high setting, but   src-sinc-medium-quality worked fine. By default the setting is speex-float-3.
