Or should I just save some money for a real amp Hi, someone posted a link to a patch for the DSP code in FreeBSD a few weeks earlier: ftp://rusunix.org/pub/FreeBSD/patches/dsp.1.67-1.70.patch It should work well with the 5.2.1-RELEASE branch. In my case, it made the gaps between selecting tracks in XMMS go away. Cheers, Tobias ps: Anyways, I guess something like ALSA would be the best for the job. Or Apple's CoreAudio ;-)
