Using the intelX0X0 driver, my onboard nForce sound card performs absolutely perfecto running JACK applications with FC5/CCRMA 2.6.13.rrt--I get xrun-free crystal-clear sound. However, all non-jack apps sound like CRAP (jitters, crackling), xmms complains "check that your soundcard is configured properly", amarok is unstable, VLC plays then immediately kills, xine and mplayer give me nothing . . . Yet my ardour and hydrogen projects sound and perform better than ever! WTF mates? Link
