[linux-audio-user] Audio system flaky on all but JACKd apps!

[Link Swanson]

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?
