[linux-audio-user] jackd acts weird

[eun.sung]

hi

ok, i finally managed to sound out with real-time capabilities by 
downgrading to a 2.6.15 kernel with realtime-lsm package built out

i use a hda-intel card
and jackd (svn 0.102.20) runs perfectly in playback only but as i try to 
use a duplex mode it crashes

did anyone met this problem too?

thanks
greetings
