normal kernel better than rt kernel on hardy?

[altern]

i have same problem but with feisty. the rt kernel produces more 
glitches and jack/freebob are really unstable. I think it might be 
because i installed Ubuntu Feisty and apt-get the Studio metapackages, 
there was a mail this week about this not being good idea. Maybe you did 
this as well?
