I tried this solution for my troubles with Jack and freebob on my f8 /
PlanetCCRMA, but it does not solve them. I don't want and don't have much
time  to re-install f7. Have you find any solution for this issue ? Do you
think it is possible that an older kernel (2.6.22) works ?
Thank you

All the best,


Mysth-R
