Hi ! I tried the steamballoon patched PAM version with the 2.6.12rc6 kernel. It seems to be working, but I still do not know how to use the RT priority. I tried with jackd, when I launch:: jackd -R -d asla There are no complains, everything seems to be working. But, if I put this line in the /etc/jackdrc file, when I start "jackd", it tells me it can not get realtime capabilities... Does someone know how to grant realtime priority to jackd using the PAM rlimits ? Thanks, Romain.
