Thanks Chris for the reply. I tried from http://jackaudio.org/linux_rt_config, however, I still get the "Opertaion not permitted error". Anyhow, I just noticed, that on x86 (on which I am able to use "Import Audio" feature, even after audacity startup), "ps -aux | grep jackd" DOES NOT show any running instance of jackd. So, I really am at a loss; as what to look into, and what not. Regards, Ajay On Sat, Mar 31, 2012 at 8:20 PM, Chris Caudle <chris@xxxxxxxxxxxxxxx> wrote: > Don't run jackd as root..
