Follow-UpChris Caudle Re: [Jack-Devel] Portaudio "queries" on ARM 
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
