I might be misunderstanding the question but if your getting a "Failed to enable real time scheduling" warning from some of the examples the following should resolve it: (from the faq): To enable real-time scheduling for non-root users, edit /etc/security/limits.conf and add this line: @usrp - rtprio 50 make sure that your user is a member of group usrp, then logout and back in -- I've found the ubuntu gui (in the version before) a bit dodgy when making the group, the manual way should work of you have the same problem: sudo groupadd usrp sudo useradd -G usrp username -- Worst case you can probably ignore the error unless your getting lots of dropped packets.
