Does the internet interfere with Qjackctl?

view story

http://askubuntu.com – I got the Qjackctl issue I was having fixed, then a little less than an an hour later, got this message in Zynaddsubfx: I think it may have something to do with the fact that right before this happened I was on the internet. One of the things I did to set up Qjackctl was to put this code in the Terminal. cd /etc/security sudo nano limits.conf And then at the bottom of the page that comes up I put in this code. rtprio -99 memlock unlimited nice -10 Should I avoid using the internet when using Qjackctl and other audio programs? Thank you in advance for any help tha (HowTos)
