And it runs SUID root, which could be a security risk. strangely the guy in the vid set rt priorities for qjackctl, ardour and other audio softs he was using as well as the expected jackd. surely only jackd and the sound card IRQ need real time priorities? or am i missing something here? cheers, G.
