[Ubuntu-BR] Jack Audio Server

[Nilson Chagas]

Alguém pode me ajudar, na verdade falar como, eu resolvo o problema de
direito do usuário??? Meu usuário já esta no grupo de audio, e editei o
arquivo limits.conf

How should I configure my Linux 2.6 Operating System? Real-time scheduling

JACK requires real-time scheduling privileges for reliable, dropout-free
operation. The server requests these privileges when running with the -R
option.

Most recent distributions use PAM to manage the permissions of users on a
relatively granular level. If the file /etc/security/limits.conf exists on
your system, it is using PAM. In order to configure PAM such that normal
users can run jackd with realtime privileges make sure the following lines
exist:

@audio   -  rtprio     99
@audio   -  memlock    unlimited

This assumes that the users that are allowed to run jack are members of the
group "audio". If you want to grant this right to one specific user you can
replace @audio with the username of that user. Usually the limits.conf file
contains some instructions on how to use it. *Note that after modifying
limits.conf and/or changing your group membership you must logout and then
login again before any of this will take effect.*
