If you add all users to the audio group, then some users might experience issues, when they don't need RT audio, but they e.g. want to use transparency windows with FLOSS 3D support, when a full preempted (lowlatency) or kernel-rt is installed. Perhaps such a kernel already does cause issues, even if the user isn't in the group audio. However, my user always join this group and the RT vanilla kernels provide doesn't drastically slow down GUI performance when using transparency, but preempted and preempted rt kernels can not be used.
JFTR, keep in mind that for RT nice values are nonsense. The only good values for RT audio are: rtprio 99 memlock unlimited If you guess a nice value would be useful, then you need to set up rtprio < 99, since there is no nice for RT. Likely memlock could become an issue too. And please search LAU, LAD, and I guess especially jack-devel threads for frantic efforts to provide apps that automatically do set up jackd latency settings. IT'S IMPOSSIBLE! Don't write an app that fakes to support something, that cannot be supported. -- ubuntu-studio-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
