One issue I see right away is that you should not be using Ubuntu Studio Controls to adjust the realtime settings. Unless things have changed (perhaps they have), Ubuntu Studio Controls edits /etc/security/limits.conf, which is the wrong file. The file you will want to edit is /etc/security/limits.d/audio.conf. Because you've used Ubuntu Studio Controls, there's a chance that you have settings in both limits.conf and audio.conf, and this can definitely cause issues. Make sure only one of those files has the realtime settings. Hope that helps! -- -Brian David -- Ubuntu-Studio-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
