The RT rlimits patch (nice-and-rt-prio-rlimits.patch) has been proposed as a solution to allow audio users to run their applications with realtime priorities. While more complicated to configure, it's a much cleaner patch than realtime-lsm and it's likely to get merged soon _if_ enough audio users test it and confirm that it works. To encourage this, I have created a wiki page containing installation instructions, links to prebuilt PAM packages, etc: http://www.steamballoon.com/wiki/Rlimits If this works for you, I am collecting success reports. Please email rlimits-success@xxxxxxxxxxxxxxxx . If you have any problems with it, LAU is probably the best place to ask for help. Unfortunately I don't have large amounts of time to spend helping people with this, so any help requests emailed to me directly may be deleted without a reply. Sorry. Thanks for testing! Jody
