Hi David, I don't have time to seriously test audio software now. However, for some time now, I'm already using jack2 build from git. [rocketmouse@archlinux ~]$ grep jack2 /var/log/pacman.log | grep 1.9.10.r | grep upgrade [2016-02-27 18:33] [ALPM] upgraded jack2 (1.9.10-3 -> 1.9.10.r177.g7bdad49-1) [2016-11-23 02:34] [ALPM] upgraded jack2 (1.9.10.r177.g7bdad49-1 -> 1.9.10.r202.gf2ece24-1) [2017-03-02 18:22] [ALPM] upgraded jack2 (1.9.10.r202.gf2ece24-1 -> 1.9.10.r241.ge0281d82-1) [2017-03-28 08:06] [ALPM] upgraded jack2 (1.9.10.r241.ge0281d82-1 -> 1.9.10.r261.g2d1d3235-1) [2017-05-21 18:04] [ALPM] upgraded jack2 (1.9.10.r261.g2d1d3235-1 -> 1.9.10.r262.g31d4ae97-1) [2017-06-14 05:10] [ALPM] upgraded jack2 (1.9.10.r262.g31d4ae97-1 -> 1.9.10.r263.gf3a6b3e4-1) [2017-07-20 16:51] [ALPM] upgraded jack2 (1.9.10.r263.gf3a6b3e4-1 -> 1.9.10.r276.g0f277def-1) [2017-08-07 15:06] [ALPM] upgraded jack2 (1.9.10.r276.g0f277def-1 -> 1.9.10.r279.g9c929bef-1) [2017-08-12 00:44] [ALPM] upgraded jack2 (1.9.10.r279.g9c929bef-1 -> 1.9.10.r283.g288df203-1) [2017-08-18 13:16] [ALPM] upgraded jack2 (1.9.10.r283.g288df203-1 -> 1.9.10.r287.g929009dd-1) [2017-09-16 16:06] [ALPM] upgraded jack2 (1.9.10.r287.g929009dd-1 -> 1.9.10.r293.gc44a220f-1) c44a220 is still the latest commit and f3a6b3e is "1.9.11-RC1 release" [1]. I didn't use all builds to make music, but IIRC all passed at least short usage, so unless you didn't do something very unusual your 1.9.11_RC1-3 [2] should do the job. There was an issue with building jackdbus 288df20 [3], which isn't related to this thread ;).
