| Summary | 0004946: Unable to start jack server in realtime mode on Fedora | ||||
| Description | When starting the JACK server via Ardour's audio engine dialog in realtime mode on Fedora it always fails. This is because it tries to start the server with a realtime priority of 60. The maximum priority available to someone in the jackuser group is 20(without editing the pam security config files). As there is no way to change this priority via the audio engine dialog perhaps it makes sense to let the server set a default priority by not passing the -P arg when starting the jack server. | ||||

I've attached a patch that fixes the issue(at least on Fedora) by setting the default realtime priority to 20. I'm unsure if this will be sufficient for other distros etc. |

Thanks, I just removed the setting altogether, so Ardour shouldn't request a particular RT priority in SVN 12924. |
