Audio driver (jackdmp) error on OS X

Post by kiwiplant » Sun Feb 17, 2008 1:29 am

Hi,

I am trying to run linuxsampler for the first time ever and am using
OS X 10.5.2, JackOSX.0.76, and linuxsampler_20080107

I'm getting the following audio driver error (see below).
Ok up to step 4.2 in http://www.linuxsampler.org/osx.html
It doesn't want to create an audio device.
JackPilot shows that is it still running ("Stop" button is visible)
Any ideas what to do ?

Thanks,
Paul

I suggest that you carefully read JackOSX documentation especially the part concerning "Aggregate devices". You should try to setup jack outside of any use with LS, that is :

- configure audio device for your machine (especially if you are using a Mac Intel machine)

- try to use standard applications like iTunes or Quicktime with jack

- when this is running, try using LS
