Changing the sample rate for the "Digidesign CoreAudio Manager"
Hi all,
I'm having trouble with the sample rate with ProTools. I have the a ProTools 9 HD2 on a Mac OSX 10.6. What I want to do is to use WaveBurner from Logic Studio 8. This needs the CoreAudio Manager to be set at 44.1 kHz to work. For a while I could live with the workaround, see thread: http://duc.digidesign.com/showthread.php?t=284363 . I used a PT9 44.1 kHz project to change the clock speed, and it switched to the proper speed and stuck there as it should. But since this week, when I start the CoreAudio Manager it switches to 48 kHz, even though I changed the preference in Audio-Midi-Setup to 44.1. The only change was a OSX update, no software update or any intentional change was made in the meantime. - So what is the proper way to switch the clock setting? - I can't select any other sample rate in the CoreAudio Managers HW Setup, they are all greyed out. Is this intentional? - When I change the speed in the AudioMidiSetup, nothing happens. How can I apply my new settings? - Is there a file which has the 48kHz setting for the CoreAudioManager and does it help to dump that one and have it recreated? Thanks for any hint leading towards a solution... Best regards, mcJack The complete Setup: ProTools HD2 9.0, 2x192 I/O, MacPro 2x2,26 QuadCore, OSX 10.6.5, 12GB RAM, Command8, WaveBurner 1.5.2 (from Logic Studio Pro 8) |

Typically the best way to change the sample rate or buffer size is to launch CAM, then launch the app you want to use - typically you would change the buffer or SR in it's hardware setup. In Waveburner, go to Preferences>Audio and make sure the Digi Core Audio is selected. You should then be able to change the SR or buffer size in CAM. |

What can make the CAM think that waveburner needs 48 kHz? I don't see any switch in the WB preferences... |

Can you try trashing preferences, including the specific Core Audio preferences, per the info in the General Troubleshooting thread?

Seems like only when this file is recreated the setting is read from the Audio-Midi-Setup (AMS). How can I change this setting without trashing the whole file? I won't use a Hex-Editor as this file is binary coded. Is it a bug or a missing feature in the CAM? Or is there simply a deadlock between AMS writing the setting and the CAM reading an not being allowed to change it afterwards? But thanks for your help so far, at least I am now able to achieve another clock speed |

Ok, thank you.
Maybe in 9.1 the CAM synchronizes this with the AMS selected value ;-) |
