Sure thing...I am editing a project on my laptop..Premiere has been running great on my iMac...however, it will not play anything on my MacBook Pro...it will play about a second and then stop...then return to the playheads original position...it does this on every type of media. I have searched and searched and tried everything suggestion I have come across..which involves in deleting the com.apple.audio preference, and logging in as the root user...however, nothing is working. I have created a new project and still get the same outcome...I have a new MacBook Pro so it should not have a problem playing the media...especially a simple aif file.
Just as an example, can you layout a typical Project/Sequence with the full data, and then an example Asset, again with full details?
Not knowing Mac's, I would be helped with info such as processor/CPU speed and core-count, and also the I/O sub-system, i.e. number, size, speed, controller type and how allocated for your HDD's.
Thanks for letting us know the steps that you have tried, as those can now be ruled out as possibilities.
