I still have a devil of a lot of problems plaing ALAC files that are not 16/44.1. Indeed, they don't play, or play with the most horrible noise you can imagine.
Is there a pointer to a post on how you would prefer to have bug reports uplinked? I dind't mind spending the $50 for a license, because it has s much potention. But ...
In Options > File Types, make sure AAC (m4a, etc.) is set to 'Automatic'.
A coming build will do this automatically.
If you still have problems, please start a new thread and we'll get to the bottom of it.
Thanks.
