We are developing a small audio utility for the music Industry with
simple recording functionality. A great deal of our customers use
firewire audio interfaces.
Expected behaviour : When we select "dflt" as our input then the
documentation states the input chosen in the system preferences will
be used. It is not.
Recording does work in the standard Quicktime player so there are no
obvious technical problems. REV creates a file according to the
settings but no audio is present in that file.
We have read the entries on "enhancement" for recording video and
audio in the bug database but do NOT consider this bug an enhancement
request since "dflt" SHOULD under all circumstances record from the
input set in the system preferences as stated in the documentation.
We have tested this with M-Audio Project Mix , Apogee and ECHO
USB recording from a simple webcam does work so devices other than the
original internal and external inputs are being recognized, just not
the firewire ones.
None of the searches in our forum database has yielded a recent answer.
We can not proceed with the product as is under Revolution.
Hopefully there is a solution or work-around for this or we are
Maybe somebody on the list knows. Any help appreciated.
