I dunno, I think Paul's thoughts sound sensible. Its not solved in a simple
manner, but it was obviously solved somehow with other driver
architectures.
With very little success when a complicated hardware is in the machine.
I can't remember having any real problems with this on Windows, or hearing about any such problems from others? There was the problem with Logic Audio not coping with Hammerfall's variable numberof channels, but I think other applications worked fine.
Will this database cope with runtime variables, such as the number of channels with RME Hammerfall though (dependent on samplerate)?
It depends on our goals and what we expect from this information. Can you describe your requirement (for what reason, you need this information?).
I'm one of the developers responsible for the ALSA implementation of a cross
platform audio wrapper called PortAudio (www.portaudio.com), which gathers
info about available devices during startup. Also, when using this library
myself, I would like to be able to display a list of devices/channels to
choose from (I normally use channels 17/18). Anyway, such information is
seemingly easily obtained with other driver architectures, any reason why
this shouldnt be available to Linux users (disregarding the implementation
issue)? Personally I see no reason to inhibit flexibility beyond what we
see as immediately useful.
