This should allow us to automatically probe devices using the recent firewire drivers, as well as some USB devices people have been asking about lately. Sorry that it has taken some time since I said I would work on this patch set, and I've rewritten and rethought it as well a few times. Anyway, here's a proposal. * Exact-channels can be set to false to allow devices to be opened with any channel count instead of just the one specified in the channel map. PA will make a standard ALSA channel map for the additional channels. * Fallback profiles will only be considered if all other profiles fail. * Then we add a "generic" fallback profile without the exact-channel restriction. We don't want this "generic" profile to show up for normal devices, hence the fallback logic. It's the fallback stuff I'm most unsure about, e g if things can be fallback in one direction but not the other, this algorithm is not perfect. This probably needs another patch revision, but I'm sending this out for your additional comments, thoughts and (hopefully) testing. I'm also unsure of what ports (if any) to add for the generic mapping, and if it should be called "multichannel" instead of "generic", or something else.
