David, >> Firewire speakers are just three models. >> (Vendor ID/Model ID) >> iSight: 0x000a27:0x000010 >> Griffin: 0x001292:0x00f970 >> Lacie: 0x00d04b:0x00f970 I wrote a test for udev rules. Please see attached files in order of: -> lsfirewire.log -> cards.log -> 0001-udev-add-entries-for-firewire-sound-devices-sample.patch -> udevadm.log -> pulse.log I don't have devices of the first three entries. But an entry for 'Behringer F-Control Audio 202' has the same condition and actually 'analog-stereo' profile is applied. So these three devices may also have profiles except for 'multichannel.conf'.
