I am going to test this driver with LaCie FireWire Speakers and Griffin FireWave RSN. BTW, FireWave is a 6-channel-out device which is targeted to be used on OS X as either a stereo or a 5.1-Dolby-surround output. I heard that the 5.1 mode is configured by a vendor-specific AV/C command. (The FireWave was sold with an OS X driver; without this vendor driver it just works as a stereo-out soundcard with OS X' stock driver.)
Jay has already tested the FireWave in 6-channel mode; in fact, this was the only format that the previous patch supported for the FireWave.
If OS X works with two channels without knowing that the device expects six, this implies that the device automatically detects the format of the incoming stream, and that sending Dolby data (which would just be two-channel data labeled as "SPDIF") should work too.
