alsa_out no longer loading second interface

As detailed in this thread,a few days ago I had managed to setup an old M-Audio FastTrack Pro card to work with jack and use all the inputs/outputs it offers.
The FastTrack is actually a 2 cards/interface and jack only sees one of them at the time, with a maximum of 2in/2out instead of the max 4/in/4out. The key to unlocking the additional 2 ports was to use alsa_in or alsa_out (depending on configuration). This system worked perfectly until yesterday. Now I can no longer load additional output ports in jack with alsa_out. I get the error:

$ alsa_out  -d hw:5,0
Sample format not available for playback: Invalid argument
Setting of hwparams failed: Invalid argument

I do not understand this error, I'm afraid. Here is the output of aplay/arecord  -l detailing my configuration, plus the content of /proc/asound/cards:

My audio interface is on slot 5, with devices 0 and 1. Jack is configured to have its output on hw:Pro,1 [USB Audio], which is card number 5, so "alsa_out -d hw:5:0" should give access to the other two (analog) output ports. Not so, or rather not any longer:

stefano@gorgias ~ $ alsa_out -j "Fast Track Analog out" -d hw:5,0
Sample format not available for playback: Invalid argument
Setting of hwparams failed: Invalid argument

The only problem I can see---and I may be totally wrong---is that aplay -l reports both the internal audio and the Fast Track interface as being on device 0, even though they are on different cards. May that be the issue?
Here is my alsa_base.conf file:
