This sounds very much like what happened on my machine, for no known 
reason (except for maybe changing the USB port)

Hmm, how many ports should you have on a Fast Track Ultra (w/o 8R)?

No, I don't have *any* knowledge about asoundrc configuration. I've not 
been using one for many, many years.

And, since you asked, here's my stream0 (could you please post yours if 
it is different):

  ~$ cat /proc/asound/F8R/stream0
M-Audio Fast Track Ultra 8R at usb-0000:00:1a.7-4, high speed : USB Audio

Playback:

And here's the stream0 while playing a Hydrogen song:
