This does not appear to be a USB sharing problem.

OK. Next step is to dig in to what these mean:
[ 46.508331] ALSA urb.c:480: frame 0 active: -75
[ 46.560332] ALSA urb.c:480: frame 0 active: -75
[ 98.971734] ALSA urb.c:146: timeout: still 7 active urbs..
[ 104.970917] ALSA urb.c:146: timeout: still 2 active urbs..
[ 121.260876] ALSA pcm.c:223: 4:2:1: usb_set_interface failed
Others might know what these mean.
Me? I don't. I'd have to inspect the kernel source code. urb.c and
pcm.c are file names in the kernel sources (possibly in the sound/
folder). The number after the colon (:) is a line number. So, if you
go to urb.c line 480, you see something like printk(KERN_ERR "frame:
%d active: %d", frame, active); The code around might give a clue to
what actually failed.
