Definitely.

Let me now reset my PC so that it will boot from its Windows7 partion.

With Audacity and a vendor supplied control software, my Orpheus
plays 44.1kHz 2-ch sound perfectly.

Also,

for more than five years, not with the same PC but with the same cable,
during which time I have never experienced a trouble.

And before doing clean install of Ubuntu 15.04 (kernel 3.16) a few days ago,
I confirmed that:

% jackd -R -dfirewire -r44100 -p4096 -n3 &
% aplay -D pcm.jack test.wav
or
% alsaplayer -i text -o jack -d "system:playback_1,system:playback_2"
test.wav

works all right on Ubuntu 14.04 with kernel 3.13.

So I have an impression that this is not a hardware but a software problem,
perhaps specific to snd-bebob..

Any suggestions will be appreciated. Thank you again for taking your time.
