I suppose it was in 2009 when I stared using a firewire audio interface for listening to music. At that time, with Ubuntu 9.04 or so, you needed to install some libraries such as Juju, FFADO, and Jack by yourself. (I was not very interested in Ubuntu Studio.)
Now, the year is 2015, and what do I have to do with Ubuntu 14.04 TLS?
I asked Google, and found this article: https://lists.ubuntu.com/archives/ubuntu-studio-devel/2014-May/005797.html.
And in the file, https://github.com/takaswie/snd-firewire-improve/blob/master/sound/firewire/bebob/bebob.c, it says:
/* * bebob.c - a part of driver for BeBoB based devices * * Copyright (c) 2013-2014 Takashi Sakamoto * * Licensed under the terms of the GNU General Public License, version 2. */ #define VEN_PRISMSOUND 0x00001198 static const struct ieee1394_device_id bebob_id_table[] = { /* PrismSound, Orpheus */ SND_BEBOB_DEV_ENTRY(VEN_PRISMSOUND, 0x00010048, &spec_normal),
So there are some developments going on. Let’see what happens in my environment.

Let’s try Audacity with QjackCtl.
Or from CLI using aplay:
% cat .asoundrc pcm.rawjack { type jack playback_ports { 0 system:playback_1 1 system:playback_2 } capture_ports { 0 system:capture_1 1 system:capture_2 } } pcm.jack { type plug slave { pcm "rawjack" } hint { description "JACK Audio Connection Kit" } } pcm.!default { type plug slave { pcm "rawjack" } }
% jackd -R -dfirewire -r44100 -p4096 -n3 % aplay -D pcm.jack Music/01-Taking_Chances.wav
Or using alsaplayer:
% alsaplayer -i text -o jack -d "system:playback_1,system:playback_2" Music/01-Taking_Chances.wav
