[LAU] JACK not working with Audiophile 2496 anymore

[david]

I get these messages from JACK when I start it using QJackCtl, trying to 
use my AudioPhile 2496. This is running on Debian Sid, uname -a reports 
"3.14-2-amd64 #1 SMP Debian 3.14.15-2 (2014-08-09) x86_64 GNU/Linux" 
(but I was getting the same error on kernel 3.02.4 before that.) I am a 
member of the audio group.

JACK starts and runs fine if I pick the "default" interface, but that 
doesn't play any audio through the Audiophile. (I have no idea what it's 
playing through.)

While parts of Pulse are installed, according to "killall pulse" Pulse 
audio is not running. Trying to remove the installed Pulse packages 
wanted to also remove a bunch of other apps, such as csound, GIMP, some 
KDE4 apps, etc.

I found an old thread on a forum where the poster said installing 
"dbus-python" fixed it, but the closest package I could find similar to 
that name is "python-dbus" and it's installed.

This is a fresh Debian Sid install and my first experience with Debian's 
move to systemd instead of good old reliable init, so could that be 
messing things up? Or that it's using PAM (my prior Debian experience 
didn't include PAM) and htop shows a number of (sd-pam) processes running)?

These problems originally began when I had to reset the BIOS, which 
re-enabled the motherboard audio. I tried disabling the motherboard 
audio, but then ALSA wouldn't load at all.

My replacement desktop system is too modern to support such old 
equipment as the Audiophile, it would be nice to have it working in the 
old desktop system where it worked fine for many years, but now no 
longer works.
