[LAU] OT: hdsp not happy with recent kernels

[peter at peterlutek.com]

ok.... so after all this:

1. there ARE folks successfully using a Mutiface on an ExpressCard adapter
with kernels more recent than 3.1.

2. there is a lot of discussion about pulseaudio -- i don't have
pulseaudio on this machine.

3. there is some discussion about dbus -- not sure if that applies or not,
but the jack failure happens the same way in qjackctl with "Enable D-Bus
interface" box UNchecked, so i think not.

to review, here's what happens when jack falls over for me with kernels
beyond 3.1-6 (note that this is in a boot in which i have not touched
hdspmixer, so let's forget about *that* issue for now!):

should i try jack1, instead of jack2?
any other ideas, or troubleshooting bits i should post?

note also that, once jack has failed, hdspmixer won't start, AND vice
versa, so i think there may be some aspect of this that is "behind the
scenes" and common to both. when started on a clean boot, hdspmixer fails
thusly:
