Is anyone using MIDI on a M-Audio 24/96 (ICE1712) card? I've had one for
several years and keep using my little USB adapter because the card just
doesn't work.
Well, it works fine for audio. And it pretends to work for MIDI as well.
But, after playing a few songs it has a tendency to hang my system.
Completely. When it hangs the keyboard is frozen; not even the power
button the computer responds. I have hit <RESET> and then deal with the
"not cleanly shutdown" stuff later.
When I first got the card I had some discussions on the alsa lists.
Nothing really happened with that so I assumed that a new version of
alsa and/or linux would solve things. Well, I've gone though more than a
few updates and I think this is the 3rd motherboard ... and still the
same problem.
So, anyone with success? Otherwise I'm going to assume that there is a
problem with the hardware on the card. But, really it does seem to me to
be a driver problem. I'd like to dump the USB interface to free up a port.

I've been running one of these without the slightest problem for some
time. Originally on Mandrake 9.1 (yeah, that long ago) but now on
64studio. It's been on two different mobos.

I've used that card about two years ago, without having such problems.
I assume, you have some conflict with interrupts or so.
What does
$ cat /proc/interrupts
say, with the card plugged in?
I've had the same annoying problem (system freeze) on some computers, when
pressing keys on the keyboard, while it was accessing the harddrive.
Though I never found a sollution for this.
Maybe, changing the interrupts on the card or in the bios would help,
I'm not shure..

Thanks, all, for the responses. Yes, this card works fine for me EXCEPT
for MIDI.

Nothing leaps out at me.
When the freeze happens I'm not doing other things. Just listening.
I don't believe the the interrupts on the card can be changed??? Are
they not handed out by the PCI stuff when the computer boots?

I have used the card with two mobos, currently with smp machine. No
problems.
I think this is the bug you are referring to:

I can't access the bugtrack page ... first off I get a certificate
problem (which I skipped over), then it needs me to log in :) Can you
post the bug, or if it's too long send it to me.
Thanks.

Yes, that certainly seems to be the same bug as the one I'm having.
I reported this to the alsa bunch several years ago and the diagnosis at
the time was a spin-lock problem. That was problably 3 or 4 alsa
versions ago, but it still seems to be present. For what it's worth, I'm
running Ubuntu with a stock 2.6.22-14-generic kernel and alsa 1.0.14.
Could be that the bug reporter and I have the a card from the same
batch, but I really do suspect that there is a bug in alsa.

How odd, that it works for everyone but me :)
I'm wondering ... would my cable length have any effect on this? I'm
using about 8ft between the computer and synth (A casio WK3000). I'm
sure that MIDI is designed for much longer runs, but it's a thought.
Also, could this be a problem with aplaymidi? That's about the only
program I use consistently to play MIDIs. But, it works flawlessly with
the USB interface.

Same here. Both ootb and JAD.
