M-Audio Delta 66 problem with Rev. E cards.
Update: solved by Delta 1010LT impersonation.
MAudio has been well known for making great sound cards working with Linux for a long time.
Now they silently ships Rev E (which I unfortunately got) of the Delta 66 card and suddenly it just don't work. At least not in Ubuntu 6.06 or Ubuntu 7.10.
You can follow the thread on https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3327 but for now I can sadly only advice you to stay away from M-Audio on Linux. Too bad because I have a long and positive experience professionally of the Delta 44.
In Ubuntu 8.04 the card works if modules.conf is twekaed a little. Read last comment on this page :
I have my sound card working!! I set a diferent model for my Delta66 in /etc/modprobe.d/alsa-base. I put “options snd-ice1712 model=delta1010lt”.
I guess this means the Delta 66 rev E really is a Delta 1010lt with a different breakout box. I'm very happy with the unit and it sounds great now that I got it working. My experience of third party sound cards is that they sound much better than built in cards. A 96khz 24 bit prosumer grade like the MAudio or Audiotrak Maya II (no linux support unfortunately) makes a differnece you can actually hear compared to the builtins.
