[Jack-Devel] Is a M audio 1010lt too old to use with jack?

[Tim]

My Delta 1010L works fine.
It looks like Jack is running, below.

Maybe you're not getting any sound from the card?
For this card, try a good mixer, to adjust the hardware volumes.
There is envy24, and mudita24, both tailored for this card.
You can also try a general-purpose mixer like QasMixer.

Beyond that have a look at the documentation at the jack website.
It will tell you how to optimize the system by setting various
  limits and maybe get rid of the "ERROR: Cannot lock down" message.

One tip I can offer: Extensive tests on different modern multi-core
  PCs running either Linux or Windows showed that this card does not
  like all CPU cores enabled. Yours might have the same problem.
Symptoms are popping, crackling, and noise in the sound.
Unless someone has found a better fix, you'd likely want to turn
  off all but one core with commands like this, for a quad core CPU:

echo 0 | sudo tee /sys/devices/system/cpu/cpu1/online
echo 0 | sudo tee /sys/devices/system/cpu/cpu2/online
echo 0 | sudo tee /sys/devices/system/cpu/cpu3/online

Where cpu0 is left running.

(You can also do the same thing with most motherboard BIOS
  setup features.)
