Hi Adam,
I have the same problem.
Are you sure is an echo canceller problem?
Following advices from this list I discovered that I had an IRQ shared.
Untill now I didn't try the new setup but I really hope that this was the
problem.
If you manage to solve the problem in any way please give me advise.
Ciao
You can make sure the card is sitting on it's own IRQ - use the command
cat /proc/interrupts
You can also check that the card isn't losing interrupts by running the
zttest proram:
/sbin/zttest
There's more on interrupts here:

It's aimes at the TDM400P card, but I'd be surprised if the 2400P is that
much different (but someone please correct me if it is!)
