:use any jack app (even something as trivial as jack_metro). use qjackctl

Excellent suggestion Paul... will try it.   Have just discovered that selecting 
48000 or 44100 seems to impact the problem (no prob at 44100)

:this has been confirmed. i think the max count so far is 5 delta 1010's.

Terrific!!   The concept works somewhere.

:actually, this is a little unfair as a "stress test". most drivers are

Its hard to be 'unfair' to software.   It just doesn't seem to care
one way or the other.

A very rational suggestion.   However, please be aware than anyone debugging,
developing a driver or otherwise messing with hardware from a company that 
went under over 8 years ago isn't likely to be very rational about why 
they are doing it.   It's similar to a quest to get 192khz out of an Amiga or
install democracy in Iraq.

This is actually a great read.  In particular, it points out some things that you
absolutely have to do in order to be successful commercially (mainly, look the
part, say the right things, and leave a good impression).

My observation:
Music and money are similar to sex and money.
All the elements are there, but all of the fun has been taken out of it.

The harder you try to make money while having fun, the less of both you will get.
