In general, I recommend raising specific problems on the list, perhaps
explaining what kind of error message or warning, would you have expected.
With this info, adding stricter checks and proper error messages is fairly
straighforward. Patches to the error messages themselves are also warmly

Esperically for me personally, noticing these, sometimes very stupid
omissions, can be difficult. I've used ecasound for +10 years and I'm too
accustomed to the interface at this point. Plus I tend to still follow the
same usage patterns as before, so in my own non-testing use of Ecasound I
only use limited part of the interface (and most probably unknowingly
avoid existing pitfalls).

Hmm, this sounds more like a bug. Ecasound should raise an error if a
chainsetup has two or more objects with locked sampling rates (= rate
cannot be set to an arbitrary value), and not all rates match. The check
is done when you issue "cs-connect". What did "cs-connect" output in your
case... (if anything)...?
