Ecasound a bit shy on information

Hello all!
   Ecasound is a bit shy, when it comes to warning me. I just had a big
chansetup, one file had the wrong samplerate (not the standard). Ecasound went
ahead quietly ignoring it, not playing it, which was a pity, because it took
me a long time finding it.
   Usually, I think it does notify the user of such mishabs. any idea what
might have happened?
   Friendly regards
           Julien

Hi,

...this is an old problem. E.g. already in 2002 we had items like:

"Better checks for parsing operator arguments."
http://sourceforge.net/tracker/?func=detail&aid=2134179&group_id=4605&atid=104605

... and it's still not closed. Quite a bit work has been done, but
definitely a lot more could be done.

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
welcome!

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)...?

Hello Kai!
   Ecasound didn't get me any error message. Not that I could find it. It just
started working and all else was as it should have been. Only the input with
the incorrect samplerate was missing.
   I'll rerun the chainsetups though with all errors in place and see what I
can get.
   Warm regards
          Julien
