[ecasound] using .ewf input causes copious output

Hi Kai,

There is now copious output from ecasound when using .ewf files. The
follwing lines are repeated continuously with Global position and
child-pos updated with each iteration:
Global position (in samples): 147456
child-pos: 147456
child-offset: 0
child-startpos: 0
child-length: 1132297
child-active: 1

This output causes a problem for my pyeca eci scripts. The eci parser
buffer overflows. I've put a simple test case, .ewf and .wav file here:
running debug2.py causes the following error messages:

(ecasoundc_sa) Error='read() error', cmd='engine-status' last_error=''
cmd_cnt=8 last_cnt=7.

* Message from libecasoundc:
* Connection to the processing engine was lost. Check that ecasound
* is correctly installed. Also make sure that ecasound is either
* in some directory listed in PATH, or the environment variable
* 'ECASOUND' contains the path to a working ecasound executable.

(ecasoundc_sa) Error='sync error', cmd='stop' last_error='' cmd_cnt=9

This does not happen if I use the .wav file dirrectly.

Let me know if there is anything further I can do to help debug this, or
if I'm just doing (or not doing) something stupid.

Eric Rz.
