OK I've reemerged python and ran python-updater.
Problems remain the same although the script works until it stops and gives
the error messages from above.
The script is a slighty modified (In/Outputs) version of the one that comes
with ecasound documentation:
#!/usr/bin/env python
1 Setup ECI to read audio from file, apply a 100Hz lowpass filter, and send it
to the soundcard (/dev/dsp).
2 Every second, check the current position. If the stream has been running for
over 15 seconds, exit immediately. Also, every second, increase the lowpass
filter's cutoff frequency by 500Hz.
3 Stop the stream (if not already finished) and disconnect the chainsetup.
Print chain operator status info.
import time
from pyeca import *
cutoff_inc = 500.0
e = ECA_CONTROL_INTERFACE()
e.command(cs-add pass_jack)
e.command(c-add chain01)
e.command(ai-add jack_auto,xine)
e.command(ao-add jack_auto,MONITOR)
e.command(cop-add -efl:100)
e.command(cop-select 1)
e.command(copp-select 1)
e.command(cs-connect)
e.command(start)
while True:
time.sleep(True)
e.command(engine-status)
if e.last_string() != running: break
e.command(get-position)
curpos = e.last_float()
if curpos 15: break
e.command(copp-get)
next_cutoff = cutoff_inc + e.last_float()
e.command_float_arg(copp-set, next_cutoff)
e.command(stop)
e.command(cs-disconnect)
e.command(cop-status)
print Chain operator status: , e.last_string()

Hello list,
a few days ago my creative urge forced me to learn python. As a first
step I wanted to control ecasound by script.
What a pity that it doesn't work.

I did revdev-rebuild. In that sense my system seems to be consistence.
Should glibc be downgraded? Wrong USE variables?
you can't downgrade glibc.
re-emerge python and use python-updater.
And since you are using sabayon, file a bug in their bugzilla.
Neither python or glibc nor ecasound are in the sabayon overlay.
