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.

Neither python or glibc nor ecasound are in the sabayon overlay. -- mailto: [EMAIL PROTECTED] gnupg fingerprint: 56DA 4E32 3A4A 52AC B769 DFC2 BF3E 9805 09BB 4259 -- gentoo-user@lists.gentoo.org mailing list
